中文摘要:

【目的】 为筛选西花蓟马Frankliniella occidentalis与番茄斑萎病毒的互作蛋白。【方法】 利用Make Your Own“Mate & Plate™”Library System构建西花蓟马酵母双杂交初级cDNA文库以及Y187酵母次级文库,利用Matchmaker Gold Yeast Two-Hybrid System构建TSWV膜蛋白GN及GC诱饵载体。【结果】 建立的西花蓟马初级cDNA文库库容为5.6×106 cfu,其插入片段平均长度大于1 000 bp,重组率约为100%。建立的Y187酵母次级文库转化效率为5×106 cfu/μg,文库滴度为2.97×108。构建的pGNKT7-GN及pGBKT7-GC诱饵载体能够在Y2HGold酵母菌株中正确表达,无自激活活性且无毒性。【结论】 成功构建了西花蓟马酵母双杂交文库以及番茄斑萎病毒膜蛋白诱饵载体,可用于后续筛库实验。

英文摘要:

[Objectives]  To screen proteins involved in the interaction between western flower thrips and the Tomato spotted wilt virus (TSWV). [Methods]  A western flower thrip cDNA library and a Y187 yeast library were constructed using the Make Your Own “Mate & Plate™” Library System, and TSWV GN and GC bait vectors were constructed using the Matchmaker Gold Yeast Two-Hybrid System. [Results]  The capacity of the western flower thrip cDNA library was 5.6×106 cfu,the average library recombination rate was about 100%, and the average amplification sizes of insert fragments in the cDNA library were above 1 kb. The transformation ratio and titer of the Y187 yeast library were 5×106 cfu/μg and 2.97×108, respectively. The constructed pGNKT7-GN and pGBKT7-GC bait vectors were well expressed in yeast and had no self-activation and toxicity. [Conclusion]  A western flower thrip yeast library and TSWV membrane protein bait vectors were successfully constructed and can be used for further hybrid library screening.
