摘要
MicroRNAs(miRNAs)是一类由19~24个核苷酸组成、在进化上高度保守的非编码小RNA,能够在转录后水平实现基因的调控。miRNAs通过调控内源性基因的表达参与大豆的生长发育、营养合成、生物胁迫以及非生物胁迫等过程。另外,miRNAs的生物合成和作用机制在植物和动物之间具有高度相似性,而大豆miRNAs的高稳定性及生物可利用性促使了其在两个物种间交叉作用的发生,即大豆miRNAs的跨物种调控。文章阐述了大豆miRNAs内源性调节及跨物种调控作用及其潜在应用价值,将为利用大豆miRNAs提高大豆品质、产量和改善人类营养健康提供理论依据。
MicroRNAs(miRNAs) are a group of non-coding small RNAs consisting of 19-24 nucleotides, which are highly conserved in evolution and can regulate genes at the post-transcriptional level. MicroRNAs(miRNAs) are involved in growth and development, nutrient synthesis, biotic stress and abiotic stress via regulating endogenous gene expression in soybean. Due to the high similarity of the biosynthesis and mechanism of miRNAs between plants and animals, the high stability and bioavailability of soybean miRNAs allow its being applied cross-species interactions between two species, which was considered as cross-kingdom regulations. In this review, we discussed the endogenous regulations and cross-kingdom regulations of soybean miRNAs and its potential applications, which provide the theoretical basis for its applications in improving the quality, nutritional values and yield of soybean as well as the human healthy.
