COMPOUNDS AND CONSTRUCTS FOR PRODUCING MALE STERILE PLANTS

摘要

A method is described for inducing male sterility in plants which are capable of being genetically transformed. The plant is tranformed with a DNA-construct that combines a male-organ specific promoter with an enzyme which reacts with a protoxin to release, in the male-organ or gamete, a toxin for the male-organ or gamete. Also described is the DNA-construct, the protoxin, the transgenic plant containing the construct, seeds produced by the transgenic plant, a method for producing hybrid seed, seed progeny, and transgenic plants contacted with the protoxin.
