Abstract
Plant development can be altered by transforming a plant with a genetic construct that includes regulatory elements and DNA sequences capable of acting in a fashion to inhibit pollen formation or function, thus rendering the transformed plant male-sterile. In particular, the present invention relates to the use of an anther-specific promoter, designated 5126, and its operable linkage to a dominant negative gene, more particularly an exogenous methylase gene or DAM methylase gene, to achieve male sterility.
Claims5
A method of producing a male sterile plant, comprising the steps of:
- (a) providing a transformed plant that contains a recombinant DNA molecule comprising
- (i) a DNA sequence encoding a gene product which inhibits pollen formation or function and
- (ii) a 5126 promoter that is operatively linked to said DNA sequence encoding said gene product;
- and
- (b) growing said plant under conditions such that male sterility is achieved as a result of the expression of said DNA sequence.
A plant comprising a recombinant DNA molecule comprising
- (i) a DNA sequence encoding a gene product which inhibits pollen formation or function and
- (ii) a 5126 promoter that is operatively linked to said DNA sequence encoding said gene product.
