چکیده مقاله :
پیشرفت هایی که در دنیا اتفاق می افتد، سبب ایجاد تغییراتی در شرایط زندگی موجودات زنده از جمله گیاهان می گردند. گیاهان باید بتوانند با روش های مختلف حتی روش های مولکولی با شرایط تنش زای محیطی سازگارشوند. یکی از ساز و کارها، تنظیم بیان ژن ها بعد از رونویسی توسط miRNAs (میکروRNAها) است. میکروRNA ها، اغلب 20 تا 22 نوکلئوتید دارند که برخی از ژن های هدف آنها متعلق به عوامل رونویسی می باشند. بیان میکروRNA ها در پاسخ به تنش کم آبی تغییر می کند. در پژوهش حاضر، پیازهای نرگس هلندی در شرایط متفاوت آبیاری (از یک بار در هفته تا دو ماه یک بار) کشت شدند. از برگ‌های گیاهان 60 روزه برای استخراج ژن هدف میکروRNA 159 ، MYB و ژن هدف میکروRNA 172، AP2 ، با روش qPCR استفاده شد. نتایج نشان دهنده افزایش بیان معنی دار ژنهای MYB و AP2 و عدم بیان میکروRNA های 159 و 172در نمونه های تیمار و کنترل بود. لذا، miR172-miR159 تحت تاثیر تنش کم آبی قرار نمی گیرد. با توجه به اینکه بیان ژنهای کم آبی برای اولین بار در گیاه نرگس هلندی ارزیابی شده است، به همین دلیل این پژوهش می تواند زمینه خوبی برای بررسی بیشتر در این مورد را فراهم کند.
چکیده انگلیسی:
Advances in the world are causing changes in the living conditions of living things, including plants. Plants must be able to adapt to environmental stressful conditions in a variety of ways, even molecular methods. One mechanism is to regulate gene expression after transcription by miRNAs (microRNAs). MicroRNAs often have 20 to 22 nucleotides, some of whose target genes belong to transcription factors. The expression of microRNAs changes in response to dehydration stress. In the present study, Narcissus bulbs were grown under different irrigation conditions (from once a week to once every two months). The leaves of 60-day-old plants were used to extract the target gene of microRNA 159, MYB and the target gene of microRNA 172, AP2, by qPCR method. The results showed a significant increase in the expression of MYB and AP2 genes and no expression of 159 and 172 microRNAs in the treated and control samples. Therefore, miR172-miR159 is not affected by dehydration stress. Given that the expression of dehydration genes has been evaluated for the first time in the Narcissus pseudonarcissus, therefore, this study can provide a good basis for further investigation in this case.
