Microarray-based analysis of stress-regulated microRNAs in Arabidopsis thaliana.
High-salinity, drought, and low temperature are three common environmental stress factors that seriously influence plant growth and development worldwide. Recently, microRNAs (miRNAs) have emerged as a class of gene expression regulators that have also been linked to stress responses. However, the relationship between miRNA expression and stress responses is just beginning to be explored. Here,...
متن کاملIdentification of Nitrogen Starvation-Responsive MicroRNAs in Arabidopsis thaliana
microRNAs (miRNAs) are a class of negative regulators that take part in many processes such as growth and development, stress responses, and metabolism in plants. Recently, miRNAs were shown to function in plant nutrient metabolism. Moreover, several miRNAs were identified in the response to nitrogen (N) deficiency. To investigate the functions of other miRNAs in N deficiency, deep sequencing t...
متن کاملNatural Variation in Biogenesis Efficiency of Individual Arabidopsis thaliana MicroRNAs
Like protein-coding genes, loci that produce microRNAs (miRNAs) are generally considered to be under purifying selection, consistent with miRNA polymorphisms being able to cause disease. Nevertheless, it has been hypothesized that variation in miRNA genes may contribute to phenotypic diversity. Here we demonstrate that a naturally occurring polymorphism in the MIR164A gene affects leaf shape an...
متن کاملMicroRNA gene evolution in Arabidopsis lyrata and Arabidopsis thaliana.
MicroRNAs (miRNAs) are short regulatory RNAs processed from partially self-complementary foldbacks within longer MIRNA primary transcripts. Several MIRNA families are conserved deeply through land plants, but many are present only in closely related species or are species specific. The finding of numerous evolutionarily young MIRNA, many with low expression and few if any targets, supports a ra...
متن کاملکنترل ژنتیکی گلدهی در گیاه آرابیدوپسیس (Arabidopsis thaliana)
انتقال از رشد رویشی به فاز زایشی از تحولات مهم در زندگی گیاهان می‌باشد. این پدیده در گیاهان عالی تحت تاثیر بسیاری از عوامل ژنتیکی و فیزیولوژیکی می‌باشد. شناسایی این عوامل یکی از اهداف مهم در اصلاح بسیاری از گیاهان می‌باشد. در دهه‌های اخیر گیاه آرابیدوپسیس به عنوان یک گیاه مدل در بسیاری از مطالعات مربوط به عمل گلدهی به کار رفته است و بسیاری از مسیرهای مربوط به کنترل گلدهی در این گیاه مشخص شده اس...
