Abstract

Plant cells accumulate small RNA molecules that regulate plant development, genome stability, and environmental responses. These small RNAs fall into three major classes based on their function and mechanisms of biogenesis-microRNAs, heterochromatic small interfering RNAs, and secondary small interfering RNAs-plus several other less well-characterized categories. Biogenesis of each small RNA class requires a pathway of factors, some specific to each pathway and others involved in multiple pathways. Diverse sequenced plant genomes, along with rapid developments in sequencing, imaging, and genetic transformation techniques, have enabled significant progress in understanding the biogenesis, functions, and evolution of plant small RNAs, including those that had been poorly characterized because they were absent or had low representation in Arabidopsis (Arabidopsis thaliana). Here, we review recent findings about plant small RNAs and discuss our current understanding of their biogenesis mechanisms, targets, modes of action, mobility, and functions in Arabidopsis and other plant species, including economically important crops.

植物小rna:它们的生物发生、调控作用和功能。
植物细胞积累小RNA分子,调节植物发育、基因组稳定和环境反应。这些小rna根据其功能和生物发生机制可分为三大类:microrna、异色小干扰rna和继发性小干扰rna,以及其他一些不太明确的类别。每一类小RNA的生物发生都需要一个因子通路,有些特定于每个通路,有些则涉及多个通路。多样的植物基因组测序,以及测序、成像和遗传转化技术的快速发展,使人们在了解植物小rna的生物发生、功能和进化方面取得了重大进展,包括那些由于在拟南芥中缺失或代表性低而特征不明显的小rna。在这里,我们回顾了植物小rna的最新发现,并讨论了我们目前对它们在拟南芥和其他植物物种(包括重要的经济作物)中的生物发生机制、靶点、作用模式、迁移和功能的理解。
