A fertility restoration gene in wheat and uses thereof, belonging to the field of plant biotechnology, specifically relating to the cloning of a recessive nuclear male sterility gene and a promoter thereof, and uses thereof in hybrid breeding. The fertility restoration gene FRG1 was successfully cloned by flow cytometry and high-throughput sequencing. The FRG1 gene can completely restore the male fertility of a Lanzhou genic male sterile mutant or allelic mutants thereof, which lays a foundation for the construction of a new wheat hybrid breeding technology system, meanwhile, which provides more possibilities to solve the technical bottlenecks of “three lines” and “two lines” hybridization technology of wheat, such as unstable fertility of sterile lines, limited resources for hybrid variety, the complexity of seed production technology and the high cost of seed production. The provided gene and method for propagation and maintenance of the sterile line have important significance and application value for hybrid breeding in wheat.
A fertility restoration gene, wherein a nucleotide sequence of the fertility restoration gene is selected from one of the following groups of sequences:
An expression cassette, the expression cassette comprises a fertility restoration gene, wherein a nucleotide sequence of the fertility restoration gene is selected from one of the following groups of sequences:
A method for regulating plant fertility, comprising transforming a fertility restoration gene to a Lanzhou genic male sterile mutant or an allelic mutant thereof, and restoring the male fertility of the Lanzhou genic male sterile mutant or the allelic mutant thereof, wherein a nucleotide sequence of the fertility restoration gene is selected from one of the following groups of sequences:
