MicroRNAs (miRNAs) and small interfering RNAs (siRNAs) are two classes of small regulatory RNAs derived from different types of precursors processed by distinct Dicer or Dicer-like (DCL) proteins.During evolution,four Arabidopsis DCLs and six rice (Oryza sativa) DCLs (OsDCLs) appear to have acquired specialized functions.The Arabidopsis DCLs are well characterized,but those in rice reamain largely unclear.Here we show that both knock-down and loss-of-function of rice OsDCL4,the rice homolog of Arabidopsis DCL4,led to vegetative growth abnormalities and severe developmental defects in spikelet identity.
