摘要: 采用改良CTAB法提取葡萄属22种植物的基因组DNA,对其完整性进行了测定,通过单因素五水平试验,筛选模板、Mg2+、Taq酶、dNTPs和随机引物的浓度及其用量,建立了葡萄RAPD技术最优体系,即25 μL体积中模板DNA为40 ng·μL-1,MgCl2 2.0 mmol·L-1,dNTP 0.8 mmol·L-1,Taq DNA 聚合酶1 U·μL-1,引物 0.8 μmol·L-1,建立了葡萄基因组DNA的RAPD 反应扩增程序,即94℃预变性4 min, 94℃循环变性 45 s,37℃退火 55 s,72℃ 延伸 80 s,40个循环,最后72℃ 延伸10 min。

Abstract: Using a modified CTAB method, genomic DNA was isolated from 22 grape cultivars and their integrality were analyzed. Content and dosage of template, primer, dNTPs, Mg2+ and Taq DNA polymerase were selected by single factor five level tests and the optimum RAPD systems for grape were established. The total reaction volume was 25 μL containing 40 ng·μL-1 template DNA, 2.0 mmol·L-1 MgCl2, 0.8 mmol·L-1 dNTP, 1 U·μL-1 Taq DNA polymerase, 0.8 μmol·L-1primers. The appropriate PCR procedure was 94℃ 4 min, l cycle; 94℃ 45 s, 37℃ 55 s, 72℃ 80s, 40 cycles; 72℃10 min.
