Gene Symbol
- Os01g0909200 <=> OsDCL,DCL
Function
- The activity of Dicer or Dicer-like (DCL) proteins is required for the maturation of miRNAs and siRNAs.
- OsDCL1 control developmental arrest at the seedling stage and pleiotropic developmental defects.
miRNA/siRNA
- All miRNAs tested were greatly reduced in OsDCL1IR but not OsDCL4IR transformants,indicating that OsDCL1 plays a critical role in miRNA processing in rice. In contrast, the production of siRNA from transgenic inverted repeats and endogenous CentO regions were not affected in either OsDCL1IR or OsDCL4IR transformants, suggesting that the production of miRNAs and siRNAs is via distinct OsDCLs.
