摘　　要：以高抗青枯病的茄子高代自交系‘Q31-1’为试材,采用同源重组法构建了感染青枯病原菌R.solanacearum的茄子根部酵母双杂交cDNA文库,以期为研究茄子（Solanum melongena L.）与青枯病病原菌R.solanacearum的互作机制奠定基础。结果表明：文库库容大于1.25×10^7 CFU,平均插入片段大于1.5kb,随机挑选24个单克隆进行PCR检测,阳性率为100%。表明该文库可用于进行下一步互作蛋白筛选的研究。Taking ‘Q31-1＇eggplant as test material,the yeast two hybrid cDNA library was constructed after the eggplant inoculation with R.solanacearum,in order to research the interaction mechanism between the eggplant and R.solanacearum.The results showed that the library contained 1.25×10^7 CFU with 100%recombination rate based on 24 randomly selected clones.The result of PCR showed that length of insert cDNA fragments was greater than 1.5kb.The results demonstrated that the library could be used to screen the interaction protein.
