Abstract excerpt
Cotton fibers are initiated from the epidermal cells of the ovule before or on the day of anthesis. Gossypium arboreum SMA-4 mutant contains recessive mutation (sma-4(ha)) and has the phenotypes of fibreless seeds and glabrous stems. In this study, fine mapping and alternative splicing analysis indicated a nucleotide substitution (AG → AC) at splicing site in a homeodomain-leucine zipper IV family gene (GaHD1)...
