miRNA与植物体细胞胚发生

MicroRNAs (miRNAs) are a class of endogenous non-coding single strand small RNAs of 21-24 nucleotides (nt) in length, which guide post-transcriptional gene expression via mRNA cleavage or protein translation repression. miRNAs have beeen shown to play an important role in plant development, especially in zygotic embryogenesis. However, little is known about regulatory mechanism of miRNAs in somatic embryogenesis (SE) in the present study. Since the process of SE is similar with zygotic embryogenesis, the possible role of miRNA on SE is discussed in this review, which is got from the insight of roles of miRNA on zygotic embryogenesis and high-throughput sequencing data of miRNA related SE. Particularly, plant hormones transduction and transcription factors, which related to SE, are as two key points to elucidate this possible influence of miRNA on SE. The future work of miRNA on SE is discussed and prospected.
