ВОЗМОЖНОСТИ ПРИМЕНЕНИЯ НЕИНВАЗИВНЫХ ОФТАЛЬМОЛОГИЧЕСКИХ МЕТОДОВ ДИАГНОСТИКИ ПАТОЛОГИЧЕСКИХ СОСТОЯНИЙ ПРОЦЕССА РАННЕГО СТАРЕНИЯ НА МОДЕЛИ ПРИМАТОВ

Currently, there is an urgent need for early diagnostics, searching for means of predicting the development of cognitive deficit, and assessing the dynamics of changes during treatment. Given the common origin of the brain and eye, which undergo the same onto- and phylogenetic development, some researchers have suggested that the eye can act as a “window” for easily accessible and non-invasive methods for studying brain pathology [3]. The popularity of fundamental research is growing, and interest in creating disease models in primates is becoming more relevant. The creation of such models will significantly expand the possibilities of obtaining the most reliable information, especially in the field of gerontology and brain pathology (cataract, senile ring, age-related changes in the fundus and other signs of early aging). In this part of the work, approaches to studying the fundus, physiological parameters of the structures and functions of the visual organ in rhesus macaques and hamadryas baboons of different ages are developed; potential ophthalmological biomarkers for diagnosing early aging processes are considered. A combined approach using ophthalmological markers, including non-invasive visualization of the retina and detection of pathological proteins in the intraocular fluid, lens or retina, in combination with biomarkers of oxidative stress (malondialdehyde, lipofuscin, protein carbonyls, 8-OH-deoxyguanosine) will allow us to develop a methodology for diagnosing the development and correction of early aging in humans on a primate model.

Leaf Functional Traits and Their Influencing Factors in Six Typical Vegetation Communities.

Leaf functional traits (LFTs) have become a popular topic in ecological research in recent years. Here, we measured eight LFTs, namely leaf area (LA), specific leaf area (SLA), leaf thickness (LT), leaf dry matter content (LDMC), leaf carbon content (LCC), leaf nitrogen content (LNC), leaf phosphorus content (LPC), and leaf potassium content (LKC), in six typical vegetation communities (sclerophyllous evergreen broad-leaved forests, temperate evergreen coniferous forests, cold-temperate evergreen coniferous forests, alpine deciduous broad-leaved shrubs, alpine meadows, and alpine scree sparse vegetation) in the Chayu River Basin, southeastern Qinghai-Tibet Plateau. Our aim was to explore their relationships with evolutionary history and environmental factors by combining the RLQ and the fourth-corner method, and the method of testing phylogenetic signal. The results showed that (i) there were significant differences in the eight LFTs among the six vegetation communities; (ii) the K values of the eight LFTs were less than 1; and (iii) except for LCC, all other LFTs were more sensitive to environmental changes. Among these traits, LA was the most affected by the environmental factors, followed by LNC. It showed that the LFTs in the study were minimally influenced by phylogenetic development but significantly by environmental changes. This study further verified the ecological adaptability of plants to changes in environmental factors and provides a scientific basis for predicting the distribution and diffusion direction of plants under global change conditions.

Neurovisceral interactions in individual and phylogenetic development

The article provides a review of experimental studies exploring the nature of neurovisceral interactions through the analysis of heart rate variability at different stages of individual development and within different species. Analysis of heart rate variability is one of the most common and accessible experimental methods to observe aspects of neurovisceral (for example, neurocardiac) interactions. Nonstationary, nonlinear components in the dynamics of inter-beat intervals (periods between adjacent heart beats) reflect the processes of coordination of heart activity with changes in the organization of neural activity, ensuring the current relationship of the individual with the environment. Mathematically, these aspects of heart rate dynamics are expressed in estimates of the complexity, irregularity, entropy, and unpredictability of the time sequence of inter-beat intervals. The dynamics of neurocardiac interactions described in this way are not the same in different species and become more complex in phylogeny. Similarly, in individual development, the dynamics of the heart rate becomes more complex and reflects, among other things, the degree of maturation of certain nervous structures at different stages of ontogenesis. We examined the features of the dynamics of neurovisceral interactions in individual and phylogenetic development within the framework of the system-evolution theory and interpreted them in connection with changes in the structure of individual experience – the characteristics of a set of functional systems actualized in behavior (increasing differentiation of the relationship between the individual and the environment).

Phylogenetic relationships, selective pressure and molecular markers development of six species in subfamily Polygonoideae based on complete chloroplast genomes

The subfamily Polygonoideae encompasses a diverse array of medicinal and horticultural plants that hold significant economic value. However, due to the lack of a robust taxonomy based on phylogenetic relationships, the classification within this family is perplexing, and there is also a scarcity of reports on the chloroplast genomes of many plants falling under this classification. In this study, we conducted a comprehensive analysis by sequencing and characterizing the complete chloroplast genomes of six Polygonoideae plants, namely Pteroxygonum denticulatum, Pleuropterus multiflorus, Pleuropterus ciliinervis, Fallopia aubertii, Fallopia dentatoalata, and Fallopia convolvulus. Our findings revealed that these six plants possess chloroplast genomes with a typical quadripartite structure, averaging 162,931 bp in length. Comparative chloroplast analysis, codon usage analysis, and repetitive sequence analysis demonstrated a high level of conservation within the chloroplast genomes of these plants. Furthermore, phylogenetic analysis unveiled a distinct clade occupied by P. denticulatum, while P. ciliinrvis displayed a closer relationship to the three plants belonging to the Fallopia genus. Selective pressure analysis based on maximum likelihood trees showed that a total of 14 protein-coding genes exhibited positive selection, with psbB and ycf1 having the highest number of positive amino acid sites. Additionally, we identified four molecular markers, namely petN-psbM, psal-ycf4, ycf3-trnS-GGA, and trnL-UAG-ccsA, which exhibit high variability and can be utilized for the identification of these six plants.

Morphological heterogeneity of neurons in the human central amygdaloid nucleus.

The central amygdaloid nucleus (CeA) has an ancient phylogenetic development and functions relevant for animal survival. Local cells receive intrinsic amygdaloidal information that codes emotional stimuli of fear, integrate them, and send cortical and subcortical output projections that prompt rapid visceral and social behavior responses. We aimed to describe the morphology of the neurons that compose the human CeA (N = 8 adult men). Cells within CeA coronal borders were identified using the thionine staining and were further analyzed using the "single-section" Golgi method followed by open-source software procedures for two-dimensional and three-dimensional image reconstructions. Our results evidenced varied neuronal cell body features, number and thickness of primary shafts, dendritic branching patterns, and density and shape of dendritic spines. Based on these criteria, we propose the existence of 12 morphologically different spiny neurons in the human CeA and discuss the variability in the dendritic architecture within cellular types, including likely interneurons. Some dendritic shafts were long and straight, displayed few collaterals, and had planar radiation within the coronal neuropil volume. Most of the sampled neurons showed a few to moderate density of small stubby/wide spines. Long spines(thin and mushroom) were observed occasionally. These novel data address the synaptic processing and plasticity in the human CeA. Our morphological description can be combined with further transcriptomic, immunohistochemical, and electrophysiological/connectional approaches.It serves also to investigate how neurons are altered in neurological and psychiatric disorders with hindered emotional perception, in anxiety, following atrophy in schizophrenia, and along different stages of Alzheimer's disease.

Chloroplast genome analyses of Caragana arborescens and Caragana opulens

BackgroundNumerous species within the genus Caragana have high ecological and medicinal value. However, species identification based on morphological characteristics is quite complicated in the genus. To address this issue, we analyzed complete plastid genome data for the genus.ResultsWe obtained chloroplast genomes of two species, Caragana arborescens and Caragana opulens, using Illumina sequencing technology, with lengths of 129,473 bp and 132,815 bp, respectively. The absence of inverted repeat sequences in the two species indicated that they could be assigned to the inverted repeat-lacking clade (IRLC). The genomes included 111 distinct genes (4 rRNA genes, 31 tRNA genes, and 76 protein-coding genes). In addition, 16 genes containing introns were identified in the two genomes, the majority of which contained a single intron. Repeat analyses revealed 129 and 229 repeats in C. arborescens and C. opulens, respectively. C. arborescens and C. opulens genomes contained 277 and 265 simple sequence repeats, respectively. The two Caragana species exhibited similar codon usage patterns. rpl20-clpP, rps19-rpl2, and rpl23-ycf2 showed the highest nucleotide diversity (pi). In an analysis of sequence divergence, certain intergenic regions (matK-rbcL, psbM-petN, atpA-psbI, petA-psbL, psbE-petL, and rps7-rps12) were highly variable. A phylogenetic analysis showed that C. arborescens and C. opulens were related and clustered together with four other Caragana species. The genera Astragalus and Caragana were relatively closely related.ConclusionsThe present study provides valuable information about the chloroplast genomes of C. arborescens and C. opulens and lays a foundation for future phylogenetic research and molecular marker development.

Endo-Adaptive Component Taraxacum Officinale L. as a Determinant of the Adaptation Syndrome of Plant Organisms in the Background of Ecosystem Stability

The research aim is to find out the specificity of the endo-adaptive component (Taraxacum Officinale L.) as a determinant of the adaptation syndrome of plant organisms against the background of ecosystem stability. The theoretical-methodological basis of the work was the synergistic use of scientific principles and a systematic approach, which determined a transparent approach to the choice of research methods: general scientific, general biological, mathematical statistics. It has been proven that in modern conditions, plants adapt to changes in the environment due to various adaptation mechanisms (xeromorphic features, etc.) which were formed in the process of phylogenetic development and which determine the existence of drought-resistant plants. It is shown that the reactions-responses of plants help to identify the main components of xeromorphism, to investigate the corresponding changes in the formation of the general adaptation syndrome of the plant organism.

Assembly and analysis of the complete mitochondrial genome of Forsythia suspensa (Thunb.) Vahl

BackgroundForsythia suspensa (Thunb.) Vahl is a valuable ornamental and medicinal plant. Although the nuclear and chloroplast genomes of F. suspensa have been published, its complete mitochondrial genome sequence has yet to be reported. In this study, the genomic DNA of F. suspensa yellowish leaf material was extracted, sequenced by using a mixture of Illumina Novaseq6000 short reads and Oxford Nanopore PromethION long reads, and the sequencing data were assembled and annotated.ResultThe F. suspensa mitochondrial genome was obtained in the length of 535,692 bp with a circular structure, and the GC content was 44.90%. The genome contains 60 genes, including 36 protein-coding genes, 21 tRNA genes, and three rRNA genes. We further analyzed RNA editing of the protein-coding genes, relative synonymous codon usage, and sequence repeats based on the genomic data. There were 25 homologous sequences between F. suspensa mitochondria and chloroplast genome, which involved the transfer of 8 mitochondrial genes, and 9473 homologous sequences between mitochondrial and nuclear genomes. Analysis of the nucleic acid substitution rate, nucleic acid diversity, and collinearity of protein-coding genes of the F. suspensa mitochondrial genome revealed that the majority of genes may have undergone purifying selection, exhibiting a slower rate of evolution and a relatively conserved structure. Analysis of the phylogenetic relationships among different species revealed that F. suspensa was most closely related to Olea europaea subsp. Europaea.ConclusionIn this study, we sequenced, assembled, and annotated a high-quality F. suspensa mitochondrial genome. The results of this study will enrich the mitochondrial genome data of Forsythia, lay a foundation for the phylogenetic development of Forsythia, and promote the evolutionary analysis of Oleaceae species.

Evolution of a Model System: New Insights from the Study of Anolis Lizards

Following decades of intensive study, Anolis lizards have emerged as a biological model system. We review how new research on anoles has advanced our understanding of ecology and evolution, challenging long-standing paradigms and opening new areas of inquiry. Recent anole research reveals how changes in behavior can restructure ecological communities and can both stimulate and stymie evolution, sometimes simultaneously. Likewise, investigation of anoles as spatial or phylogenetic evolutionary experiments has documented evolutionary repeatability across spatiotemporal scales, while also illuminating its limits. Current research places anoles as a promising model for Anthropocene biology, with recent work illustrating how species respond as humans reconfigure natural habitats, alter the climate, and create novel environments and communities through urbanization and species introduction. Combined with ongoing methodological developments in genomics, phylogenetics, and ecology, the growing foundational knowledge of Anolis positions them as a powerful model system in ecology and evolution for years to come.

The PhyloCode: The logical outcome of millennia of evolution of biological nomenclature?

AbstractBiological nomenclature harks back to a remote prehistoric past, as shown by the universality of fairly sophisticated folk taxonomies and nomenclatures found on all inhabited continents. Ethnobiologists have suggested that these nomenclatures include cryptic ‘ethnotaxonomic ranks’, although the existence of these ranks has been increasingly questioned recently. The fact that no trace of such ranks has been evoked in Aristotle's classification of animals but that they have been described in antique Roman ethnotaxonomies casts further doubts about these cryptic ranks. The advent of rank‐based nomenclature (RN) in the mid‐18th century has had a pervasive, but not only positive, influence on biological nomenclature. The use of a single type and of a subjective, artificial nomenclatural rank does not delimit taxa under RN. This is even a goal of RN, according to Principle 2 of the Zoological Code. This contrasts with the nomenclatures of other fields, some of which are designed to delimit entities fairly precisely (e.g. geopolitics, stratigraphy, chemistry), and in which ranks are either defined more objectively (e.g. geopolitics, chemistry), or used informally and relegated to a secondary role (e.g. biogeography, paleobiogeography), or vary in time (e.g., paleobiogeography) or space (e.g., stratigraphy). A trend towards more explicit and precise delimitation of entities over time is also discernible in some fields, especially geopolitics and stratigraphy. In this context, the development of phylogenetic nomenclature (PN) and the recent advent of the PhyloCode appear as the logical outcome of the development of evolutionary biology and phylogenetics.

Assembling animals: trees, genomes, cells, and contrast to plants

The Animal Kingdom is an astonishingly diverse group. Together with plants and fungi is one of the three major lineages of multicellular eukaryotes. Due to anthropocentrism and/or genuine scientific interest, their origin and diversification are pivotal to modern evolutionary biology. In the last few decades, dramatic technological advances in molecular biology and computational power have generated new phylogenetic proposals, as well as new tools to compare genomes or study cell type evolution. These new approaches complement the insights from fields such as comparative morphology, evodevo, or palaeontology, which all together provide an integrative view of animal evolution, including major evolutionary transitions such as the origin of animals or the emergence of animals with bilateral symmetry. In this paper, we review recent developments in animal phylogenetics, comparative genomics, and cell type evolution related to these two transitions, and we compare animals to another major lineage of multicellular eukaryotes, plants.

Morphogenetic peculiarities of reproductive biology in sugar beet (Beta vulgaris L.) breeding.

This review considers the processes of morphogenesis used in the development of propagation methods and the creation of a new starting material for sugar beet. It has been demonstrated that methods of particulation, in vitro microcloning and cell breeding that reflect non-sexual forms of plant reproduction increase the effectiveness of breeding experiments. The review describes the in vitro culture methods maintaing a tendency in plants for vegetative propagation and stimulating increase in genetic variability of properties when mutagens such as ethyl methanesulfonate, alien genetic structures with mf2 and mf3 bacterial genes in Agrobacterium tumefaciens strains, and selective agents (Сd++ ions and abscisic acid) are incorporated into plant cells. It presents the results of using fluorescent microscopy, cytophotometry, biochemical analysis and determining the level of phytohormones and content of nucleic acids in nuclei for forecasting the seed setting ability. It has demonstrated that long self-pollination of plants causes decrease in fertility of pollen grains, resulting in the sterilization of male gametes and the appearance of pistillody flowers. Self-fertile plants isolated from these lines serve as sterility fixers, while the apomixis elements increased the ovule number, additional embryo sacs and embryos. A role of apomixis in contributing to variability in the onto- and phylogenetic development of plants have been substantiated. The review reflects the morphological features of the in vitro development of sexual and somatic cells in embryos during the formation of seedlings based on floral and vegetative embryoidogeny. Use of the SNP and SSR (Unigenes) molecular-genetic markers having a high polymorphism level has appeared effective to characterize the developed breeding material and hybrid components when carrying out crossings. The study of sugar beet starting materials for the presence of TRs mini-satellite loci making it possible to reveal O-type plants-pollinators (sterility fixing agent) and MS-form plants are of interest for breeding as well. The selected material can be widely used in breeding to produce hybrids, allowing for a 2-3- fold reduction of the development period. The review also discusses the prospects for the development and implementation of new methods and original schemes in sugar beet genetics, biotechnology and breeding.

Developmental Aspects of Cardiac Adaptation to Increased Workload

The heart is capable of extensive adaptive growth in response to the demands of the body. When the heart is confronted with an increased workload over a prolonged period, it tends to cope with the situation by increasing its muscle mass. The adaptive growth response of the cardiac muscle changes significantly during phylogenetic and ontogenetic development. Cold-blooded animals maintain the ability for cardiomyocyte proliferation even in adults. On the other hand, the extent of proliferation during ontogenetic development in warm-blooded species shows significant temporal limitations: whereas fetal and neonatal cardiac myocytes express proliferative potential (hyperplasia), after birth proliferation declines and the heart grows almost exclusively by hypertrophy. It is, therefore, understandable that the regulation of the cardiac growth response to the increased workload also differs significantly during development. The pressure overload (aortic constriction) induced in animals before the switch from hyperplastic to hypertrophic growth leads to a specific type of left ventricular hypertrophy which, in contrast with the same stimulus applied in adulthood, is characterized by hyperplasia of cardiomyocytes, capillary angiogenesis and biogenesis of collagenous structures, proportional to the growth of myocytes. These studies suggest that timing may be of crucial importance in neonatal cardiac interventions in humans: early definitive repairs of selected congenital heart disease may be more beneficial for the long-term results of surgical treatment.

Species specifics of morphology of the liver of the fishes of the Cyprinidae family

Providing mankind with high-quality products of aquaculture is possible only by introduction of modern industrial technologies to fish farming, growing fish based on modern scientific achievements. Assessment of the ecotoxic situation and identification of impacts of various unfavourable factors of aquatic environment on aquatic organisms should be made through morphological studies of the organs that are first to encounter the impact. The study revealed species specifics of the morphology of the liver of the fishes of the Cyprinidae family – Prussian carp (Carassius gibelio), Eurasian carp (Cyprinus carpio), and bighead carp (Hypophthalmichthys nobilis), which vary by extent of the motor activity in the aquatic environment, nutrition, etc. We determined that during phylogenetic development of fish that grow in the aquatic environment, there occurs a certain restructuring of the liver: the adaptation to various living conditions were accompanied by changes in a number of parameters of macro- and microscopic architectonics of the liver. Cyprinus carpio and Carassius gibelio (omnivores) have a two-lobe liver, while Hypophthalmichthys nobilis (a herbivore) has a three-lobe liver. For C. carpio and H. nobilis, a characteristic feature of the liver was presence of the hepatopancreatitis (the liver and the pancreas, associated into a single organ), and in C. gibelio, they are differentiated into individual organs. A peculiarity of the microscopic structure of the liver of the Cyprinidae family is poorly developed interlobular connective tissue, and parenchyma of the liver lobule has a tubular structure as polyhedral, curved thick-walled tubules, the walls of which are hepatocytes. The greatest amounts of cytoplasm and karyoplasms were seen in C. gibelio, equaling respectively 12.98 ± 1.42 and 0.40 ± 0.02 µm³. The lowest volume of the indicated parameters was in C. carpio, particularly 2.97 ± 0.22 and 0.21 ± 0.01 µm³, respectively. The lowest nuclear-cytoplasmic ratio was observed in hepatocytes of C. gibelio (0.0316 ± 0.0024). The conducted morphological studies at the levels of organs, tissues and cells can reveal how the fishes’ bodies adapt to particular living conditions and impacts of environmental factors.

Genome-Wide Identification and Analysis Uncovers the Potential Role of JAZ and MYC Families in Potato under Abiotic Stress.

As key regulators of the Jasmonates (JAs) signal transduction pathway, JAZ protein, and MYC transcription factors are imperative for plant response to external environmental changes, growth, and development. In this study, 18 StJAZs and 12 StMYCs were identified in potatoes. Their chromosomal position, phylogenetic development, gene structure, and promoter cis-acting parts of the StJAZ genes were analyzed. In addition, Protein-Protein Interaction (PPI) network analysis of StJAZ and StMYC gene families and yeast two-hybrid assay demonstrated that five StMYCs can interact with 16 StJAZs, which provides new insights into the operation mechanism of StJAZs and StMYCs in JA signal response. Moreover, we explored the expression profiles of StJAZs and StMYCs genes in different tissues and during abiotic stresses by RNA-seq data. Based on the PPI network and transcriptome data, the genes StJAZ11, StJAZ16, and StMYC6 were chosen for further qRT-PCR study under salt or mannitol treatment. Under mannitol-induced drought or salinity treatment, the expression patterns of StMYC6, StJAZ11, and StJAZ16 were different, indicating that the JAZ protein and MYC transcription factor may be engaged in the response of potatoes to abiotic stress, which opened up a new research direction for the genetic improvement of potatoes in response to environmental stress.

Phonetic Accommodation During Conversational Interactions: An Overview

During conversational interactions such as tutoring, instruction-giving tasks, verbal negotiations, or just talking with friends, interlocutors’ behaviors experience a series of changes due to the characteristics of their counterpart and to the interaction itself. These changes are pervasively present in every social interaction, and most of them occur in the sounds and rhythms of our speech, which is known as acoustic-prosodic accommodation, or simply phonetic accommodation. The consequences, linguistic and social constraints, and underlying cognitive mechanisms of phonetic accommodation have been studied for at least 50 years, due to the importance of the phenomenon to several disciplines such as linguistics, psychology, and sociology. Based on the analysis and synthesis of the existing empirical research literature, in this paper we present a structured and comprehensive review of the qualities, functions, onto- and phylogenetic development, and modalities of phonetic accommodation.

SARS-CoV-2 evolution among patients with immunosuppression in a nosocomial cluster of a Japanese medical center during the Delta (AY.29 sublineage) surge.

Previous studies have shown that patients with immunosuppression tend to have longer-lasting SARS-CoV-2 infections and a number of mutations were observed during the infection period. However, these studies were, in general, conducted longitudinally. Mutation evolution among groups of patients with immunosuppression have not been well studied, especially among Asian populations. Our study targeted a nosocomial cluster of SARS-CoV-2 infection in a Japanese medical center during Delta surge (AY.29 sublineage), involving ward nurses and inpatients. Whole-genome sequencing analyses were performed to examine mutation changes. Haplotype and minor variant analyses were furtherly performed to detect the mutations on the viral genomes in detail. In addition, sequences of the first wild-type strain hCoV-19/Wuhan/WIV04/2019 and AY.29 wild-type strain hCoV-19/Japan/TKYK15779/2021 were used as references to assess the phylogenetical development of this cluster. A total of 6 nurses and 14 inpatients were identified as a nosocomial cluster from September 14 through 28, 2021. All were Delta variant (AY.29 sublineage) positive. 92.9% of infected patients (13 out of 14) were either cancer patients and/or receiving immunosuppressive or steroid treatments. Compared to AY.29 wild type, a total of 12 mutations were found in the 20 cases. Haplotype analysis found one index group of eight cases with F274F (N) mutation and 10 other haplotypes with one to three additional mutations. Furthermore, we found that cases with more than three minor variants were all cancer patients under immunosuppressive treatments. The phylogenetical tree analysis, including 20 nosocomial cluster-associated viral genomes, the first wild-type strain and the AY.29 wild-type strain as references, indicated the mutation development of the AY.29 virus in this cluster. Our study of a nosocomial SARS-CoV-2 cluster highlights mutation acquisition during transmission. More importantly, it provided new evidence emphasizing the need to further improve infection control measures to prevent nosocomial infection among immunosuppressed patients.

IMAGES OF HUNGER, SATIATION AND THIRST IN THE MIRROR OF ENGLISH AND UKRAINIAN PHRASEOLOGY. Article 3

This publication is the final, third article of the thematic cycle Images of feeding/eating food in the mirror of English and Ukrainian phraseology. It is devoted to the problem of figurative understanding and phraseological description of the processes (including causes and consequences) of CONSUMING food or drinks. The material considered by us offers the possibility of ethnocultural comparative analysis of two unrelated societies — Ukrainian-speaking and English-speaking ones. Based on A. Maslow’s thesis about the basic level of needs in the phylogenetic development of a person as a biological and social being, namely the need to quench hunger and thirst, the phraseological funds of both languages, which are focused on seeing exactly these needs, are considered. It has been proven that phraseological units (PhU) of gustatory semantics verbalize the deep cognitive model AGENT FEEDS THE PATIENT SOMEHOW and its mirror second half PATIENT CONSUMES SOMETHING (FOOD/DRINK) SOMEHOW. This publication highlights exactly this second half of the specified cognitive model. The purpose of this study was to investigate the phraseological fund of a language as certain clots of cultural heritage, cast into a figuratively transformed patterns of idioms, phraseological units, proverbs, sometimes maxims, i.e. prescriptions of ancestors, which they passed on to their descendants regarding the correct worldview and successful functioning in the surrounding world. The total sample is quantitatively distributed unevenly between the two languages, the English component is twice as small as the Ukrainian one: 117 English PhUs and 265 Ukrainian PhU. The semantic component CONSUMPTION is verbalized by 13 verbs in English and 28 in Ukrainian, which indicates a greater sensitivity of Ukrainian speakers to the semantic nuances of the process of consuming food and drinks (them being excessive or insufficient, approved or critically regarded by the speaker who nominates the phenomenon). It was found that the English-speaking sample is more focused on reflecting universal, philosophical aspects of life, while the Ukrainian sample is more “home-centric”, the state of hunger and thirst in the Ukrainian-speaking sample is reflected much more broadly and more emotionally than in the English-speaking sample, overeating is a frequent object of mockery and criticism of Ukrainians, which in no way coincides with the dominant code of political correctness in modern Western culture. The analyzed material testified to a certain role of alcoholic beverages in the lives of representatives of the two ethnic groups, both ethno-specific and cross-cultural customs and traditions were revealed, the presence of English-language PhUs regarding drug use was recorded, which is not observed in Ukrainian-speaking PhUs. In conclusion, let us emphasize that gustatory phraseology of any language reflects not only the processes and customs of FEEDING / CONSUMING something edible, but a much wider spectrum of human existence: personal and social relationships, philosophical interpretations of human needs and limitations, moral prescriptions and prohibitions. In the end, we will repeat the thought of Socrates, with which we started this series of articles: “One must eat to live, not live to eat.”

Analysis of Complete Chloroplast Genome: Structure, Phylogenetic Relationships of Galega orientalis and Evolutionary Inference of Galegeae.

Galega orientalis, a leguminous herb in the Fabaceae family, is an ecologically and economically important species widely cultivated for its strong stress resistance and high protein content. However, genomic information of Galega orientalis has not been reported, which limiting its evolutionary analysis. The small genome size makes chloroplast relatively easy to obtain genomic sequence for phylogenetic studies and molecular marker development. Here, the chloroplast genome of Galega orientalis was sequenced and annotated. The results showed that the chloroplast genome of G. orientalis is 125,280 bp in length with GC content of 34.11%. A total of 107 genes were identified, including 74 protein-coding genes, 29 tRNAs and four rRNAs. One inverted repeat (IR) region was lost in the chloroplast genome of G. orientalis. In addition, five genes (rpl22, ycf2, rps16, trnE-UUC and pbf1) were lost compared with the chloroplast genome of its related species G. officinalis. A total of 84 long repeats and 68 simple sequence repeats were detected, which could be used as potential markers in the genetic studies of G. orientalis and related species. We found that the Ka/Ks values of three genes petL, rpl20, and ycf4 were higher than one in the pairwise comparation of G. officinalis and other three Galegeae species (Calophaca sinica, Caragana jubata, Caragana korshinskii), which indicated those three genes were under positive selection. A comparative genomic analysis of 15 Galegeae species showed that most conserved non-coding sequence regions and two genic regions (ycf1 and clpP) were highly divergent, which could be used as DNA barcodes for rapid and accurate species identification. Phylogenetic trees constructed based on the ycf1 and clpP genes confirmed the evolutionary relationships among Galegeae species. In addition, among the 15 Galegeae species analyzed, Galega orientalis had a unique 30-bp intron in the ycf1 gene and Tibetia liangshanensis lacked two introns in the clpP gene, which is contrary to existing conclusion that only Glycyrrhiza species in the IR lacking clade (IRLC) lack two introns. In conclusion, for the first time, the complete chloroplast genome of G. orientalis was determined and annotated, which could provide insights into the unsolved evolutionary relationships within the genus Galegeae.

Complete chloroplast genomes and comparative analysis of Ligustrum species

In this study, we assembled and annotated the chloroplast (cp) genomes of four Ligustrum species, L. sinense, L. obtusifolium, L. vicaryi, and L. ovalifolium ‘Aureum’. Including six other published Ligustrum species, we compared various characteristics such as gene structure, sequence alignment, codon preference, and nucleic acid diversity, and performed positive-selection genes screening and phylogenetic analysis. The results showed that the cp genome of Ligustrum was 162,185–166,800 bp in length, with a circular tetrad structure, including a large single-copy region (86,885–90,106 bp), a small single-copy region (11,446–11,499 bp), and a pair of IRa and IRb sequences with the same coding but in opposite directions (31,608–32,624 bp). This structure is similar to the cp genomes of most angiosperms. We found 132–137 genes in the cp genome of Ligustrum, including 89–90 protein-coding genes, 35–39 tRNAs, and 8 rRNAs. The GC content was 37.93–38.06% and varied among regions, with the IR region having the highest content. The single-nucleotide (A/T)n was dominant in simple-sequence repeats of the Ligustrum cp genome, with an obvious A/T preference. Six hotspot regions were identified from multiple sequence alignment of Ligustrum; the ycf1 gene region and the clpP1 exon region can be used as potential DNA barcodes for the identification and phylogeny of the genus Ligustrum. Branch-site model and Bayes empirical Bayes (BEB) analysis showed that four protein-coding genes (accD, clpP, ycf1, and ycf2) were positively selected, and BEB analysis showed that accD and rpl20 had positively selected sites. A phylogenetic tree of Oleaceae species was constructed based on the whole cp genomes, and the results were consistent with the traditional taxonomic results. The phylogenetic results showed that genus Ligustrum is most closely related to genus Syringa. Our study provides important genetic information to support further investigations of the phylogenetic development and adaptive evolution of Ligustrum species.
