Gene Symbol

• Os02g0255100 <=> DCW11

Function

• DCW11 is one of the down-regulated genes in CW-CMS encoding a protein phosphatase 2C (PP2C).
• DCW11 could play a role as a mitochondrial signal transduction mediator in pollen germination.

Expression

• DCW11 mRNA was preferentially expressed in anthers, with the highest expression in mature pollen.
• Knockdown of DCW11 in wild-type rice by RNA interference caused a major loss of seed-set fertility, without visible defect in pollen development.
• Since this knockdown phenotype resembled that of CW-CMS, the researchers concluded that the down-regulation of DCW11 is correlated with CW-CMS.
