摘要: [目的]建立适合海岛棉组织培养过程中差异基因表达研究的DDRT-PCR体系.[方法]试验选取海岛棉体胚发育过程中的胚性愈伤组织,无菌苗下胚轴为对照.对引物浓度、dNTP浓度、酶浓度和退火温度等影响差异显示PCR的关键因素进行单因素优化实验.[结果]确定了海岛棉组织培养差异显示PCR体系为(10 μL):cDNA 2 μL;dNTP 200 μmol/L;上游引物0.4 μL(10 μM),下游引物0.5 μL(10 μM);Taq酶0.5 U,Buffer1.0 μL.前5个循环退火温度为50℃,后30个循环退火温度为57.1℃.[结论]用该体系扩增,PCR产物特异性高,条带清晰,背景污染少.
