MicroRNAs (miRNAs) and small interfering RNAs (siRNAs) are two types of noncoding RNAs involved in developmental regulation,genome maintenance,and defense in eukaryotes.The activity of Dicer or Dicer-like (DCL) proteins is required for the maturation of miRNAs and siRNAs.In this study,we cloned and sequenced 66 candidate rice (Oryza sativa) miRNAs out of 1,650 small RNA sequences (19 to approximately 25 nt),and they could be further grouped into 21 families,12 of which are newly identified and three of which,OsmiR528,OsmiR529,and OsmiR530,have been confirmed by northern blot.
