林木胁迫相关miRNA研究进展

MiRNA is a type of 21-24 nt small non-coding RNA with wide distribution in plant species and key regulatory roles in plant growth, development and stress responses. In recent years, some progresses have been made in the identification and functional analysis of miRNA in forest trees under biotic and abiotic stresses. A set of stress-related miRNAs have been identified and the results shows there are conservation and specificity among different miRNAs in stress responses. This paper reviews the progress of stress-related miRNA in trees. The prospect in identifying trees miRNAs and functional elucidation in stress defense is analyzed in order to provide insights to the molecular mechanism and molecular breeding in stress resistance.
