摘要:

目的构建烟曲霉kipA基因突变株。方法通过In-Fusion技术将kipA基因的上下游基因与抗性基因顺序链接,以潮霉素抗性基因替换靶基因,达到用同源重组手段敲除烟曲霉kipA基因的目的,以realtime-PCR对基因突变株进行鉴定和验证。结果 RT-PCR结果显示,成功构建烟曲霉kipA基因突变株。结论烟曲霉kipA基因突变株的构建,为后续烟曲霉极性生长与血管侵袭性的研究提供了实验基础。

关键词: 烟曲霉, kipA基因, 极性生长

Abstract:

Objective To construct the kipA mutant strain.Methods The vector containing upper and downstream genes of kipA linked with hygromycin resistance gene in the middle was constrctied via In-Fusion assembly.The kipA gene of Aspergillus fumigatu was replaced with hygromycin resistance gene via the method of homologous recombination.The mutant strain was identified and validated by realtime-PCR.Results The kipA deletion strains were successfully constructed.Conclusions Successful construction of kipA mutant strain would provide the foundation for the research of polarized growth and vascular invasion of Aspergillus fumigatus.

Key words: Aspergillus fumigatus, kipA gene, polarized growth
