摘要:

以暗纹东方鲀基因组DNA为材料,利用正交设计L16(45)对影响暗纹东方鲀SRAP-PCR反应的5个因素(Mg2+、Taq酶、dNTPs、模板DNA、引物)在4个水平上进行正交组合,确立了暗纹东方鲀SRAP反应最佳体系为:20 μL的PCR体系中含有 Mg2+1.5 mmol ·L -1、Taq酶0.5 U、模板DNA 75 ng、dNTPs 0.15 mmol·L -1、引物0.2 μmol· L -1。利用30个暗纹东方鲀样本对该体系进行验证,结果表明该体系稳定可靠。

Abstract: Using genomic DNA of Takifugu obscurus, SRAP-PCR amplification system of Takifugu obscurus was optimized using orthogonal design based on five influencing factors of the amplification efficiency (Mg2+, Taq DNA polymerase, dNTPs, DNA template, primer) at four levels. The results showed that the optimal 20 μL SRAP-PCR reaction system contained Mg2+ 1.5mmol·L-1, TaqDNA polymerase 0.5 U, dNTPs 0.15 mmol·L-1, template DNA 75 ng and primer 0.2 μmol·L-1. The optimized SRAP\|PCR system was tested for 30 Takifugu obscurus germplasms and proved to be stable and reliable.

Key words: Takifugu obscurus, SRAP, orthogonal design, optimization
