MicroRNAs (miRNAs) are essential regulators,involved in almost all aspects of plant growth and development.In plants,miRNAs present in all angiosperms are regarded as conserved miRNAs;in contrast,miRNAs restricted to certain lineages (lessconserved) or a single species (species-specific) constitute the non-conserved miRNAs (Cuperus et al.,2011).Different members of a miRNA family usually target similar target genes from a gene family among different species.For instance,in most analyzed plants,the well-known miR156 family,usually consisting of a number of members in a given species,collectively target SQUAMOSA-PROMOTER BINDING PROTEIN-LIKE (SPL) genes.Generally,conserved miRNAs target genes encoding transcript factors which function in diverse biological processes.This functional diversity of miRNAs is mainly achieved by the plasticity of their target genes from the same family,such as miR156-targeted SPLs and miR167-targeted ARF (AUXIN RESPONSIVE FACTOR) genes,on regulating distinct downstream genes.
