Abstract
Nucleotide sequences mediating male fertility in plants are described, with DNA molecule and amino acid sequences set forth. Use of the nucleotide sequences to mediate fertility in plants is also described. In one such method, an inducible promoter is used to regulate expression of the DNA molecule. The control sequences are modified so that it is normally "off" and as a result the plants are male sterile. When it is desired to reproduce the male sterile plants, male fertility is restored by treating the plants with a non-phytotoxic chemical which induces expression of the critical gene.
