Abstract

A fertility restorer gene (Rf-1) of [ms-bo] cytoplasmic male sterility (CMS) in rice has been reported to be responsible for the processing of RNA of aberrant atp6 of mitochondria. We have carried out map-based cloning of the Rf-1 gene and found that a 4.7-kb genomic fragment of a restorer line promoted the processing of aberrant atp6 RNA when introduced into a CMS line. The genomic fragment contained a single open reading frame encoding 18 repeats of the 35 amino acid pentatricopeptide repeat (PPR) motif. The cloned PPR gene is a possible candidate of Rf-1. A non-restoring genotype was identified to have deletions within the coding region.
