چکیده مقاله :
سابقه و هدف: باکتری‌های اندوفیت بدون ایجاد علایم مشخص قادر به زندگی در بخش‌های داخلی گیاه میزبان هستند و در بسیاری از موارد به عنوان باکتری‌های محرک رشد گزارش شده‌اند. این مطالعه با هدف بررسی توانایی تولید هورمون‌های محرک رشد در باکتری‌های اندوفیت سویا انجام شد. مواد و روش ها: به منظور جداسازی باکتری اندوفیت از بخش‌های مختلف سویا رقم TMS ، نمونه‌برداری از مزرعه کشاورزی دانشگاه آزاد اسلامی واحد سنندج انجام شد. پس از استخراج DNA ژنومی، به منظور تکثیر ژن 16S rDNA از روش PCR استفاده گردید. برای شناسایی باکتری جداسازی شده، محصول PCR تعیین توالی و ترادف بازی آن BLAST گردید. سویه‌ها از نظر تولید هورمون اندول اسید استیک و جیبرلین به صورت آماری در سه تکرار و در قالب طرح کاملاً تصادفی مورد بررسی قرار گرفتند. یافته‌ها: باکتری‌های جداسازی شده قادر به تولید هورمون اندول اسید استیک در حضور تریپتوفان در مقادیر 7.2 تا 15.14 میکروگرم در میلی‌لیتر و در غیاب تریپتوفان در محدوده 3.2 تا 12.14 میکروگرم در میلی‌لیتر بودند. باکتری‌ها توانایی تولید هورمون جیبرلین در مقادیر 0.11 تا 0.20 میکروگرم در میلی‌لیتر را داشتند. نتایج تعیین توالی نشان داد که باکتری جداسازی شده متعلق به سودوموناس پوتیدا است که با سویه تیپ شباهت 99 درصدی دارد. نتیجه‌گیری: این مطالعه اولین گزارش جداسازی باکتری اندوفیت سودوموناس پوتیدا از سویارقم TMS است. باکتری‌های اندوفیت جدا شده می‌توانند در افزایش رشد گیاه به کار روند.
Background & Objectives: Endophytic bacteria live inside tissues of their plant host without causing visible symptoms, and in more cases are reported as plant growth promoting bacteria. This study was conducted to determine plant growth promoting affects of endophytic bacteria associated with Soybean (cultivar TMS). Materials & Methods: In order to isolate endophytic bacteria from various parts of soybean (cultivar TMS), samples were collected from the farm of Islamic Azad University of Sanandaj. After genomic DNA extraction, 16S rDNA gene was amplified using PCR. Then, the PCR product was sequenced by BLAST. Strains were surveyed for IAA, and GA production ability was carried out using a randomized complete design in three replications. Results: The isolated bacteria were able to produce IAA in various amount 3.2 -12.14 µg/ml without tryptophan and in the presence of it, 7.2 -15.14 µg/ml. GA producing abilities were also 0.11-0.20 µg/ml for these isolates. Based on the 16S rDNA sequence, the isolated bacteria was belonged to Pseudomonas putida with 99% similarity. Conclusion: This study is the first report of isolation of P. putida from Soybean (TMS cultivar). The endophytic bacteria isolated in this study can be used to promote plant growth.
