The results of the project will make it possible to identify new variants, virulence and pathogenicity genes of bacterial blight and scab pathogens, and help to develop targeted control methods. Prevention of the spread of infection in cultivated orchards and wild populations will be achieved by analyzing natural reservoirs of pathogens and identifying centers of infection in natural and artificially created conditions. Identification of new races and strains will make it possible to assess their level of pathogenicity and to limit their spread in a timely manner. At present, ribotypes and strains of <em>Erwnina amylovora<\/em>, as well as races of fungal pathogen of <em>Venturia<\/em> genus have been not determined in the country, the region of their distribution have been not determined, and the same methods of control are applied without complete eradication of infection, which leads to the death of entire orchards. Whole-genome studies will help to assess the rate of pathogen evolution in the country and predict the emergence of highly pathogenic strains.<\/p>\n<p><strong>The goal of the project<\/strong><strong>: <\/strong><\/p>\n<p>The goal of the project is a full genomic and molecular genetic study of different strains and isolates of <em>Erwnina amylovora<\/em>, <em>Venturia inaequalis<\/em>, <em>Venturia pirina,<\/em> and <em>Venturia asperata<\/em> circulating in wild and cultivated populations of apple and pear trees, as well as in natural reservoirs, in order to analyze the evolution and pathogenicity of fire blight and scab pathogens of fruit crops.<\/p>\n<p><strong>Expected results<\/strong>:<\/p>\n<p>1) At least 600 samples of plant material will be collected from populations of wild apple trees in the Dzhungarian and Zailiyskiy Alatau, as well as from cultivated apple and pear trees in orchards in southern Kazakhstan. Collection of plant material from mountain ash and hawthorn plants, natural reservoirs of <em>Erwnina amylovora<\/em> pathogen. Samples of flowers, branches, and leaves will be taken in spring and summer. GPS coordinates will be recorded for each tree. Samples will be collected in natural pools from plants growing in close proximity to apple and pear populations and at least 1 km away from wild and cultivated apple populations.<\/p>\n<p>2) Metagenomic analysis of aboveground plant parts and identification of the main bacterial and fungal pathogens affecting apple, pear, hawthorn and mountain ash will be conducted. Identification of new bacteria and fungi not previously studied in Kazakhstan, determination of associated microflora and mixed infection. Samples positive for <em>Erwnina amylovora<\/em> and genus <em>Venturia<\/em> will be analysed additionally by loop isothermal amplification with specific primers to the pathogen genome.\u00a0 For metagenomic analysis, amplification of the complete 16S RNA genome of bacterial and ITS regions of fungal pathogens will be carried out by nanopore sequencing to increase species resolution. Samples with mixed infection including fire blight and scab will be identified.<\/p>\n<p>3) Full genome sequencing of strains and isolates of <em>Erwnina amylovora, Venturia inaequalis, Venturia pirina,<\/em> and <em>Venturia asperata<\/em> found on apple, pear, mountain ash and hawthorn plants will be conducted. Population and phylogenetic analyses will be conducted to determine the level of heterogeneity and evolutionary vector of the pathogens. Identification of highly variable and conserved regions of genomes, level of variation in the whole genome and depending on host and region of distribution. Significant mutations in virulence genes will be identified, and new variants will be identified. Promising genome regions for highly sensitive pathogen detection will be identified. Known and new races of the genus <em>Venturia<\/em> and <em>Erwnina amylovora<\/em> ribotypes will be identified for the first time in the country.<\/p>\n<p>4) The expression of virulence genes of pathogens will be analyzed <em>in vitro<\/em> and in infected apple and pear samples, transcriptome profiles will be determined, and new virulence gene variants and their combinations will be identified. Comparative analysis of virulence gene expression in different strains and isolates will be conducted.<\/p>\n<p>5) A data map of <em>Erwnina amylovora<\/em> and <em>Venturia<\/em> fungal pathogens circulation in populations of wild and cultivated apple and pear trees in the country will be developed.<\/p>\n<p>6) Pure cultures of pathogens will be obtained and a collection of strains, ribotypes and isolates distributed in the country will be created.

Primers for identification of <em>Erwnina amylovor<\/em>a and <em>Venturia<\/em> by isothermal amplification method were designed.<\/p>\n<p>The developed primers were validated on positive controls of the laboratory collection, as well as on synthetic controls. The lower sensitivity threshold of the designed primers was 20-40 fg.<\/p>\n<p>Metagenomic analyses were performed for collected samples from orchards and wild populations. Metagenomic analysis was performed by sequencing 16sRNA and ITS1-ITS2 genes on the MinIon platform. Of the pathogenic microflora, bacteria of the genus <em>Erwinia<\/em> were predominantly identified, while endophytic microflora was represented by <em>Pseudomonas<\/em>, <em>Klebsiella<\/em> and <em>Pantoea<\/em>. The associated microflora was represented by bacteria of the genus <em>Pseudomonas<\/em>. In plants from wild populations, the bacterium <em>Pseudomonas fluorescens<\/em> was predominantly identified from the endophytic microflora. Of pathogenic fungi, the genus <em>Alternaria<\/em> was identified, mainly <em>Alternaria mali<\/em> species causing alternariosis of apple trees. In hawthorn and mountain ash, <em>Diplocarpon mespili<\/em>, <em>Alternaria<\/em> and <em>Monilinia johnsonii<\/em> were identified among pathogenic fungi. Among endophytic fungi, the following species were identified: <em>Alternaria infectoria, Alternaria sclerotigenum, Aspergillus terreus, Penicillium chrysogenum,<\/em> and<em> Fusarium lateritium.<\/em> All the above endophytic fungal species were detected in wild populations, in cultivated gardens only <em>Alternaria infectoria<\/em> was detected.<\/p>\n<p>The composition of pathogenic and endophytic microflora varied depending on the studied plant organ. In leaves were found: <em>Pseudomonas, Klebsiella, Pantoea, Alternaria sclerotigenum, Aspergillus terreus. Alternaria mali<\/em>.

The most genetically similar strains for Erwinia amylovora from the NCBI database were N434113.1 and FN666575.1. Most Erwinia amylovora isolates belong to the R1 ribotype. The highest number of variations was found in the plasmid genome and non-protein coding regions of the genome. The majority of variations, 54%, were found in isolates from wild apple trees. Seven isolates of Venturia inaequalis showed the highest genetic relationship with race 1, and one isolate with race 2. 125 variations were identified in 8 Venturia inaequalis isolates collected from geographically distant populations. Three unique variations were identified in genes encoding effector proteins in Venturia inaequalis race 1. Five isolates of Erwinia amylovora belonging to A-genotype were identified when studying CRR1 genome regions. Between 246 and 260 SNPs were identified among the 30 studied isolates. Venturia inaequalis isolates showed homology of 98.7%. The highest genetic distance was 0.015, while the lowest genetic distance was 0.009. Based on the analysis of Erwinia amylovora across &gt;3800 genome positions, the isolates form three main phylogenetic clusters, differing by an average of 147 SNPs. A collection of pure cultures of Erwinia amylovora (30 isolates) and Venturia inaequalis (8 isolates) was created.<\/p>\n<p><strong>Publications and patents<\/strong><\/p>\n<ol>\n<li>Kerimbek, N., Kapytina, A.
