ISOLATED DNA ELEMENTS THAT DIRECT PISTIL-SPECIFIC AND ANTHER-SPECIFIC GENE EXPRESSION AND METHODS OF USING SAME

摘要

Isolated DNA elements that direct either pistil-specific or anther-specific expression of a polypeptide-encoding gene are disclosed. Plants comprising the DNA fragment operably linked to a gene are also disclosed. A further embodiment comprises a method of producing a female sterile plant, the method comprising growing a plant having integrated into its genome an isolated DNA element that directs pistil-specific expression of a nucleotide sequence that encodes or is transcribed into a moiety that causes female sterility in plants.
