The invention discloses a rice photo-thermo-sensitive male
sterility mutant Osgpat6.1, a corresponding
gene locus OsGPAT6.1 of the rice photo-thermo-sensitive male
sterility mutant Osgpat6.1 and application of a coding
protein of the rice photo-thermo-sensitive male
sterility mutant The phenotypic
gene OsGPAT6.1 for controlling the photo-thermo-sensitive male sterility of the rice is obtained by
cloning through
phenotypic analysis of a mutant and preliminary positioning of a
target gene, an
amino acid sequence of the phenotypic
gene OsGPAT6.1 is encoded as shown in SEQ ID NO.1 to form a
protein, and the gene affects the development process of rice
pollen by affecting tapetum degradation. The OsGPAT6.1 gene is subjected to gene editing, or a
mutant allele of the OsGPAT6.1 gene is introduced into a conventional rice variety in a hybridization manner, so that a photo-thermo-sensitive male sterile material for a two-line sterile line can be obtained. The gene and the encoding
protein thereof can be applied to creation of photo-thermo-sensitive sterile rice and
germplasm genetic improvement of the photo-thermo-sensitive sterile rice.
