Characterization and transcriptome analysis of a dominant genic male sterile cotton mutant.

Abstract excerpt

BACKGROUND: Male sterility is an efficient trait for hybrid seed production and germplasm innovation. Until now, most studies on male sterility were on cytoplasmic and recessive genic sterility, with few on dominant genic male sterility, especially in cotton, due to lack of such mutant. RESULTS: We discovered a natural male sterile (MS) Sea Island cotton (G. barbadense) mutant. Genetic analysis showed the...
