Evolution of lmiRNAs and their targets from MITEs for rice adaptationFA
文献摘要：
Twenty-four nucleotide long microRNAs (lmiRNAs) direct DNA methylation at target genes and regulate their transcription. The evolutionary origin of lmiRNAs and the range of lmiRNA-mediated regu-lation remain obscure. Here, we reannotated lmiRNAs and their targets in rice by applying strin-gent criteria. We found that the majority of lmiRNAs are derived from Miniature Inverted-repeat Trans-posable Elements (MITEs) and most sites targeted by MITE-derived lmiRNAs reside within MITEs, suggesting co-evolution of lmiRNAs and their tar-gets through MITE amplification. lmiRNAs undergo dynamically changes under stress conditions and the genes targeted by lmiRNAs show an en-richment for stress-responsive genes, suggesting that lmiRNAs are widely involved in plant responses to stresses. We constructed the evolutionary histories of lmiRNAs and their targets. Nearly half of lmiRNAs emerged before or when the AA genome was diverged, while the emergence of lmiRNA targets coincided with or followed the emergence of lmiRNAs. Furthermore, we found that the sequences of a lmiRNA target site underwent var-iations, coincident with the divergence of rice ac-cessions and the distribution of rice accessions in different geographical locations and climatic con-ditions. Our findings highlight MITEs as an important origin of lmiRNAs and suggest that the evolution of lmiRNA-target regulatory modules may contribute to rice adaptation to environmental changes.
