Nucleotide sequences mediating male fertility and method of using same

摘要

Nucleotide sequences mediating male fertility in plants are described, with DNA molecule and amino acid sequences set forth. Promoter sequences and their essential regions are also identified. The nucleotide sequences are useful in mediating male fertility in plants.

1. A method of preferentially expressing a gene product in male tissue, comprising introducing into a plant an expression cassette comprising
(a) an isolated nucleic acid sequence comprising a polynucleotide selected from the group consisting of SEQ ID NO: 20 and functional fragments thereof, wherein said nucleic acid sequence confers male-tissue-preferred expression of an operably linked sequence; and (b) an operably linked sequence encoding a gene product.
