Nucleic Acid Molecules And Their Use In Plant Sterility


The present invention provides a method for disrupting pollen development in a plant, the method comprising inhibiting the expression of an endogenous nucleic acid molecule which is, under normal conditions, detectably expressed in anther tissue of a plant during pollen formation, and which codes for a protein belonging to the MYB class of DNA binding transcription factors. Particularly, the nucleic acid molecule whose expression is blocked encodes MYB 32 or MYB 103. The invention also provides nucleic acid molecules for use in the method, use of the method in producing male sterile plants and transgenic plants produced in accordance with the method.
