摘要
桑天牛卵啮小蜂是抑制桑天牛的有效天敌。为使天敌能大量人工繁殖,从分子生物学角度对单头桑天牛卵啮小蜂基因组DNA的提取方法及RAPD反应条件进行了探索。结果表明,采用改良的SDS方法,提取的DNA质量较高,适宜于RAPD-PCR扩增分析。在25μL反应体系中,RAPD分析的优化反应体系为:1.5mmol/L Mg^(2+)、2μL的dNTPs(2.5mmol/L)、320nmol/L随机引物、80ng模板DNA、0.8U TaqDNA聚合酶。
Aprostocetus prolixus is an important natural enemy for Apriona gerrnari. In order to propagate more Aprostocetus prolixus, we studied the method of genomic DNA extraction and optimization of RAPD analytic conditions. The results showed that high grade genome DNA was obtained by the revised SDS method. The optimal PCR system for RAPD analysis was as follows: 1.5 mmol/L Mg^2+, 2 μLdNTPs(2.5 mmol/L), 320 nmol/L random primer, 80 ng DNA template, 0.8 U Taq polymerase, in 25 μL reaction system.
