Annotated Information
Gene Symbol
- Os04g0475900 <=> RFcw, RFCW, Rfcw, Rf17
Function
- The researchers identified a nuclear candidate gene, RETROGRADE-REGULATED MALE STERILITY (RMS) for Rf17, a fertility restorer gene for Chinese wild rice (CW)-type CMS in rice (Oryza sativa L.).
- RMS encodes a mitochondrial protein, 178 aa in length, of unknown function, unlike the majority of other Rf genes cloned thus far, which encode pentatricopeptide repeat proteins.
Mutation
- RNA interference-mediated gene silencing of RMS restored fertility to a CMS plant, whereas its overexpression in the fertility restorer line induced pollen abortion.
Expression
- The mRNA expression level of RMS in mature anthers depended on cytoplasmic genotype, suggesting that RMS is a candidate gene to be regulated via retrograde signaling.
