This study was carried out with the purpose of looking into the regulation of gene related to anther development, and applying their promoter to induce male sterile plants and restore their fertility. Progenies of transgenic male sterile tobacco plants containing anther specific promoter (BAN215) and diphteria toxin A (DTx-A) gene were analyzed by danamycin screening and pollen observation. DTx-A gene in male sterile plants was confirmed by PCR with the two synthetic primers, 5'-AACTTTTCTTCGTACCAC-3' and 5'-GCTTTCGCCTGTTCCCAG-3', from the sequence of DTx-A genes. The fragment of 350bp was appeared when the PCR product of 428 bp was digested with Rsal. pDTx-2 containing DTx-A gene was used as a control (DTx). Some of them were double transformed with the construct of BAN215 promoter and antisense DTxA (pKDA215b) to test restoration of fertility.
