摘要：
Nucleotide sequences mediating male fertility in plants are described, withDNA molecule and amino acid sequences set forth. Promoter sequences and theiressential regions are also identified. The nucleotide sequences are usefulin mediating male fertility in plants. In one such method, the homozygous recessivecondition of male sterility causing alleles is maintained after crossing witha second plant, where the second plant contains a restoring transgene constructhaving a nucleotide sequence which reverses the homozygous condition. The restoringsequence is linked with a hemizygous sequence encoding a product inhibitingformation or function of male gametes. The maintainer plant produces only viablemale gametes which do not contain the restoring transgene construct. Increaseof the maintainer plant is also provided by self-fertilization, and selectionfor seed or plants which contain the construct.
