Abstract

Promoters from endogenous genes of plants are isolated, wherein said promoters direct gene expression selectively in stamen cells of said plant, particularly in tapetum cells of said plant. The promoters may be used to transform a plant with a foreign DNA sequence encoding a product which selectively disrupts the metabolism, functioning, and/or development of stamen cells of the plant.
