Annotated Information
Gene Symbol
- Os10g0497432 <=> Rf1 (Rf-1), rf-1, PPR791, PPR8-1, Rf-1, Rf1, Rf-1A, Rf5, Rf1a, RF5, Rf5(t)*(Rf(t)*), RF1A, PPR6
Function
- A rice nuclear gene, Rf-1, restores the pollen fertility disturbed by the BT-type male sterile cytoplasm, and is widely used for commercial seed production of japonica hybrid varieties.
- Rf-1 encodes a mitochondrially targeted protein containing 16 repeats of the 35-aa pentatricopeptide repeat (PPR) motif.
Mutation
- Sequence analysis revealed that the recessive allele, rf-1, lacks one nucleotide in the putative coding region, presumably resulting in encoding a truncated protein because of a frame shift. Rice Rf-1 is the first restorer gene isolated from cereal crops that has the property of reducing the expression of the cytoplasmic male sterility (CMS)-associated mitochondrial gene like many other restorer genes.
