Abstract
This invention relates to a gene associated with male fertility, labeled Ms41-A, and a recessive mutant form thereof, labelled ms41-A, which confers male sterility. The Ms41-A gene is isolated from Arabidopsis, while the related gene Zm41-A is isolated from maize. Male-sterile plants are useful for the production of hybrid plants by sexual hybridization.
Claims24
An isolated nucleic acid molecule which comprises nucleotides having a sequence which:
- a) encodes a Ms41-A protein from Arabidopsis;
- b) encodes the Z31 protein (SEQ ID NO:29) or the Zm1-A protein (SEQ ID NO:30) of FIG. 14;
- c) comprises the sequence of FIG. 15 (SEQ ID NO:31);
- d) comprises the sequence of FIG. 16 (SEQ ID NO:32);
- e) comprises the sequence of FIG. 12 (SEQ ID NO:28), or a sequence which codes for the same amino acid sequence as the sequence of FIG. 12;
- f) hybridizes under highly stringent conditions to the nucleic acid of a), b), c), or d), with the proviso that the hybridizing sequence is not the EST sequence from rice having Genbank Accession No. D40316;
- or
- g) hybridizes under highly stringent conditions to the coding region of the nucleic acid sequence of FIG. 12, with the proviso that the hybridizing sequence is not the EST sequence from rice having Genbank Accession No. D40316.
A plant cell comprising a transposon in a gene thereby inactivating the gene, wherein the gene comprises nucleotides having the sequence shown in FIG. 3 (SEQ ID NO:11), FIG. 12 (SEQ ID NO:28), FIG. 15 (SEQ ID NO:31), or FIG. 16 (SEQ ID NO:32);
- or a coding sequence which hybridizes under highly stringent conditions to the sequence shown in FIG. 3 (SEQ ID NO:11), FIG. 15 (SEQ ID NO:31) or FIG. 16 (SEQ ID NO:32);
- or a sequence which hybridizes under highly stringent conditions to the coding region of the sequence shown in FIG. 12 (SEQ ID NO:28).
