摘要: 为了分离克隆与植物互作的大丽轮枝菌致病相关蛋白基因,利用 SMART 技术构建了大丽轮枝菌酵母双杂交 cDNA 文库。结果表明,构建的文库滴度为 5.2×107 cfu/mL,库容为 3.9×107 cfu;文库 cDNA 插入片段长度主要分布在 0.5~2.0 kb,平均为1 kb;文库重组率为 96%。表明文库质量较好,为筛选与植物互作的大丽轮枝菌致病蛋白基因奠定了基础。

Abstract: To seek out the V.dahliae proteins involved in the interaction of plant with V.dahliae, a yeast two-hybrid library of V.dahliae was constructed using SMART technique.Results showed that the titer of cDNA library was 5.2×107 cfu/mL, the library contained 3.9×107 cfu independent clones, the size distribution of insert fragments ranged from 0.5-2.0 kb, and the recombination rate was about 96%.These data demonstrated that the library could meet the requirements of standard cDNA library, which laid a foundation for screening the interaction proteins from V.dahliae.
