摘要:
以川山茶品种“茶睡莲”为试验材料,以改良CTAB法提取高质量DNA,采用正交设计L16(45),探讨了Mg2+、dNTPs、引物、TaqDNA聚合酶和模板DNA浓度对川山茶ISSR-PCR和SSR-PCR反应体系的影响。建立了相关优化体系:20 μL的ISSR-PCR扩增体系中含20 ng 模板DNA,2 μL10×Buffer,2 mmol/L Mg2+,0.15 mmol/L dNTPs,0.6 μmol/L引物和1 U TaqDNA聚合酶,扩增退火温度为55 ℃,35个循环;20 μL的SSR-PCR扩增体系中含50 ng模板DNA,2.5 mmol/L Mg2+,0.05 mmol/L dNTPs,0.2 μmol/L引物和0.5 U TaqDNA聚合酶,最佳退火温度为52 ℃,最佳循环数为38。应用该优化体系,分别用27个川山茶品种DNA进行了ISSR-PCR扩增和SSR-PCR扩增,结果显示,建立的优化体系具有较高稳定性。
Abstract:
To obtain stable ISSR-PCR and SSR-PCR amplification systems of Camellia japonica , the optima were explored by the orthogonal design in 5 factors (DNA template, Mg2+, dNTPs, primers and Taq DNA polymerase) at 4 levels with variety ‘Chashuilian’ as tested material. The experimental results showed that the optimized ISSR-PCR system for Camellia japonica ‘Chashuilian’ was established as follows, 20 ng DNA template,2 μL 10×Buffer, 2 mmol/L Mg2+, 0.15 mmol/L dNTPs, 0.6 μmol/L primer and 1 U Taq DNA polymerase and the optimal annealing temperature was 55 ℃ for UBC853 primer. And the optimized SSR-PCR system was established as follows,50 ng DNA template,2 μL 10×Buffer, 2.5 mmol/L Mg2+, 0.05 mmol/L dNTPs, 0.2 μmol/L primer and 0.5 U Taq DNA polymerase and the optimal annealing temperature was 52 ℃ for A55 primer. After 27 cultivars of Sichuan Camellia were used to test the stabilization of the optimized reaction system, respectively, the results indicated that the optimized reaction system was very stable.
