摘要
microRNA是一类小的内源性的非编码RNA,在生命有机体抵御不良环境中发挥着重要作用.氮是植物生长发育必不可少的元素,广泛参与到各种生理反应中.氮肥的施用虽然在一定程度上增加了植物的生物量,但过多的氮肥也带来了严重的环境问题,探索植物的氮代谢及氮高效利用的分子机理成为当务之急.研究表明,microRNA能够受到氮素水平的调控,并可产生相应的应答机制以维持植物的生长需求.因此,本文综述了植物对氮素的利用现状、microRNA对低氮胁迫的响应以及microRNA参与氮代谢的最新研究进展,重点探讨了miR156、miR319、miR167和miR408等在调控氮素相关的植物表型、激素、初级和次级代谢过程中的作用,为进一步利用microRNA开展氮高效生物育种奠定基础.
Abstract
MicroRNAs are a class of small,endogenous,noncoding RNAs that play an important role in the defense of living organisms to adverse environments.Nitrogen is an essential element for plant growth and development,and is widely involved in various physiological responses.Although the application of nitrogen fertilizer increases the biomass of plants to a certain extent,excessive nitrogen fertilizer also brings serious environmental problems,and it is urgent to explore the molecular mechanism of nitrogen metabolism and efficient nitrogen utilization of plants.There are many studies shown that microRNAs can be regulated by nitrogen levels and can generate corresponding response mechanisms to maintain plant growth needs.Therefore,this article reviews the current status of nitrogen utilization in plants,the re-sponse of microRNAs to low nitrogen stress,and the latest research progress of microRNAs involved in ni-trogen metabolism.The discussion objects of miR156,miR319,miR167,and miR408 were focused on the discussion objects,and their role in regulating nitrogen-related plant phenotype,hormone,primary and secondary metabolic processes was elaborated.This lays the foundation for further nitrogen-efficient bio-logical breeding using microRNAs.
