Plant Small RNAs: Biogenesis, Mode of Action and Their Roles in Abiotic Stresses
Small RNAs (sRNAs) are 18-30 nt non-coding regulatory elements found in diverse organisms, which were initially identified as small double-stranded RNAs in Caenorhabditis elegans. With the development of new and improved technologies, sRNAs have also been identified and characterized in plant systems. Among them, micro RNAs (miRNAs) and small interfering RNAs (siRNAs) are found to be very impor...
متن کاملSmall RNAs: classification, biogenesis, and function.
Eukaryotes produce various types of small RNAs of 19-28 nt in length. With rapidly increasing numbers of small RNAs listed in recent years, we have come to realize how widespread their functions are and how diverse the biogenesis pathways have evolved. At the same time, we are beginning to grasp the common features and rules governing the key steps in small RNA pathways. In this review, I will ...
متن کاملPlant mitochondria use two pathways for the biogenesis of tRNAHis
All tRNA(His) possess an essential extra G(-1) guanosine residue at their 5' end. In eukaryotes after standard processing by RNase P, G(-1) is added by a tRNA(His) guanylyl transferase. In prokaryotes, G(-1) is genome-encoded and retained during maturation. In plant mitochondria, although trnH genes possess a G(-1) we find here that both maturation pathways can be used. Indeed, tRNA(His) with o...
متن کاملActivity range of Arabidopsis small RNAs derived from different biogenesis pathways.
Several classes of small RNAs are known in plants and accumulating evidence indicates that different classes of small RNAs may function either cell autonomously or noncell autonomously to regulate gene expression. Here, a simple visual assay used to compare the biological activity of small RNAs produced via different biogenesis pathways suggests that transacting small interfering RNAs (tasiRNAs...
متن کاملDynamic evolution and biogenesis of small RNAs during sex reversal
Understanding origin, evolution and functions of small RNA (sRNA) genes has been a great challenge in the past decade. Molecular mechanisms underlying sexual reversal in vertebrates, particularly sRNAs involved in this process, are largely unknown. By deep-sequencing of small RNA transcriptomes in combination with genomic analysis, we identified a large amount of piRNAs and miRNAs including ove...
