چکیده مقاله :
سابقه و هدف: پوسیدگی نرم از مهمترین بیماری های باکتریایی سیب زمینی در ایران و جهان است. هدف از این مطالعه بررسی تنوع فنوتیپی و ژنوتیپی جدایه های موثر در ایجاد بیماری پوسیدگی نرم در مناطق مهم سیب زمینی کاری ایران بود.مواد و روش ها: غدد مشکوک به پوسیدگی نرم، در طی عملیات برداشت جمع آوری و مطالعه فنوتیپی جدایه ها بر اساس روش های متداول انجام شد. گوناگونی ژنتیکی نیز توسط روش انگشت نگاری ژنتیکی صورت گرفت. آنالیز کلاستر و بررسی ساختار جمعیت جدایه ها با نرم افزارهای SplitsTree 4.11.3 ،STRUCTURE 2.3.4 وArlequin 3.11 انجام شد.یافته ها: مطالعه انجام شده بیانگر تنوع قابل توجه در میان جدایه ها بود. به طوری که برخی از آنها ویژگی های فنوتیپی متفاوتی نسبت به جدایه های معرفی شده در مطالعات قبلی داشتند. جدایه ها در دو گروه فنوتیپی مرتبط با پکتوباکتریوم واسابیئی و پکتوباکتریوم کاروتووروم زیرگونه کاروتووروم قرار گرفتند. انگشت نگاری ژنومی نشان داد که جدایه ها از نظر ژنتیکی ناهمگن هستند و به سه جمعیت ژنتیکی قابل تقسیم بندی می باشند. پنجاه درصد جدایه های گروه فنوتیپی 1 و 77/3 درصد جدایه های گروه فنوتیپی 2 به ترتیب به جمعیت ژنتیکی 1 و 3 تعلق داشتند. همبستگی بین پروفایل انگشت نگاری ژنومی، مناطق جغرافیایی و ارقام سیب زمینی مشاهده نشد. اما فاصله ژنتیکی و کمینه و بیشینه جریان ژنی با فاصله جغرافیایی همبستگی نشان داد.نتیجه گیری: یافته های این مطالعه نشان داد که تجارت غدد بذری یکی از دلایل توسعه بیماری پوسیدگی نرم سیب زمینی به مناطق جغرافیایی هم جوار محسوب می شود.
Background & Objectives: Soft rot is one of the most important bacterial diseases of potato in Iran and the world. The aim of this study was to investigate the phenotypic and genotypic diversity of these agents in the main potato- growing regions in Iran. Materials & Methods: Samples were collected from tubers that were suspected of soft rot disease during harvest. Phenotypic characteristics were assessed by conventional methods. Genetic diversity was determined using genomic fingerprinting techniques. Cluster analysis and population structure analysis were performed by the SplitsTree 4.11.3, Arlequin 3.11 and the STRUCTURE 2.3.4 software. Results: The study showed a high level of diversity among isolates so that some of them showed phenotypic characteristics that differed from the isolates described in previous studies. Studied isolates were placed into two major groups of Pectobacterium wasabiae and Pectobacterium carotovorum subsp. carotovorum. Genomic fingerprinting profiles revealed that the isolates are genetically heterogeneous and classified into three genetic populations. 50.0% of the phenotypic group 1 isolate and 77.3% of the phenotypic group 2 isolates belonged to genetic population 1 and 3, respectively. No correlation was observed between genomic fingerprints, geographic areas, and potato cultivars, but the genetic distances and the maximum and minimum gene flow were correlated with geographic distance. Conclusion: According to the results of this study, seed trade may introduce soft rot disease to new territories in the neighboring provinces.
