摘要
microRNA(miRNA)是22nt左右的非编码RNA,主要在转录后水平调节基因的活性。miRNA通过与靶基因的互补位点结合从而降解靶基因mRNA或抑制其翻译。近年的研究发现,miRNA在植物生长发育中发挥着重要的调控作用。目前已知一些miRNA参与植物激素信号途径的切入点,这为我们了解miRNA和植物激素在植物发育中的作用提供了新思路。本文综述了miRNA参与植物激素信号应答及生物合成的研究进展,并对一些miRNA在植物激素信号应答中可能的作用进行了讨论。
MicroRNAs (miRNAs) are noncoden RNAs with about 22 nucleotides, and have post transcriptional regulation activities, miRNAs can degrade and/or repress the translation of target genes by binding to the complementary sites of target genes. Over the past years, miRNAs have been validated to play crucial roles in plant growth and development. Recent researches have witnessed the identification of intersection between miRNAs pathways and phytohormone responses, which improves our understanding of miRNAs and hormone action in developmental control. In this review, we highlight the progress on the current known relationship of miRNAs with phytohormone signaling, and the potential roles of some specific miRNAs in hormone signaling were also discussed.
