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.
