Survey of Thrips (Thysanoptera) Associated with Four Berry Crops in Mexico1

Abstract Mexico is one of the major exporters of a variety of berries worldwide. Thrips (Thysanoptera) are highly attracted to berry crops, and several species can become serious pests that limit berry yield. Given the pest status of thrips in berry production and the magnitude and importance of berries for export in Mexico, this study was conducted to survey and identify the thrips fauna associated with commercial berry orchards in Mexico. We sampled berry plants in 41 commercial plantations of blackberry (Rubus spp.), blueberry (Vaccinium spp.), raspberry (Rubus spp.), and strawberry (Fragaria × ananasa) in Guanajuato, Jalisco, Michoacán, and Sinaloa during spring and summer 2020. Our study collected 4,394 thrips specimens belonging to 19 species of thrips. Of those, 53.7% were collected from blackberry, 16.1% from blueberry, 15.5% from strawberry, and 14.8% from raspberry. The predominant species in the four berry crops was Frankliniella occidentalis (Pergande). Its relative abundance with respect to other species of thrips collected was 52.9% in blueberry, 69% in raspberry, 79.6% in blackberry, and 88.7% in strawberry. The second most abundant species was Scirtothrips dorsalis Hood, varying from 2.6% in strawberry to 24.6% in blueberry. Other important phytophagous species recorded were Frankliniella cephalica (Crawford) and Frankliniella gossypiana Hood. These four species are invasive, polyphagous, and widespread in Mexico; thus, economic damage by one or more of these species can be expected in locales where management measures are not appropriately applied to avoid economic losses. Data gathered in this survey, coupled with information provided by related studies conducted in Mexico, should serve as a basis for further research dealing with monitoring and management of thrips populations.

Совершенствование технологического цикла клонального микроразмножения Rubus chamaemorus L.

The results of the study of the microclonal propagation of the cloudberry (Rubus chamaemorus L.) of the Leningradskaya and Kondinskaya forms at the stages of microclonal propagation itself and rooting of microshoots in in vitro culture are presented. R. chamaemorus is one of the most popular bog berry plants in the countries of Northern Europe and the northern regions of Russia, possessing highly valuable nutritional and pharmacological properties. In order to intensify industrial berry growing in Russia and meet the market demand for berry products in the context of import substitution, it is necessary to use high-tech methods for obtaining planting material. In order to preserve the valuable gene pool and accelerate the production of a large amount of healthy planting material of R. chamaemorus forms, it is necessary to improve and optimize the technologies or microclonal propagation of this species. The largest number (on average 9.6–9.9 pcs.) and the total length (16.4– 19.5 cm) of R. chamaemorus microshoots in in vitro culture at the stage of microclonal propagation itself have been observed on the Murashige and Skoog culture medium. An increase in the concentration of the “Dropp” preparation from 0.1 to 0.2 mg/l in the culture medium has contributed to an increase in the number of R. chamaemorus microshoots (on average by 1.8–2.4 times), an increase in their total length in the Konsinskaya form (by 1.5 times) and its decrease in the Leningradskaya form (by 1.1 times). The largest number (on average 3.9–4.6 pcs.) and the total length (13.2–14.0 cm) of R. chamaemorus roots at the stage of microshoot rooting in vitro have been noted on the Murashige and Skoog culture medium. An increase in the concentration of indolebutyric acid from 0.5 to 1.0 mg/l in the culture medium has contributed to an increase in the number of R. chamaemorus roots (on average by 1.4 times) and a decrease in their total length (by 1.15–1.25 times).

A Systematic Review of the Beneficial Effects of Berry Extracts on Non-Alcoholic Fatty Liver Disease in Animal Models.

Nonalcoholic fatty liver disease (NAFLD) is the most common cause of chronic liver disease in Western countries and is strongly associated with several metabolic disorders. Plant-derived bioactive extracts, such as berry extracts, with high antioxidant capacity have been used for the treatment and prevention of this pathology. Moreover, they promote circular economy and sustainability. To study the beneficial effects of extracts from different parts of berry plants in animal models of NAFLD. A systematic research of the MEDLINE (via PubMed), Cochrane, and Scopus databases was conducted to identify relevant studies published after January 2011. In vivo animal studies of NAFLD were included in which berry extracts of different parts of the plant were administered and significantly improved altered biomarkers related to the pathology, such as lipid metabolism and hepatic steatosis, glucose and glycogen metabolism, and antioxidant and anti-inflammatory biomarkers. Of a total of 203 articles identified, 31 studies were included after implementation of the inclusion and exclusion criteria. Most of the studies showed a decrease in steatosis and a stimulation of genes related to β-oxidation and downregulation of lipogenic genes, with administration of berry extracts. Berry extracts also attenuated inflammation and oxidative stress. Administration of berry extracts seems to have promising potential in the design of enriched foodstuffs or nutraceuticals for the treatment of NAFLD.

EFFECT OF THE CONCENTRATION OF THE PLANT GROWTH REGULATORS ON IN VITRO SHOOT GROWTH OF BLACKBERRY

Berry fruit species, such as Ribes nigrum, are highly esteemed in numerous countries for their biological and economic value, being regarded as important species of small fruits. Ribes nigrum, indigenous to northern Europe, and northern and central Asia. Conserving species like blackcurrant, as highlighted in the International Scientific reports, is crucial due to their potential health benefits and contributions to maintaining vascular health, especially in postmenopausal populations. The discovery that blackcurrant extract, rich in phytoestrogens, shows promise in preventing elastin degradation and pathological vascular remodeling underscores the importance of preserving this species. In Kazakhstan, the preservation of Ribes nigrum includes various factors, such as ecological significance, local economic value through agriculture, and conservation priorities since blackcurrant plays a significant role in the country's biodiversity and traditional uses. The potential of in vitro propagation for rapid mass production of valuable species is substantial. Our study addresses biodiversity conservation by employing this approach. Specifically, we aimed to investigate the impact of nutrient media and growth regulators on shoot multiplication of Ribes nigrum. Our findings reveal that the optimal concentration of plant growth regulators (PGR) significantly influences both the number and length of shoots. Notably, the highest multiplication rate for Ribes nigrum was achieved on MS with a combination of BAP at 0.5 μ/L and GA 0.5 μ/L. In conclusion, our study elucidates the effects of manipulating PGR concentrations in culture media on Ribes nigrum. We recommend optimizing these concentrations to enhance the growth of Ribes nigrum for potential reintroduction efforts and biodiversity conservation. The research is being conducted as part of program BR21882166, which focuses on the scientific and practical aspects of reproducing, conserving, and utilizing fruit and berry plants from the natural flora of Western, Eastern, Central, and Northern Kazakhstan to ensure food security. This program is financially supported by the Ministry of Science and Higher Education of the Republic of Kazakhstan for the period 2023-2025.

Identification and characterization of the causal agent of powdery mildew on native salmonberry and thimbleberry plants in British Columbia

Salmonberry (Rubus spectabilis) and thimbleberry (Rubus nutkanus) are important native berry plants for Indigenous communities and restoration sites in the coastal region of British Columbia (BC). Compared to cultivated berry plants, information on the diseases impacting native berry plant species is limited. In late August 2022, powdery mildew symptoms and signs were observed on field plots of salmonberry and thimbleberry plants at the Agassiz Research and Development Centre, BC. The disease symptoms progressed until the end of September. The morphology of conidiophores and conidia when examined under a compound and scanning electron microscope showed they matched with those of Podosphaera aphanis. DNA from diseased foliage was subjected to PCR amplification with primers representing the internal transcribed spacer (ITS) region of rDNA followed by sequencing. The corresponding sequences from both hosts showed >99% similarity to P. aphanis in GenBank and grouped with several accessions of P. aphanis following phylogenetic analysis. In artificially inoculated trials conducted in the greenhouse, powdery mildew symptoms developed within 3−4 weeks post-inoculation and P. aphanis isolates from salmonberry and thimbleberry were cross-pathogenic to each host. To our knowledge, this is the first study characterizing the powdery mildew pathogen infecting salmonberry and thimbleberry and demonstrating cross-pathogenicity to both hosts. The outcomes from this study provide insight into the biology of the powdery mildew pathogen infecting native Rubus spp.

Functional responses of two species of predatory mites (Acari: Phytoseiidae) to eggs and first-instar nymphs of Bactericera Gobica Logniova (Homoptera: Psyllidae).

The goji berry psyllid, Bactericera gobica Logniova (Homoptera: Psyllidae), is one of the most important pests on goji berry plants (Lycium barbarum L.), whose fruits are widely used in traditional Chinese medicine and food. However, chemical control is still the predominant control strategy of this pest. Recently, two species of predatory mites, Neoseiulus setarius Ma, Meng & Fan and Neoseiulus barkeri Hughes were found to be associated with B. gobica in China. To assess their predation potential against B. gobica, the functional responses of these two phytoseiid species feeding on different densities (2, 4, 8, 12, 16, 24 and 32 individuals) of B. gobica eggs and 1st instar nymphs were compared at a temperature of 25ºC ± 1º C. Logistic regression analysis revealed that both predatory mite species exhibited type Holling-II functional responses on eggs and 1st instar nymphs of B. gobica, with the predation number increased for both predators as the density of prey increased. Overall, N. setarius consumed more prey compared to N. barkeri across all levels of prey densities. Meanwhile, the highest attack rate (α = 0.0283), the lowest handling time (Th = 1.1324h prey- 1), and the highest estimated maximum predation rate (T/Th = 21.19 prey day- 1) were all observed for N. setarius fed with 1st instar nymphs of B. gobica. These findings suggest that it is worthy considering utilizing N. setarius and N. barkeri as candidate biocontrol agents of B. gobica, with N. setarius appearing to be a more effective predator than N. barkeri.

New productive pear variety Favoritka

The results of the selection and variety study of pears in the conditions of the Southern Urals are considered. At the South Ural Research Institute of Horticulture and Potato Growing, a branch of the Federal State Budgetary Institution Urfanits Ural Branch of the Russian Academy of Sciences, breeding work was carried out to improve the assortment of pears for the Ural region. As a result of many years of breeding work, the range of fruit and berry plants was replenished with a new pear variety, Favoritka, which in 2022 was included in the State Register of Breeding Achievements approved for use. In the process of breeding work, the winter hardiness of pear varieties in the harsh climatic conditions of the Chelyabinsk region was studied, as a result it was noted that infield conditions when the temperature dropped to -40 ° C, freezing of trees of local varieties did not exceed 1 point. An assessment was made of the yield of local varieties, among which the following varieties stand out: Vekovaya, Myth, Favoritka, and Zolotoy Shar, with an average yield of 24 - 28 kg per tree. The economic indicators of the Favoritka pear variety (profitability level of 253.5%) indicate its suitability for cultivation in both industrial and amateur gardening in the Ural region. A pomological description and assessment of the economic usefulness of the new Favoritka pear variety are presented, which combines large fruit (fruit weight can reach 340 g), high winter hardiness, productivity, resistance to abiotic and biotic stressors (not affected by scab, resistant to pear gall mite), has fruits of excellent taste, suitable for fresh consumption, as well as for processing (preparing jams, preserves, compotes, etc.). The variety is in demand among the population and is of interest as a source of giant fruit in further breeding work.

Arthrocladiella mougeotii Causing Powdery Mildew on Goji Berry Plants (Lycium barbarum and L. chinense) and Mixed Infections with Phyllactinia chubutiana in California.

Goji berries (Lycium barbarum and L. chinense) have a rich historical significance in traditional Chinese medicine and have gained popularity as a superfood in Western cultures. From 2021 to 2023, powdery mildew was observed on goji plants of both species in community and residential gardens in Yolo County, California (U.S.A.). Disease severity varied from 20 to 100% of infected leaves per plant. Powdery mildew was characterized by the presence of white fungal colonies on both sides of leaves and fruit sepals. Additionally, a brownish discoloration was observed in infected mature leaves, resulting in further defoliation. Morphologically, the fungus matched the description of Arthrocladiella mougeotii. The pathogen identity was confirmed by phylogenetic analyses of the rDNA internal transcribed spacer and the 28S rDNA gene sequences. Pathogenicity was confirmed by inoculating healthy L. barbarum plants using infected leaves and successfully reproducing powdery mildew symptoms after 28 days (22°C, 60% RH), with A. mougeotii colonies confirmed by morphology. Control leaves remained symptomless. Coinfection with Phyllactinia chubutiana was detected on plants from two separate gardens, with A. mougeotii observed first in late spring (May to June) and P. chubutiana later in the summer (July to August). These results revealed that both A. mougeotii and P. chubutiana constitute causal agents of powdery mildew on goji berry plants, often infecting the same plant tissues simultaneously. To our knowledge, this is the first report of A. mougeotii causing powdery mildew on L. barbarum and L. chinense in California, which provides a better understanding of the etiology of powdery mildew of goji plants.

Drivers of the Sisrè berry plant [Synsepalum dulcificum (Schumach & Thonn.) Daniell] rhizosphere bacterial communities in Benin

Each plant species has its own rhizobacteriome, whose activities determine both soil biological quality and plant growth. Little knowledge exists of the rhizosphere bacterial communities associated with opportunity crops with high economic potential such as Synsepalum dulcificum. Native to West Africa, this shrub is famous for its red berries representing the only natural source of miraculin, a glycoprotein, with sweetening properties, but also playing a role in the treatment of cancer and diabetes. This study aimed to characterize the structure and diversity of rhizobacterial communities associated with S. dulcificum and to identify the parameters determining this diversity. An initial sampling stage allowed the collection of rhizosphere soils from 29 S. dulcificum accessions, belonging to three distinct phenotypes, from 16 municipalities of Benin, located either on farms or in home gardens. The bacterial diversity of these rhizosphere soils was assessed by Illumina sequencing of the 16S rRNA gene after DNA extraction from these soils. Furthermore, an analysis of the physicochemical properties of these soils was carried out. All accessions combined, the most represented phylum appeared to be Actinobacteriota, with an average relative abundance of 43.5 %, followed by Proteobacteria (14.8 %), Firmicutes (14.3 %) and Chloroflexi (12.2 %), yet the relative abundance of dominant phyla varied significantly among accessions (p < 0.05). Plant phenotype, habitat, climate and soil physicochemical properties affected the bacterial communities, but our study pointed out that soil physicochemical parameters were the main driver of rhizobacterial communities' structure and diversity. Among them, the assimilable phosphorus, lead, potassium, arsenic and manganese contents, texture and cation exchange capacity of rhizosphere soils were the major determinants of the composition and diversity of rhizosphere bacterial communities. These results suggested the possibility of improving the growth conditions and productivity of S. dulcificum, by harnessing its associated bacteria of interest and better managing soil physicochemical properties.

ДИКОПЛОДОВЫЕ ПОРОДЫ НА НАРУШЕННЫХ ЗЕМЛЯХ СЕВЕРНОГО КАВКАЗА

Wild fruit species on disturbed lands grow in degraded areas and have the ability to quickly restore the ecosystem. Restoration of disturbed lands in mountain and piedmont areas plays a big role and is a significant resource in the national economic potential of the region, an important reserve for agricultural production. The article provides an overview of the disturbed lands of the North Caucasus as a result of mining. For the purpose of biological rehabilitation, a classification of technogenic landscapes has been developed. The state of wild fruit and berry plants in disturbed areas has been revealed, which depends on the types of substrate, topography, climate, parts of the slopes and their steepness. Eleven wild fruit species grow naturally in quarries in the study region. Among them, sea buckthorn and dog rose stand out. They tolerate drought well and are resistant to low soil fertility. Cherry plum, common hazel and hawthorn prefer better moisture conditions. The degree of root growth in different parts of the slope has been established, which makes it possible to determine the suitability of soil and hydrological conditions for wild fruit species and to plan appropriate measures. It has been confirmed that the moist parts of the lower slopes are the most favorable for the growth and development of plants. The individuality of the formation of wild fruit and berry plantings according to the exposures at each deposit separately is noted. The prospects of wild fruit breeds capable of producing root shoots are substantiated. It was revealed that the spread of root suckers occurs more intensively on light soils, despite the fact that moisture is better on clay; this is not the main criterion for the spread of suckers. An assortment of wild fruit plants has been developed to create protective plantings in various environmental conditions. Measures are proposed to restore disturbed lands. Key words: WILD FRUIT SPECIES, DISTURBED LANDS, SLOPE, QUARRY, REHABILITATION, ROOT OFFSPRING, ASSORTMENT

Study on Morphological Traits of Natural Populations of Vaccinium uliginosum at Different Altitudinal Gradients on Changbai Mountain

Vaccinium uliginosum (VU) is one of the most precious wild berry plants distributed in the Changbai Mountain region in northeast China. Eight key morphological traits of VU were analyzed to examine the variation among and within five natural populations at different altitudes, as well as their response to environmental factors. The study results showed an increasing trend of variation among populations with ascending altitudes, but the range variation within populations exhibited a decreasing trend. The diversity level among populations was found to be higher than that within populations, and the five populations of VU were classified into four groups. Except for leaf width and twig length, all other morphological traits demonstrated significant or extremely significant correlations. Generally, with increasing altitude, leaf length decreased, while plant height, clear bole height, and basal diameter decreased significantly, and similar trends were observed with moisture factors, while a significant positive correlation was found with temperature factors. Among them, the morphological traits of clear bole height and basal diameter exhibited the strongest correlation with environmental factor variations. Overall, these findings indicate extensive variation in the morphological traits of VU within and among populations at different altitudes, with clear responses to changes in environmental factors.

Climate and land‐use change impacts on cultural use berries: Considerations for mitigative stewardship

Societal Impact StatementCultural use berries are prized foods and medicines across the United States and Canada, with almost 200 different species used by Indigenous Peoples. Berries are increasingly being impacted by environmental and land‐use change. Berry habitats, how and when berry plants reproduce, and the volume of berries available for harvest each year are shifting widely. These changes are impacting access to, availability of, and consumption of berries. Biocultural stewardship practices, like low‐intensity fire, transplanting, and thinning, can be used in response to these stressors to support berry plant health and productivity as well as a sustained relationship with this important food.SummaryAlmost 200 different species of berries are used for food and medicine by Indigenous Peoples, with unparalleled nutritional and cultural significance among plant foods. Environmental and land‐use change is increasingly compromising access to, availability of, and consumption of berries. In this review, I consider (a) how climate and land‐use change are impacting cultural use berries across species and places, as documented by Indigenous Peoples and in the scientific literature, and (b) how stewardship practices are being applied to promote resilience and sustainability in berrying landscapes experiencing stress. Climate impacts on Arctic and subarctic berry species include earlier ripening, changes in taste, or increased variability in abundance. These same regions are experiencing a proliferation of shrubs, while forests throughout the lower 48 and Canada are suffering from suffocating fuel loads and stand densities that are not conducive to berry habitat for many species. In the Pacific West, berries are influenced by prolonged droughts and increasing spring and summer temperatures. Climate change impacts are amplified by shifts in land use for forestry and agriculture. Biocultural stewardship practices, like low‐intensity fire, thinning, transplanting, and cultural care, can be used to mitigate these impacts and promote berry microclimate habitats. There is opportunity for intertribal networking and knowledge sharing around berry stewardship practices that will support local and regional climate change responses.

Predicting the suitable habitat distribution of berry plants under climate change

ContextClimate change is altering suitable habitat distributions of many species at high latitudes. Fleshy fruit-producing plants (hereafter, “berry plants”) are important in arctic food webs and as subsistence resources for human communities, but their response to a warming and increasingly variable climate at a landscape scale has not yet been examined.ObjectivesWe aimed to identify environmental determinants of berry plant distribution and predict how climate change might shift these distributions.MethodsWe used species distribution models to identify characteristics and predict the distribution of suitable habitat under current (2006–2013) and future climate conditions (2081–2100; representative concentration pathways 4.5, 6.0, & 8.5) for five berry plant species: Vaccinium uliginosum L., Empetrum nigrum L., Rubus chamaemorus L., Vaccinium vitis-idaea L., and Viburnum edule (Michx.) Raf..ResultsElevation, soil characteristics, and January and July temperatures were important drivers of habitat distributions. Future suitable habitat predictions showed net declines in suitable habitat area for all species modeled under almost all future climate scenarios tested.ConclusionsOur work contributes to understanding potential geographic shifts in suitable berry plant habitat with climate change at a landscape scale. Shifting and retracting distributions may alter where communities can harvest, suggesting that access to these resources may become restricted in the future. Our prediction maps may help inform climate adaptation planning as communities anticipate shifting access to harvesting locations.

The article presents the results of work on the formation of a bioresource collection of berry plants of the Russian State Agrarian University – Moscow Timiryazev Agricultural Academy based on a variety testing area of forest berry plants and a collection of species of the Dendrological Garden named after R.I. Schroeder. The variety testing area includes berry plants of the genera Vaccinium (V. corymbosum – 8 species; V. angustifolium – 4 species; V. corymbosum × V. angustifolium – 3 species; V. oxycoccos – 2 species; V macrocarpon – 3 species; V. vitis-idaea – 4 species) and Rubus (R. arcticus – 9 species; R. chamaemorus – 1 species). Introduced berry plants with edible fruits from the 24 genera are mainly represented in the collection of the Dendrological Garden named after R.I. Schroeder: Actinidia (4 species), Amelanchier (5 species), Aronia (2 species), Berberis (2 edible species), Cornus (2 species), Crataegus (more than 10 species), Elaeagnus (2 species), Fragaria (2 species), Hippophae (1 species), Lonicera (1 edible species), Mahonia (1 species), Morus (2 species), Prunus (13 species), Ribes (4 species), Rosa (6 edible species), Rubus (6 species), Sambucus (1 edible species), Schisandra (1 species), Shepherdia (1 species), Sorbus (more than 10 more than 10 species and a number of cultivars and a number of cultivars), Vaccinium (wild forms of 5 species), more than 5 species), Vitis (3 species). All plants included in the bioresource collection have nutritional and medicinal value and are quite stable in growth, development and fructification in the Moscow microclimate. Work has begun on the creation of an in vitro genetic bank of economically valuable, rare and difficult to propagate species, varieties and forms of berry plants. The aim is to maintain a bioresource collection, preserve biological diversity and accelerate the cultivation of planting material with subsequent fruit production under conditions of import substitution.

Comprehensive safety assessment of serendipity berry sweet protein produced from Komagataella phaffii

Serendipity berry plant (Dioscoreophyllum cumminsii (Stapf) Diels) is the source of a naturally sweet protein referred to as monellin. The safety of serendipity berry sweet protein (SBSP) containing single polypeptide monellin (MON) expressed in Komagataella phaffii (formerly Pichia pastoris) and produced via precision fermentation was examined comprehensively through assessments of in vitro and in silico protein digestion, in silico allergenicity, in vitro genotoxicity (reverse mutation and mammalian micronucleus assays), and 14-day and 90-day oral (dietary) toxicity studies in rats. There was no indication of allergenicity for SBSP in the in silico analyses. Results from both in vitro and in silico protein digestibility assessments indicated that SBSP is digested upon ingestion and would therefore be unlikely to pose a toxigenic or allergenic risk to consumers. SBSP was non-genotoxic in in vitro assays and showed no adverse effects in the 14-day or 90-day toxicity studies up to the highest dose tested. The 90-day toxicity study supports a NOAEL for SBSP of 1954 mg/kg bw/day, which corresponds to a NOAEL for MON of 408 mg/kg bw/day.

Identification and characterization of a novel Cytorhabdovirus associated with goji berry (Lycium barbarum L.) crinkle disease.

Goji berry (Lycium barbarum L.) is a traditional Chinese herbal medicinal plant that is extensively cultivated in the arid and semiarid regions of northwest China. In this study, a novel cytorhabdovirus, tentatively named "goji cytorhabdovirus A (GCVA)," was identified from the goji berry plant exhibiting leaf crinkle symptoms through high-throughput sequencing (HTS). GCVA contains a linear, negative sense single-stranded RNA genome of 14,812 nucleotides and encodes six open reading frames in the order of 3' leader-N-P-P4-M-G-L-5' trailer. The genome of GCVA shares the highest nucleotide (nt) identity of 65.80% (16% query coverage) with yerba mate virus A (YmVA) (NC_076472). The N and L proteins also share low amino acid (aa) identities (<35.42 and < 41.23%, respectively) with known cytorhabdoviruses. Typical features of the viruses in the genus Cytorhabdovirus include a highly conserved consensus sequence in the intergenic regions and extensive complementation of the 5' non-coding trailer and the 3' leader. These features were also found in GCVA. These data in combination with a phylogenetic analysis that was based on the aa sequences of the N and L proteins support the proposal that GCVA is a new species in the genus Cytorhabdovirus.

FEATURES OF ELEMENTS ACCUMULATION IN FRUIT AND BERRY PLANTS CULTIVATED IN THE VICINITY OF ZELENOGORSK CITY, KRASNOYARSK REGION

The aim of the study is to identify the peculiarities of the elemental composition of berries (fruits) and leaves of raspberry (Rubus idaeus L.), rowan (Sorbus aucuparia L.), black currant (Ribes nigrum L.), sour cherry (Cerasus vulgaris L.), serviceberry (Amelanchier ovalis Medik.) collected in the vicinity of Zelenogorsk, Krasnoyarsk Region, with an assessment of their potential use as sources of elements, ecological safety of use, as well as patterns of distribution of elements between plants, soil, and the surrounding environment. The elemental composition was analyzed using the method of arc atomic emission spectroscopy with a multi-channel analyzer of emission spectra (DAES with MAES) after ashing. As a result, the presence of 30 elements was determined in the ash of the studied plants, 25 of which belong to trace elements, and 22 are (conditionally) essential. The belongingness of the minimum extremes of content to mostly odd ordinal numbers of elements in the Mendeleev table was established, while the maximum extremes belonged to even ones. It is proposed to represent the revealed regularities in the form of combinations of extrema with the corresponding serial numbers of atoms, which clearly indicates the plant's ability to concentrate certain chemical elements. Based on the degree of accumulation from the soil, which indicates the ability of plants to accumulate elements, the highest indicator for all studied species and their raw materials is K, for all raspberry and blackcurrant raw materials – Ca, for cherry and raspberry leaves with berries (fruits) and separately for cherry fruits – Mg, only for blackcurrant leaves with berries (fruits) – Ti, for blackcurrant leaves with berries (fruits) – Sr and Ag. The study identified only Ti and Ag as having a "strong accumulation" in the biological absorption of elements, while the others were common for vegetation. Raspberry was found to have the highest biogeochemical activity among the studied fruit and berry plants (regardless of the raw material), followed by blackcurrant. It is shown that the raw materials "leaves + berries (fruits)" in all the studied cases contain much more trace elements, in contrast to individual berries (fruits). The study demonstrated the potential use of these plant species as sources of macroelements and trace elements, including essential ones.
