植物中miR160／miR167／miR390家族及其靶基因研究进展
Advance on miR160/miR167/miR390 family and its target genes in plants
摘要
Abstract
MicroRNA ( miRNA) is endogenous and non-coding small RNA with 21-23 nucleotides, and it widely exits in eukaryotes. MiRNAs repress gene expression at post transcriptional level by acting on near-perfect complementary se-quences in mRNA coding region to guide cleavage and translational repression, and it plays an important role in regula-ting cell cycle and development timing of biology. Three miRNA families including miR160, miR167 and miR390 all tar-geting to ARF ( Auxin response factor) gene family have been reviewed, and which indicates that they fulfil the similar and differential function. For example, miR160/miR167/miR390 plays an important role in plant development. But miR160 focuses on regulating embryo and root development, miR167 focuses on the regulation of flowers and fruit devel-opment, and miR390 has remarkable effect on regulating plant lateral organ development. Moreover, feedback regulation exists between miR160/miR167/miR390 and their target genes.关键词
