| یکی از فرآیندهای کنترلی در بسیاری از گیاهان از جمله چغندرقند انتقال از مرحله رشد رویشی به زایشی میباشد که توسط شبکه پیچیدهای از پروتئینها تنظیم میشود. تاکنون چندین مسیر تنظیمی دخیل در مسیر گلدهی و بولتینگ و ژنهای موثر در آنها در گیاه مدل آرابیدوپسیس شناسایی شده است. یک مسیر موثر در انتقال از مرحله رویشی به زایشی مسیر وابسته به سن است که تحتتاثیر دو miRNA172 و miRNA156 میباشد. ژنهای کدکننده miRNA ها در بین گیاهان بسیار گسترده و حفاظتشده هستند. در این تحقیق، برای شناسایی توالی این دو ژن در ژنوم چغندرقند، توالی آنها از چندین گیاه جمعآوری و با توالیهای Refseq-genomic چغندرقند مورد همردیفی قرار گرفتند. نواحی با توالی مشترک شناسایی و اطلاعات آنها به طور دقیق مورد بررسی قرارگرفت. نتایج نشان داد که در ژنوم چغندرقند برای ژن کدکننده miR156 فقط 127 جفت باز از کروموزوم شماره 2 و ژن کدکننده miR172 فقط 110 جفت باز از کروموزوم شماره 9 دارای توالیهای کامل پیشساز miRNA بودند. جداسازی ژن کدکننده miR156 از ژنوم گیاه چغندرقند، با طراحی آغازگرهای اختصاصی از نواحی ابتدا و انتهای ژن انجام گرفت. ژن کدکننده miR156 توسط تکنیک واکنش زنجیرهای پلیمراز و با استفاده از آغازگرهای اختصاصی MIRF و MIRR از روی DNA ژنومی چغندرقند تکثیر شد. همانگونه که انتظار میرفت قطعه DNA 127 جفت باز تکثیر شد و در نهایت از طریق توالییابی مشابهت 99 درصدی توالی تکثیر شده با توالی شناسایی شده ژن کدکننده miR156 به دست آمد و صحت توالی شناسایی شده به عنوان ژن کدکننده miR156 در چغندرقند تأیید گشت. شناسایی و مطالعه این ژنهای مؤثر در فرآیند گلدهی راه را برای قابلیت بررسی عملکرد دقیق آنها در فرآیندهای گلدهی و بولتینگ چغندرقند خواهد گشود. | ||

| چکیده [English] | ||
| Transition from vegetative to reproductive stage is one of the important procedures in most crops such as sugar beet which is regulated by the complex network of proteins. So far, several regulatory pathways involved in flowering and bolting and related genes have been identified in the Arabidopsis as a model plant. Age-related pathway is one of the important pathways involved in transition from vegetative to reproductive stage that is influenced by miR156 and miR172. In order to identify the sequence of the above mentioned genes in sugar beet genome, their sequences were collected from several plants and were aligned with sugar beet Refseq-genomic sequence. Regions with a common sequence were identified and evaluated in detail. For miR156 coding gene, only 127 bp in chromosome 2, and for miR172 coding gene only 110 bp in chromosome 9 had the full-length of miR precursor sequence in the sugar beet genome. In order to isolate the miR156 coding gene from the sugar beet genome, specific primers were designed. The miR156 coding gene was amplified from genomic DNA of sugar beet by polymerase chain reaction technique using specific primers of MIRF and MIRR. As expected, the 127 bp gene was amplified and showed 99% similarity with the sequence of the miR156. Identifying and studying these effective genes in the flowering process will open the way for the ability to verify their exact performance in sugar beet flowering and bolting processes. | ||
