Coevolution Pattern and Functional Conservation or Divergence of miR167s and their targets across Diverse Plant Species.

ABSTRACT: microRNAs (miRNAs), a class of endogenously produced small non-coding RNAs of 20-21 nt length, processed from precursor miRNAs, regulate many developmental processes by negatively regulating the target genes in both animals and plants. The coevolutionary pattern of a miRNA family and their targets underscores its functional conservation or diversification. The miR167 regulates various aspects of plant development in Arabidopsis by targeting ARF6 and ARF8. The evolutionary conservation or divergence of miR167s and their target genes are poorly understood till now. Here we show the evolutionary relationship among 153 MIR167 genes obtained from 33 diverse plant species. We found that out of the 153 of miR167 sequences retrieved from the "miRBase", 27 have been annotated to be processed from t
