Genetic diversity and phylogenetic analyses of Turkish sweet corn (Zea mays var. saccharata) varieties using ISSR markers and chloroplast trnL-F IGS region

Genetic diversity levels are critical for characterizing and utilizing germplasm collections and for making improvements related to elite germplasms. The current study investigated the genetic diversity level and phylogenetic relationships in ten Turkish sweet corn varieties (Zea mays var. saccharata) using 15 ISSR markers and trnL-F intergenic spacer regions, respectively. A total of 75 loci were identified, of which 57 (76%) were polymorphic. The highest polymorphism ratio (100%) was found using UBC811, UBC817, and UBC823 ISSR markers, while the lowest ratio (45.4%) was identified using UBC829. According to trnL-F intergenic spacer region analyses, nucleotide diversity was found as π: 0.030 for Nei and θ: 0.036 for Watterson, respectively. In trnL-F intergenic spacer regions, several polymorphic (variable) sites were identified 28 of which 57% (16/28) were parsimony informative sites and 399 sites were invariable (monomorphic). The phylogenetic analysis revealed that two major groups were observed named groups A and B and ten sweet corn genotypes clustered along with known maize genotypes in subgroup B2 with 98% bootstrap value. Consequently, the ISSR data obtained in this study revealed that Turkish sweet corn genotypes exhibit extensive genetic diversity, and the trnL-F intergenic spacer region was successfully utilized to differentiate between maize genotypes from various origins and whole plant taxa.

Morphological characteristics, genetic diversity, and ethnobotanical uses of Citrus hongheensis (Rutaceae), an endangered species

The species Citrus hongheensis is an endangered species and the most primitive Citrus species with the most developed winged leaves. It is endemic to south Yunnan Province, southwest China, and only distributed in a very narrow area along the south bank of the Honghe river (the Yuanjiang river). By combining ISSR and morphological data from 11 populations, it shows that the species has rich genetic diversity among and within populations although the population is declining gradually. According to field and market surveys, the local Hani people have traditionally used C. hongheensis for a long time, such as the dried young fruits of the species as Chinese traditional medicine, leaves as food spice, as well as other organs. By collecting all existing knowledge of traditional and present uses, as well as further potential uses, we demonstrate that the species has good development prospects. Based on rich diversity, ethnobotanical uses, and a positive cultural environment, it was decided to choose four populations (YJNNDM, LCDX, HHDYJ, and YJYJYJ) of C. hongheensis for in situ conservation and artificial sexual reproduction. This will allow to develop new uses of the species, while providing indications for the conservation of other endangered species.

Assessing genetic diversity of berberis genotypes selected from an F1 population using molecular markers

Barberries are versatile shrubs with diverse applications, including ornamental, medicinal, and edible purposes. In this study, we employed molecular markers to assess the genetic diversity and genetic base of superior barberry genotypes selected from an F1 population obtained through Shahrood University Barberry Breeding Program (SUBBP), alongside their parents. We utilized nine ISSR markers and 10 RAPD markers to analyze the population’s genetic diversity. From these markers, we obtained 98 polymorphic bands using ISSR markers and 112 polymorphic bands using RAPD markers. The average PIC value was 0.16 for ISSR markers and RAPD markers, while the average genetic resolution power was 3.93 for ISSR markers and 2.11 for RAPD markers. Furthermore, we calculated the genetic dissimilarity coefficient (GDC) based on ISSR and RAPD markers, which ranged from 0.23 to 0.86 (average 0.62) and 0.21 to 0.85 (average 0.60), respectively. The ISSR data analysis classified the genotypes into three main clusters, with genotypes 0515, R5N1, ‘Bth’, ‘Seedless (BD)’, and R2N1 being genetically distant from the others. Similarly, the analysis of 10 RAPD primers resulted in the classification of genotypes into three main groups. Notably, genotype 0609 exhibited greater genetic distance from other genotypes in this subgroup. The Principal Coordinates Analysis (PCoA) using both ISSR and RAPD marker data further supported the grouping of genotypes into three distinct clusters. These results provide valuable insights into the genetic composition of the F1 population and contribute to the advancement of barberry breeding strategies.

Comprehensive assessment of genetic variation in native heterostylous primrose genotypes of Türkiye

Primula vulgaris L. is an essential species of ornamental plant value with attractive flowers distributed in humid and cold regions. It spreads around Giresun, Gümüşhane, Trabzon, and Rize in Türkiye’s Eastern Black Sea region. Through molecular and morphological markers, this study determined the genetic diversity and similarity levels of Primula genotypes sampled from different areas (Samsun, Trabzon, Ordu, and Giresun). Variation was determined regarding morphological characteristics, and that plant shape, flower, and leaf properties were highly variable. Molecular data support morphological features. Thirteen ISSR primers determined the dimensions of genetic diversity, and the genotypes’ similarity indexes were between 0.70 and 0.92. It is seen that there is no clustering in the two- and three-dimensional graphics created in line with the genetic parameters, and the genotypes are distributed. Also, plant characteristics were correlated with the ISSR data, and many DNA profiles were detected. This study has characterized Primula genotypes that naturally spread in the Black Sea region of Türkiye. It is a guiding study for transferring some observed properties to culture varieties.

Morphological, pathogenic and genetic diversity in Diplodia seriata associated with black rot canker of apple in India

Apple cankers are extremely destructive diseases threatening the global apple industry through direct and indirect losses. The population structure of the pathogens is of paramount significance for the development of efficient management strategies. Therefore, phenotypic, pathogenic, and genetic diversity of Diplodia seriata causing black rot canker of apple was investigated in this study. All the isolates were included for investigating the in vitro mycelial growth, conidial dimensions, and pathogenic variability on two-year-old potted apple seedlings. The ISSR approach was used to investigate the molecular diversity of D. seriata. Mycelial growth rates were found to vary significantly amongst the isolates; however, there were no major variations seen between the different geographical groupings of isolates. Pathogenicity tests revealed variations in the size of cankers among the isolates indicating the presence of virulence variability. The isolates were segregated into three virulence groups based on canker length. The Bayesian analyses of ISSR data divided the isolates into two genetic clusters. The genetic clustering of the isolates revealed no relationship with geographical origin of the isolates. Furthermore, no direct relationship of genetic clustering was observed with morphological or pathogenic variability. The ISSR primers revealed very high level of variability in D. seriata; however, no distinct populations of the pathogen existed which is an indication of high level of gene flow between the diverse geographical populations. According to our knowledge, this is the first thorough investigation on the diversity of D. seriata associated with apple black rot canker in India.

MOLECULAR MARKER BASED ESTIMATION OF APRICOT GENOTYPES COLLECTED FROM YEŞİLHİSAR REGION OF KAYSERİ

Apricot is one of the most important stone fruits in the world. It can be evaluated as both fresh consumption and drying. Turkey is the first apricot producing country and has a rich genetic diversity. There are many apricot populations in different regions of Turkey. Some of them contain standard cultivars and some of them consist of local varieties or genotypes. Kayseri province has relatively important local apricot populations. In this study, genetic diversity in apricot populations in Yeşilhisar, Kayseri-Turkey was investigated. In the study, 32 apricot genotypes were studied with ISSR and POX markers. In apricot genotypes, 88.1% polymorphism was obtained with ISSR markers and 32.7% with POX markers. A dendrogram was created by combining ISSR and POX markers data. Accordingly, the level of similarity among genotypes varied between 0.73-1.00. Among the apricots, the genotypes 31 and 32 in particular were clearly apart from the others. In addition, genotype 21 was located alone in the dendrogram. The remaining apricots are divided into two main groups. The study revealed that Yeşilhisar region apricots have a significant variation.

Genetic diversity analysis in wheat cultivars using SCoT and ISSR markers, chloroplast DNA barcoding and grain SEM

BackgroundWheat is a major cereal that can narrow the gap between the increasing human population and food production. In this connection, assessing genetic diversity and conserving wheat genetic resources for future exploitation is very important for breeding new cultivars that may withstand the expected climate change. The current study evaluates the genetic diversity in selected wheat cultivars using ISSR and SCoT markers, the rbcL and matK chloroplast DNA barcoding, and grain surface sculpture characteristics. We anticipate that these objectives may prioritize using the selected cultivars to improve wheat production. The selected collection of cultivars may lead to the identification of cultivars adapted to a broad spectrum of climatic environments.ResultsMultivariate clustering analyses of the ISSR and SCoT DNA fingerprinting polymorphism grouped three Egyptian cultivars with cultivar El-Nielain from Sudan, cultivar Aguilal from Morocco, and cultivar Attila from Mexico. In the other group, cultivar Cook from Australia and cultivar Chinese-166 were differentiated from four other cultivars: cultivar Cham-10 from Syria, cultivar Seri-82 from Mexico, cultivar Inqalab-91 from Pakistan, and cultivar Sonalika from India. In the PCA analysis, the Egyptian cultivars were distinct from the other studied cultivars. The rbcL and matK sequence variation analysis indicated similarities between Egyptian cultivars and cultivar Cham-10 from Syria and cultivar Inqalab-91 from Pakistan, whereas cultivar Attila from Mexico was distinguished from all other cultivars. Combining the data of ISSR and SCoT with the rbcL and matK results retained the close resemblance among the two Egyptian cultivars EGY1: Gemmeiza-9 and EGY3: Sakha-93, and the Moroccan cultivar Aguilal, and the Sudanese cultivar El-Nielain and between Seri-82, Inqalab-91, and Sonalika cultivars. The analysis of all data distinguished cultivar Cham-10 from Syria from all other cultivars, and the analysis of grain traits indicated a close resemblance between cv. Cham-10 from and the two Egyptian cultivars Gemmeiza-9 and Sakha-93.ConclusionsThe analysis of rbcL and matK chloroplast DNA barcoding agrees with the ISSR and the SCoT markers in supporting the close resemblance between the Egyptian cultivars, particularly Gemmeiza-9 and Sakha-93. The ISSR and SCoT data analyses significantly expressed high differentiation levels among the examined cultivars. Cultivars with closer resemblance may be recommended for breeding new wheat cultivars adapted to various climatic environments.

Genetic resources diversity of tea (Camellia sinensis (L.) Kuntze) in the southern region of the Caspian Sea

AbstractIn the fields of agricultural, food and medical research, the potential impacts of tea on human health are of special interest because tea (Camellia sinensis (L.) Kuntze) is continuously consumed by many people in the world. The evaluation of the diversity of genotypes found in tea germplasm can aid in the improvement of the breeding programme. In this study, the genetic diversity of 30 tea genotypes from two commercial sites of tea production in Iran was investigated by using morphological and 12 ISSR markers. Morphological analysis showed that the diversity between samples of tea was limited, and the narrow matching range was calculated. In cluster analysis at level 0.63, samples were divided into four groups. The application of 12 ISSR primers produced 91 polymorphic bands. PIC test showed a range of 0.41–0.48. Based on the ISSR data, the matching range was obtained in the range of 0.24–0.93. In cluster analysis, samples at level 0.58 were divided into five groups. According to the results, it can be understood that these series of traits and primers can very well recognize genetic differences. Using these markers, genetic diversity was observed among tea genotypes, but this diversity was not such as to be able to separate genotypes of various regions from each other. The results showed that the tea genotypes in Iran had high genetic diversity. As a consequence, the findings of our study will help the development of tea germplasm conservation strategies and their sustainable use in breeding programmes.

Agronomic, Physiological, Genetic and Phytochemical Characteristics of Onion Varieties Influenced by Daylength Requirements

The evaluation of A. cepa biodiversity provides onion breeders with great prospects to obtain plants with high resistance to environmental factors, remarkable yield, and product quality. Genetic diversity assessment of a collection of nine short- and long-day onion landraces and varieties originated from different Iranian regions, using ISSR markers and UPGMA dendrograms, was carried out for the first time. Short-day landraces (Sarze, Sarkoreh, and Kerman) originated from low latitude and short-day hybrids (Mirela and Soberana) demonstrated high genetic similarity, in terms of physiological responses to day length and temperature during the crop cycle and bulbing stage initiation. Contrarily, high latitude landraces (Azarshahr, White Gorgan, Kurdistan, and Esfahan) showed low biometrical, agronomic and genetic similarity with commercial short-day onions. Specific differences in morphological reactions between these two groups displayed diverse responses of plants to day length and temperature. Long- and short-day cultivars displayed significant differences in the dynamics of leaf and scale number, leaf and root length, dry and fresh weight, and bulbing ratio and bulb diameter, which were in accordance with ISSR data. The local landraces Azarshahr, Kurdistan, and Esfahan had high antioxidant status, suggesting high prospects for their utilization as an alternative to foreign F1 hybrid varieties.

Assessing Morphological Species and Interspecific Relationships in North American Grapeferns (Sceptridium; Ophioglossaceae) Using ISSR Markers

Abstract— Relationships among North American Sceptridium (sensu Škoda) species are often difficult to assess because of few stable distinguishing characters and high intraspecific variability. We used ISSR-PCR to examine relationships among four samples of Holubiella, 24 samples representing four diploid North American Sceptridium species, and a Russian Sceptridium sample. Nine ISSR primers yielded 147 polymorphic loci. We generated three neighbor-joining dendrograms using a Jaccard, Nei & Li, or Dice coefficient. All three coefficients cluster based solely on the presence of bands and not the absence. ISSR data analyses across all three coefficients were consistent with published analyses of DNA sequence data in supporting Holubiella as sister to all Sceptridium species sampled. Sister group relationships among the four Sceptridium species were not consistent across all three neighbor-joining analyses, and bootstrap support was generally low. However, 26 of the 29 samples consistently clustered with other samples of similar morphology, and these clusters generally supported current species concepts. In taxa such as Sceptridium, with low DNA sequence variability among species, ISSR-PCR may provide an important tool for evaluating morphologically defined species, but additional data are necessary for establishing robust hypotheses of phylogenetic relationships.

THE ANALYSIS OF DNA BARCODING AND THE EVOLUTIONARY DIVERGENCE OF ANNONA BY ISSR MARKERS

The genus Annona includes important commercially grown tropical crops but also has been grown popularly in Vietnam due to its wide range of clinical applications. In this study, two DNA barcodes (rbcL and rpoC1) and two ISSR markers were used to assess the interspecies of eleven Annona samples collected from different provinces in the Mekong Delta. As a result, the rbcL marker was successfully amplified and sequenced for identifying Annona species, while rpoC1 sequences required extensive editing and could not distinguish between A. muricata, A. glabra, and A. squamosa samples in BLASTN analysis. The rbcL and rpoC1 sequences harbor 9 and 7 SNPs, respectively, and showed cross evolution properties of A. squamosal NDL-NB among three species. The phylogenetic analysis revealed that sample NDL-NB, previously recognized as A. squamosa morphologically, was grouped in the cluster of A. muricata based on rbcL sequences, whereas it was distinguished in the clusters of A. squamosal and A. glabra based on rpoC1 sequences. Among 33 bands generated from ISSR primers, 20 bands were polymorphic, accounting for 60.60%. Dendrogram analysis of ISSR data could classify seven amplified DNA samples into three genotypes that were not geographically dependent. In conclusion, the performance of the approved DNA barcodes and ISSR analysis appeared to be species-specific or genus-specific, especially indicating the evolutionary divergence of Annona species derived from a neighboring country and its adaptation to certain geographical locations.

Genetic diversity of Iranian populations of Pyrenophora graminea, the causal agent of leaf stripe disease on barley

AbstractLeaf stripe disease caused by Pyrenophora graminea is an economically significant disease of cultivated barley worldwide, including Iran. Considering economic impact of this disease on barley industry in Iran, in this study genetic diversity of P. graminea populations mainly collected from barley (229 isolates) in different regions of East Azerbaijan Province was examined using ISSR and RAPD molecular markers. The average polymorphic information content (PIC) values for ISSR and RAPD were 0.28 in both markers, and a significant correlation was observed between ISSR and RAPD data (r = .78, p < .05). No clear clustering was found within P. graminea populations in relation to their geographical origins. Applying the unweighted pair group method with arithmetic mean (UPGMA) procedure and principal coordinates analysis (PCoA) revealed no obvious clustering of isolates based on geographic region. Totally, gene diversity of 0.2 was noticed among P. graminea isolates. High level of genetic differentiation (PhiPT = 0.257; p ≤ .001), with 74% of the genetic variation occurring within populations and 26% occurring among populations, indicated the existence of population differentiation. In addition, a moderate amount of gene flow (Nm = 1.1985) was found between populations. Information obtained from this study may be beneficial to design and improve management strategies such as breeding resistant barley varieties to leaf stripe disease.

Characterization of Annona Genotypes by ISSR and SSR Markers

Background: Annona spp. are one of the underutilized fruit crop having great commercial and medicinal value and large diversity present in Maharashtra which is untapped. The present study conducted to characterize the Annona genotypes by ISSR and SSR markers for future germplasm conservation and crop improvement programme. Methods: Ninety genotypes were collected from various regions of Maharashtra. These ninety genotypes and eleven varieties from All India Coordinated Research Project on Arid Zone Fruits, MPKV, Rahuri were screened for morphological and biochemical characters. After morphological and biochemical characterization twenty-two superior genotypes were characterized using ISSR and SSR markers. Result: Among the 29 ISSR primers used, 20 were found polymorphic which produced a total of 171 reproducible amplicons, in which 109 amplicons (75.43%) were polymorphic. In 20 SSR primers used, 14 primers were found polymorphic which produced a total of 43 reproducible amplicons, in which 36 amplicons (83.72%) were polymorphic. Twenty unique amplicons produced by ISSR primer and eight unique amplicons produced by SSR in studied genotypes is useful in genotype/variety identification in future crop improvement. The dendogram generated based on UPGMA method of cluster analysis using ISSR and SSR marker data revealed little different but similar grouping of genotypes into two major clusters viz., cluster A and cluster B. The UPGMA based cluster analysis using dice similarity coefficient grouped Annona genotypes into two major clusters which differentiate squamosa and atemoya species. The distribution of the genotypes in the dendogram was mostly consistent with the known pedigree information, geographical locations and the morphological attributes. Genotypes collected from Purandar, Sawargaon, Pemgiri and Ajanta districts of Maharashtra formed cluster as per geographic collection. The close relationship across genotypes might be explained by either historical relationship to sharing common ancestor or more likely geographical proximity and large population size which favour genetic interchange. This low genetic difference among genotypes suggests that there was more gene flow through random mating without barrier within agro-ecological zones. ISSR and SSR markers gives direction in characterization of Annona genotypes but more areas need to be survey and explore for tapping genetic diversity to widen the gene pool. The screened material found superior need to be prioritized in terms of in-situ and ex-situ conservation for further evaluation and crop improvement.

Genetic Diversity and Population Structure of Canarium tramdenum Dai and Yakovl. in Northern Vietnam

Canarium tramdenum occurs naturally in subtropical and tropical regions of Indochina and China. The wood is used for making high quality furniture and the fruit and leaves are used in traditional medicine. However, a lack of information on genetic diversity and population structure has handicapped the genetic conservation and domestication of this high-value species. This study evaluated genetic variation within and among four C. tramdenum populations. Sixty individuals were collected from four natural populations in Vietnam in the provinces of Ninhbinh, Bacgiang, Nghean, and Backan. Genetic diversity and genetic structure were determined using 20 ISSR markers. A total of 192 DNA fragments with sizes ranging from 110 bp to 3,000 bp were detected, of which 154 segments (80.2%) were polymorphic and 38 segments (19.8%) were monomorphic. The ISSR data indicated a moderate degree of genetic diversity for the species (h = 0.252). The four populations were separated into three genetic clusters with low levels of genetic distance between them. AMOVA result showed that most (78%) of the genetic variation was within the populations. The moderate to high genetic diversity of C. tramdenum and the low genetic differentiation among populations suggested that all existing natural populations in the particular regions needed to be preserved to protect the genetic diversity of this species.

Morpho-molecular characterization of Bipolaris and Exserohilum spp. infecting various agricultural crops

The study was undertaken with major objective to differentiate fungal isolates belonging to various species of Bipolaris and Exserohilum infecting various agricultural crops. After routine isolation and purification of more than 35 attempts, 13 isolates were morphologically characterized into 8 species namely, Bipolaris cynodontis (IQBC-1 and DQBC-2), B. holmii (IQBH-1), B. micropus (IQBM-1), B. oryzae (DQBO-1, DQBO-2), B. sorghicola (DQBS-1, DQBS-2), B. tetramera (DQBT-1, DQBT-2), Exserohilum longirostrata (IQEL-1) and E. rostratum (DQER-1 and DQER-2). Molecular characterization of all the isolates using RAPD, ISSR and URP markers also revealed genetic variation. Out of 24 RAPD primers, only 9 (OPA-2, OPA-4, OPA-9, OPB-4, OPB-8, OPC-1, OPC-2, OPC-5 and OPE-5) could amplify the DNA sequence showing good polymorphism. Out of 20 ISSR primers, only 6 (ISSR 1, ISSR 13, ISSR 15, ISSR 17, ISSR 19 and ISSR 20) could show good polymorphism. Out of 13 URPs, only 5 (URP 4R, URP 6R, URP 9F, URP 13R and URP 38F) could amplify with a greater number of bands. In all the three makers, similarity matrix value using Jaccard’s coefficient ranged from 0.149 to 0.548 revealing genetic co-relation among isolates. Combined clustering of RAPD, ISSR and URP data showed relatively low genetic similarity coefficient ranging from 14.92 to 54.76 among isolates which revealed stronger co-relation among isolates. Cluster analysis based on UPGMA provided a clear resolution of relationship among all the 13 isolates belong to 6 Bipolaris and 2 Exserohilum species and confirmed the morphological characterization of the same. Further, molecular markers especially, RAPD, ISSR and URP have revolutionized the genetic analysis of plant pathogens including fungi and their application can greatly help in characterizing related genera and delineation of inter and intra-species complex of fungi.

Transferability of ISSR, SCoT and SSR Markers for Chrysanthemum × Morifolium Ramat and Genetic Relationships Among Commercial Russian Cultivars.

Characterization of genetic diversity in germplasm collections requires an efficient set of molecular markers. We assessed the efficiency of 36 new SCoT markers, 10 new ISSR markers, and 5 microsatellites for the characterization of genetic diversity in chrysanthemum core collection of 95 accessions (Russian and foreign cultivars). Seven new SCoT (SCoT12, 20, 21, 23, 29, 31, 34) and six new ISSR markers ((GA)8T, (CT)8G, (CTTCA)3, (GGAGA)3, (TC)8C, (CT)8TG) were efficient for the genetic diversity analysis in Chrysanthemum × morifolium collection. After STRUCTURE analysis, most Russian cultivars showed 20–50% of genetic admixtures of the foreign cultivars. Neighbor joining analysis based on the combination of SSR, ISSR, and SCoT data showed the best accordance with phenotype and origin compared to the separate analysis by each marker type. The position of the accessions within the phylogenetic tree corresponded with the origin and with some important traits, namely, plant height, stem and peduncle thickness, inflorescence type, composite flower and floret types, flower color, and disc color. In addition, several SCoT markers were suitable to separate the groups distinctly by the phenotypical traits such as plant height (SCoT29, SCoT34), thickness of the stem and peduncle (SCoT31, SCoT34), and leaf size and the floret type (SCoT31). These results provide new findings for the selection of markers associated with important traits in Chrysanthemum for trait-oriented breeding and germplasm characterization.

Molecular characterization and phylogenetic analysis of Rhynchophorus ferrugineus (Olivier) in Eastern Province, Saudi Arabia.

Red palm weevil (RPW) is the most aggressive date palm parasite in the Middle East, and especially in the Gulf region. Originated in Southeast Asia, this pest has been detected in the entire Arabian Peninsula, North Africa, Italy, Latin America, and other territories. It is important to local from obtrusive species, which help augmenting the pest control strategies. In the present study we collected 21 RPW samples from 21 different locations in the Eastern Province, Saudi Arabia to genetically characterize them using RAPD- and ISSR-based clustering. Unweighted pair group method with arithmetic mean (UPGMA) for RAPD data categorized the 21 accessions into seven distinct groups, with Al-Oyonn and Juaymah each categorized in solitary group, meanwhile, UPGMA for ISSR indicated six different groups, with Battaliyah, Al-Oyoon, and Juaymah each assigned to a separate group. Combining RAPD and ISSR data revealed two accession; Al-Oyoon and Juaymah that might be considered obtrusive species. Based on distance calculations, we proposed that the potential origins of RPW collected from these locations are Iran and the United Arab Emirates. However, this assumption needs further studies for confirmation.
