摘要:
植物体中含有丰富的具有生理活性的化合物，其代谢过程错综复杂且受多元调控。MicroRNA(miRNA)是约23 nt大小的非编码RNA分子，属于参与基因调控的反式作用因子。在植物中，miRNA主要通过与靶基因的特异性结合来对其进行转录后水平的调控。近年来，关于植物miRNA的研究发展得非常迅速。越来越多的研究表明，miRNA几乎参与调控了植物各个生长阶段的生理过程。药用天然活性物质主要来源于相关植物的次生代谢。miRNA主要通过靶向作用植物细胞次生代谢途径上的酶及转录因子，或者通过影响植物激素的信号转导来调控次生代谢产物化学成分的合成。本文介绍了miRNA的生物合成、作用机制和生理功能，以及与植物化学相关的次生代谢的常见途径，主要综述了近年来国内外对miRNA在一些具有药用活性的植物天然化学产物合成过程中的调控作用的研究进展，并且展望了未来对药用植物中miRNA的研究方向。
