کلن کردن ژنRGL2 از DNA ژنومی آرابیدوپسیس (Arabidopsis thaliana)
یکی از ژنهایی که در سنتز جیبرلین در گیاه شناخته شده و موقعیت آنها در ژنوم آرابیدپسیس مشخص شده است، RGL2 می‌باشد که در این بررسی کلن گردید. با استخراج DNA از آرابیدوپسیس، اکوتیپ کلمبیا و استفاده از آغازگرهای اختصاصی که بر اساس توالی ژن مورد نظر ساخته شده بودند، این ژن تکثیر شد. پلاسمید PET-32a (+)و ژن تکثیر شده با استفاده از دو آنزیم برشی خاص به نامهای Nco I و Sal I برش داده شدند. پس از اتصال ژ...
متن کاملRole of DNA methylation in hybrid vigor in Arabidopsis thaliana.
Hybrid vigor or heterosis refers to the superior performance of F1 hybrid plants over their parents. Heterosis is particularly important in the production systems of major crops. Recent studies have suggested that epigenetic regulation such as DNA methylation is involved in heterosis, but the molecular mechanism of heterosis is still unclear. To address the epigenetic contribution to heterosis ...
متن کاملDNA Methylation Dynamics during Sexual Reproduction in Arabidopsis thaliana
DNA methylation maintains genome stability and regulates gene expression [1]. In mammals, DNA methylation is reprogrammed in the germline from one generation to the next [2]. In plants, it was considered that patterns of DNA methylation are stably maintained through sexual reproduction [3-6]. However, a recent report showed discrete variations of DNA methylation profiles from mother to daughter...
متن کاملThe DNA dioxygenase ALKBH2 protects Arabidopsis thaliana against methylation damage
The Escherichia coli AlkB protein (EcAlkB) is a DNA repair enzyme which reverses methylation damage such as 1-methyladenine (1-meA) and 3-methylcytosine (3-meC). The mammalian AlkB homologues ALKBH2 and ALKBH3 display EcAlkB-like repair activity in vitro, but their substrate specificities are different, and ALKBH2 is the main DNA repair enzyme for 1-meA in vivo. The genome of the model plant Ar...
متن کاملGenome-Wide Association of Histone H3 Lysine Nine Methylation with CHG DNA Methylation in Arabidopsis thaliana
Methylation of histone H3 lysine 9 (H3K9) is a hallmark of transcriptional silencing in many organisms. In Arabidopsis thaliana, dimethylation of H3K9 (H3K9m2) is important in the silencing of transposons and in the control of DNA methylation. We constructed a high-resolution genome-wide map of H3K9m2 methylation by using chromatin immunoprecipitation coupled with whole genome Roche Nimblegen m...
