摘要: 采用cDNA-AFLP(cDNA-amplified fragment length polymorphism)技术,对小麦抗白粉病近等基因系Mardler/7*百农3217和百农3217材料的不同处理,于接菌后不同时间点的基因表达进行了表达分析。Mardler/7*百农3217及其感病轮回亲本百农3217在表达上存在差异;利用46对引物在抗/感近等基因系和感病轮回亲本DCINA处理发现283条差异带,对其中42条片段进行克隆测序,同源性分析发现包括信号转导相关的基因片段、与细胞壁的组成和结构相关的基因片段和与过敏性反应相关的基因片段。此研究结果发现其中的一些差异显示片段对小麦的抗白粉病机理的揭示具有重要作用。

关键词: 小麦, cDNA-AFLP, 差异表达

Abstract: To determine differential expression of genes between near isogenic line(NIL)Mardler/7* 3 Bainong 3217and Bainong 3217,cDNA2AFLP was employed to assay gene expressed in different time points after inoculation with pow2der and different treatments. Some differentially expressed genes were found in buds of Mardler/7* 3 Bainong 3217,Bain2ong 3217 and Bainong 3217 treated by DCINA on inoculated leaves. A total of 283 transcript2derived fragments(TDFs)were identified by using 46 pairs of primer combinations. Query in NCBI to 42 sequences out of 283 TDFs by BLASTXand BLASTN indicated that cDNA fragments show high homology to known genes,which mainly involve in signal trans2duction,cell components and oxidative stress. This research indicated that some TDFs were very important to understandthe wheat resistance to powder mildew.

Key words: Wheat, cDNA-AFLP, Differential display
