Small regulatory RNAs (sRNAs) are being used by plants to direct gene expression. In plants, different classes of sRNAs exist based on their biogenesis and origin. Among them, small interfering RNAs (siRNAs) and microRNAs (miRNAs) chiefly mask post-transcriptional gene expression. Initiation of translational inhibition or degradation requires the binding of miRNAs with the complementary messenger RNA (mRNA) target sites. From seed germination to plant formation, current studies report that sRNAs have a significant role in various plant developmental phases. Moreover, these sRNAs have been engaged throughout the plant evolutionary pathway, playing an active role in the shaping and functioning of various plant organs. Given the importance of sRNAs in the plant development and life cycle, this review article elaborates on the critical involvement of sRNAs in different phases of plant life starting from the seed and progressing towards the mature plant.



小的、具有调控功能的RNA(sRNA)在植物中被用来直接调控基因的表达。在植物中,基于这些sRNA的生物发生和起源可以分为不同的类别。其中,小的干扰RNA(siRNA)和microRNA(miRNA)主要发挥转录后基因表达调控的作用。转录抑制或降解的起始需要将miRNA结合到互补配对的信使RNA(mRNA)的靶位点上。从种子萌发到植株的形成,现有的研究揭示了sRNA在植物多个生长阶段均发挥重要的作用。此外,这些sRNA参与了植物的演化,在植物多个器官的塑造和功能方面发挥活跃作用。考虑到sRNA在植物发育和生活史方面的重要性,本文主要综述了植物从种子到成熟植株这个过程中不同生长发育阶段sRNA所发挥的作用。
