摘要：
Compositions and methods are capable of modulating male fertility in a plant. Compositions comprise polynucleotides and polypeptides, and fragments and variants thereof, which modulate male fertility. Expression cassettes comprise a male-fertility polynucleotide, or fragment or variant thereof, operably linked to a promoter, wherein expression of the polynucleotide modulates the male fertility of a plant. Regulatory sequences drive expression in a male-tissue-preferred manner and may be targets to downregulate an operably-linked gene. Mutations that induce nuclear recessive male sterility in subsequent selfing and crossing of wheat lines containing the mutations may be tracked. Male-sterile plants may be maintained by crossing with a maintainer plant. Hybrids can be produced using the male-sterile plants.
