Protein involved in restoration of cytoplasmic male sterility to fertility and gene encoding the protein and gene

摘要

The object of the present invention is to isolate Rf gene, particularly Rf1 gene derived from radish, and identify its structure. The present invention provides a protein involved in restoration of a cytoplasmic male sterile individual to fertility which has 14 or more pentatricopeptide repeat (hereafter may be abbreviated to PPR) motifs, wherein a group of the motifs is divided into 3 or more blocks, each of the individual blocks has at least 2 or more PPR motifs, and the block in a carboxyl terminal (C terminal) side has 4 PPR motifs.
