Abstract

See full text

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. The level and/or activity of a polynucleotide that influences male fertility is modulated in a plant or plant part. Regulatory sequences drive expression in a male-tissue-preferred manner and may be targets to downregulate an operably linked gene. Methods to track mutations that induce nuclear recessive male sterility in subsequent selfing and crossing of wheat lines containing the mutations are also provided. Male-sterile plants may be maintained by pollinating with a maintainer plant.
