Abstract

The present invention relates to methods to limit or eliminate migration of pollen and seeds from transgenic plants into wild plant populations by producing sterile transgenic plants capable of achieving full vegetative growth. Specifically, the present invention provides targeted ablation of reproductive structures in plants by devising a promoter specific for carpel tissue and transforming plants with DNA constructs in which the promoter mediates expression of cytotoxic genes.
