Endogenous small RNAs function in RNA interference (RNAi) pathways to control gene expression through mRNA cleavage,translational repression,or chromatin modification.Plants and animals contain many microRNAs (miRNAs) that play vital roles in development,including helping to specify cell type and tissue identity.To date,no miRNAs have been reported in unicellular organisms.
