Research Progress of Plant MicroRNAs in Stress Response
microRNAs(miRNAs)are a class of endogenous,noncoding,small RNAs that have essential regulato-ry functions in plant growth,development,and stress response processes.This study reviewed the research progress of plant miRNAs in response to biotic and abiotic stresses(salt stress,drought stress,temperature stress,nu-trient stress,and pathogen biological stress).The problems in plant miRNAs research were pointed out and the fu-ture development was prospected,providing ideas and references for further studies on miRNAs research and ap-plication in plant resistance to stress response.
