<p style="text-align: justify;"><strong>Aim</strong>: The Caucasus is considered as a possible primary centre of origin of grapevine. The aim of our research work was to study genetic diversity among cultivated Caucasian grape varieties and wild relatives originating from Near-Caspian areas of Azerbaijan on the basis of simple sequence repeat (SSR) markers.</p><p style="text-align: justify;"><strong>Methods and Results</strong>: Microsatellite allele data obtained in 31 local table grape varieties of <em>Vitis vinifera</em> L. ssp. <em>sativa</em> (Absheron region) and 34 wild varieties of <em>Vitis vinifera</em> L. ssp. <em>sylvestris</em> (Nabran, Davachi and Guba regions) were used to estimate population genetic parameters such as the polymorphism information content (PIC), the probability of identity (PI) and the frequency of null alleles (r). The genetic differences among the wild populations and between the wild and the cultivated gene pools were assessed using POPGENE, Arlequin and GENETIX programs. The selected fifteen microsatellite (SSR) markers revealed a high degree of polymorphism within and among the grape populations analyzed. The genetic similarity index ranged from 0.02 to 0.933.</p><p style="text-align: justify;"><strong>Conclusions</strong>: Among the selected markers, VVMD28 and VVMD36 displayed the highest diversity level regarding the expected heterozygosity and PIC (highest values) and PI (lowest values). In consequence, we postulate that these two markers are the most appropriate ones for the identification of grape accession and the determination of genetic diversity among cultivated and wild grape genotypes. Clustering analysis based on SSR markers data led to a good separation between cultivated and wild accessions and between wild accessions originating from different regions.</p><p style="text-align: justify;"><strong>Significance and impact of the study</strong>: The fifteen microsatellite markers used in this study were highly informative for the identification and analysis of genetic structure of Azerbaijan grapevine populations and clarified the relationships among grape accessions.</p>

The domestication and spreading of grapevine as well as the gene flow history had been described in many studies. We used a high-quality 7k SNP dataset of 1,038 Eurasian grape varieties with unique profiles to assess the population genetic diversity, structure, and relatedness, and to infer the most likely migration events. Comparisons of putative scenarios of gene flow throughout Europe from Caucasus helped to fit the more reliable migration routes around the Mediterranean Basin. Approximate Bayesian computation (ABC) approach made possible to provide a response to several questions so far remaining unsolved. Firstly, the assessment of genetic diversity and population structure within a well-covered dataset of ancient Italian varieties suggested the different histories between the Northern and Southern Italian grapevines. Moreover, Italian genotypes were shown to be distinguishable from all the other Eurasian populations for the first time. The entire Eurasian panel confirmed the east-to-west gene flow, highlighting the Greek role as a “bridge” between the Western and Eastern Eurasia. Portuguese germplasm showed a greater proximity to French varieties than the Spanish ones, thus being the main route for gene flow from Iberian Peninsula to Central Europe. Our findings reconciled genetic and archaeological data for one of the most cultivated and fascinating crops in the world.

Изучение агробиологических свойств сортов в привязке к их генетике имеет важное значение как для прикладных, так и для фундаментальных исследований. Одним из наиболее ярко выраженных признаков у виноградного растения является наличие или отсутствие антоциановой окраски ягод, которая, в свою очередь, контролируется кластером генов MYB, расположенных во второй хромосоме кариотипа. Особенный интерес для научного сообщества представляют клоны сортов, являющихся референсными при сравнении для изучения генетического разнообразия рода Vitaceae . Таким образом, в статье представлены результаты изучения строения аллелей гена VvMybA1 у 32 клонов известных распространенных сортов винограда: Мерло, Каберне-Совиньон, Рислинг, Алиготе, Пино белый и Совиньон блан. В результате, у всех клонов были выявлены аллели гена VvMybA1, характерные для окрашенных и неокрашенных сортов. Это же подтверждается результатом сравнения секвенированных последовательностей с базой данных NCBI, при помощи сервиса NCBI BLAST. Для всех клонов неокрашенных сортов было установлено наличие аллели с ретротранспозонной вставкой, блокирующей нормальную экспрессию гена и, следовательно, детерминирующего отсутствие антоцианинов в ягодах. Также были обнаружены одно- и динуклеотидные замены, являющиеся общими для групп и некоторых отдельных клонов и в целом характерные для белоягодных и красноягодных сортов. Помимо этого, были выявлены мутационные различия, характерные для конкретных клонов, которые, в свою очередь, выражены в двоении нуклеотидных пиков при секвенировании и объясняются гетерогенностью изученных генотипов, то есть их происхождением. Таким образом, при изучении клонов шести сортов было подтверждено наличие в них характерных аллелей, выявлены уникальные для окрашенных и неокрашенных сортов изменения, а также созданы референсные последовательности генов сортов, содержащихся на ампелографическом участке Анапской зональной опытной станции, которые могут использоваться в дальнейшей работе по изучению данного признака.Research into agrobiological characteristics of grape varieties in connection with their genetics is important both for applied and fundametal studies.The presence or absence of anthocyanin color of the berries is one of the best expressed traits of grape plant. This trait is controled by the cluster of MYB genes located in the second chromosome of the caryotype. Some grape varieties serve as references in comparative studies aimed to investigate the Vitaceae genetic diversity, and clones of such varieties are of special interest. The paper reports findings regarding the structure of alleles of VvMybA1 gene in 32 clones of popular grape varieties: ‘Merlot’, ‘Aligoté’, ‘Cabernet Sauvignon’, ‘Pinot blanc’, ‘Riesling’ and ‘Sauvignon blanc’. Alleles of VvMybA1 gene that are typical of varieties with colored or noncolored berries were detected in all study clones, and this was confirmed by comparing the sequenated sequences to the NCBI database with the aid of the NCBI BLAST service. It was established that all study clones of varieties with noncolored berries had an allele with a retrotransposon insertion blocking normal expression of the gene which, therefore, determines the absence of anthocyanins in the berries. One- and di-nucleotide replacements common to groups of the study clones and to some individual study clones were also detected. These replacements are, on the whole, typical of white-and red-berried grape vartieties. In addition, mutation-related differences typical of definite clones were revealed. These differences manifest themselves by double nucleotide peaks in sequencing and can be ascribed to heterogeneity of the study genotypes, i. e. their origin. Thus, the presence of typical alleles in the study clones of six grape varieties was confirmed, changes unique to varieties with colored and noncolored berries were revealed, and reference sequences of genes maintained in the collection plot of the Anapa Zonal Experiment Station were developed, for further research into the trait of interest.

Plasmopara viticola oomycete is a seasonal pathogen that causes one of the most harmful diseases of the grapevine – downy mildew. The study of the biodiversity of Plasmopara viticola in various zones of viticulture has fundamental goals, as well as practical ones, as it is important for understanding the epidemiological cycle of P. viticola and for refining disease prediction models. The purpose of the work is to study the genetic diversity of P. viticola in the vineyards of the Krasnodar Territory, including on the grape varieties with different levels of resistance to downy mildew. The study was conducted on pathogens samples collected on grape plants of varieties with varying degrees of resistance to downy mildew. The collection of material was carried out in May-August 2019 in various zones of the Krasnodar Territory. 48 samples of P. viticola were analyzed. The DNA markers BER, ISA, CES, GOB, PV91, PV137, PV143, PV144 recommended for studying the genetic diversity of P. viticola were used. The work was performed by PCR. The amplification products were evaluated by the method of fragment analysis. DNA-marker GOB identified 37 alleles of different sizes, PV144 – 20, CES – 10, BER – 3, PV91 – 3, PV137 – 2, ISA – 1, PV143 – 1. It was shown that P. viticola populations are variable on different varieties and in different geographical areas. This study was conducted in the Krasnodar Territory for the first time.

The expansion of viticulture in the world is accompanied by the spread of diseases and plant pests. Phylloxera is one of those organisms causing enormous damage to the world’s viticulture. The discovery of the possibility of grafting varieties on stock has led to the development of the breeding of stock originating from North America. Currently, the active use of different types of molecular markers for the identification and study of the genetic diversity of grapes allows to more accurately and efficiently study the biological peculiarities and genetics of plants. Obtaining good reproducibility of the analysis results and revealing the polymorphism between varieties and clones when using different types of markers, you can further use this knowledge for breeding in the selection of crossed pairs. The aim of the study in the present article was to study the common stock grape varieties - hybrids of American species. The article presents a study of the five most famous stock grape varieties: Kober 5BB and 420-A, Paulsen 1103, 101-14 and Richter 57 to identify genetic relationships and polymorphism between samples, based on the use of IRAP and iPBS primers. We used thirteen selected DNA markers that generated a total of 308 polymorphic DNA bands with 54.95 % polymorphism. The effectiveness of iPBS markers was comparable or even more effective than the markers based on retrotransposons. As a result of research, differences and commonality between stocks were clearly demonstrated by both cluster analysis and PCoA analysis.
