Global analysis of uncapped mRNA changes under drought stress and microRNA-dependent endonucleolytic cleavages in foxtail millet

摘要

BackgroundmRNA degradation plays an important role in the determination of mRNA abundance and can quickly regulate gene expression. The production of uncapped mRNAs, an important mechanism of mRNA degradation, can be initiated by decapping enzymes, endonucleases or small RNAs such as microRNAs (miRNAs). Little is known, however, about the role of uncapped mRNAs in plants under environmental stress.
