FERTILITY RESTORER GENE AND FERTILITY RESTORATION METHOD FOR CW-TYPE MALE STERILE CYTOPLASM OF RICE

摘要

PROBLEM TO BE SOLVED: To provide a technique for directly identifying the genotype at locus Rf17 on the basis of the specific base sequence data thereof, and to provide a technique for artificially constructing a fertility restoration line.SOLUTION: The invention provides a method of restoring the fertility of CW-type cytoplasmic male sterile rice by inhibiting or reducing the expression of a gene comprising a specific base sequence, and a base sequence which can recover the fertility of CW-type cytoplasmic male sterility rice which is a nucleic acid having a base sequence selected from the following groups: (a) a base sequence having at least base sequences at positions 1611th to 4835th in other specific base sequences (4871 base length); and (b) a base sequence showing 95% or more sequence identity to the base sequence (a).
