摘　　要：Molecular breeding is one of the most effective methods for improving the performance of crops.Understanding the genome features of crops,especially the physiological functions of individual genes,is of great importance to molecular breeding.Evidence has shown that genomes of both animals and plants transcribe numerous noncoding RNAs,which are involved in almost every aspect of development.In crops,an increasing number of studies have proven that non-coding RNAs are new genetic resources for regulating crop traits.In this review,we summarize the current knowledge of non-coding RNAs,which are potential crop trait regulators,and focus on the functions of long non-coding RNAs(lncRNAs)in determining crop grain yield,phased small-interfering RNAs(phasiRNAs)in regulating fertility,small interfering RNAs(siRNAs)and microRNAs(miRNAs)in facilitating plant immune response and disease resistance,and miRNAs mediating nutrient and metal stress.Finally,we also discuss the next-generation method for ncRNA application in crop domestication and breeding.
