[Method] A B. juncea TGMS line K121S was selected as the experimental material. The total RNAs were isolated from fertile and sterile pollens at different development stages, including mother cell stage, tetrad stage, tricellular pollen stage and maturity stage. DDRT-PCR was carried out to identify differentially expressed genes. [Result] A total of 44 differentially expressed cDNA fragments were identified with Dot blot. And seven candidate genes related to fertility conversion of K121S were screened out by BLASTN, including callose synthase gene, aldehyde dehydrogenase gene and RNA polymerase I transcription factor RRN3 gene which were differentially expressed at the transcriptional level, H＇-ATPase gene, fructose diphosphate aldolase -class I gene, teucine-rich repeat receptor-Jike serine/threonine- protein kinase gene and alkaline/neutral invertase gene, which were differentially expressed at the post-transcriptional level. [Conclusion] The results of this study will help to explain the molecular mechanism of thermo-sensitive genic male sterility of B. juncea.展开更多
