Rice male fertility regulatory gene, mutant of rice male fertility regulatory gene, use thereof and a method for regulating rice fertility

Abstract

The present invention relates to the technical field of biology, in particular to a rice male fertility regulatory gene, the use thereof and a method for regulating rice fertility by means of using CRISPR-Cas9, and a mutant of the rice male fertility regulatory gene and a molecular marker and the use thereof. The present invention provides a rice gene GMS2 with the functions of regulating male germ cell development in rice and pollen fertility. The mutant of a rice male fertility regulatory protein GMS2 provided by the present invention can make rice pollen completely sterile, resulting in rice male sterility. The rice gene GMS2 and the mutant thereof, provided by the present invention, can be used in the sterile seed production and manufacturing of rice hybrids, thereby possessing both great application value and economic value.
