Abstract: Elucidating the gene expression in anther development is one of the key steps to develop new types of male sterility. Four types of male sterile cabbage lines and their corresponding fertile lines were used to analyze the gene expression by cDNA-AFLP. In total, we got 113 differentially exp ressed TDFs, which were
classified into 12 group s. Among them, 76 TDFs (67.25% of the total) were classified into group A, B, C and D, which were sequentially interrupted according to the different sterile stages in four male sterile lines. Sequence analysis of representative TDFs from each group showed that glycosyl hydrolase family 1 protein, VQ motif-containing protein, glycine-rich protein and pectatelyase family protein possibly involved in sporogenesis cell, pollen mother cell, pretetrad and post-tetrad stage male development respectively.
