Defect in BrMS1, a PHD-finger transcription factor, induces male sterility in ethyl methane sulfonate-mutagenized Chinese cabbage (Brassica rapa L. ssp. pekinensis)
Male sterility is an ideal character for the female parent in commercial hybrid 5 Piece Sectional seed production in Chinese cabbages.We identified three allele male sterile mutants msm2-1/2/3 in progenies of ethyl methane sulfonate mutagenized Chinese cabbage.It was proved that their male sterilities were controlled by a same recessive nuclear gen
