摘  要:
以大白菜基因组DNA为模板,对影响竞争性等位基因特异性PCR(Kompetitive allele specific PCR,KASP)的反应体积、引物浓度和DNA模板用量等3个参数进行优化,建立了适用于大白菜的KASP反应体系。96孔模块最佳反应体系中,总反应体积为8μL,其中模板DNA(60~80 ng·μL~(-1))1μL,KASP Master mix(2×)4μL,引物混合物(50μmol·L~(-1))0.14μL,ddH_2O 3μL。384孔模块最佳反应体系中,总反应体积为4μL,其中模板DNA(60~80 ng·μL~(-1))1μL,KASP Master mix(2×)2μL,引物混合物(50μmol·L~(-1))0.07μL,ddH_2O 1μL。利用不同引物和不同的大白菜材料对优化的反应体系进行验证,均获得了较好的KASP-SNP分型,验证了该优化体系的稳定性。该反应体系可以用于大白菜遗传多样性研究、基因定位、遗传图谱构建等遗传学研究。

摘  要:
In this study,the KASP(Kompetitive allele specific PCR)reaction system suitable for Chinese cabbage(Brassica rapa L. ssp. pekinensis)was established through optimization of three parameters(reaction volume,primer concentration and template DNA amount),which used genomic DNA from Chinese cabbage as template. The optimal KASP reaction system for 96-well plate format was as follows:total volume 8 μL,containing 1 μL template DNA(60–80 ng · μL~(-1)),4 μL KASP Master mix(2×),0.14 μL primer assay mix(50 μmol · L~(-1))and 3 μL ddH_2O. The optimal KASP reaction system for 384-well plate format was as follows:total volume 4 μL,containing 1 μL template DNA(60–80 ng · μL~(-1)),2 μL KASP Master mix(2×),0.07 μL primer assay mix(50 μmol · L~(-1))and 1 μL ddH_2O. With the optimal KASP reaction system,high quality results of KASP-SNP genotyping were produced on different Chinese cabbage accessions with different primers,which indicated the stability of the current system. The optimized KASP reaction system can be used in genetic study for Chinese cabbage,such as genetic diversity analysis,gene mapping and genetic map construction.
