Patent

CA 2161515

A gene isolated from the cDNA library of a plant which encodes a protein MS2 involved in pollen development, said gene having the nucleotide sequence shown in Fig. 2 or a homologous gene. Also disclosed is a promotor of said gene having the nucleotide sequence shown in Fig. 3 or a homologous promotor. Further the invention discloses a recombinant polynucleotide which can be suitably used for obtaining a male-sterile plant, essentially comprising a) an inhibitor gene capable of inhibiting the expression of a target gene encoding the MS2 protein or a homologous target gene, and b) a promotor that is active in the tapetum of said plant.
