Abstract:
The present invention is directed to methods for producing plants containing alternate expression cassettes at a single locus in the plant genome. The two expression cassettes encode polypeptides which, when present in the same cell, are lethal to the cell. In preferred embodiments, the plant cell is an anther cell and the plant is male sterile.
