摘要
对影响RAPD反应体系的主要因素进行优化,建立适合本实验室的RAPD反应体系。在此基础上以33株抗酸性酒酒球菌和9株酸敏性菌株为试材,采用BSA法和RAPD技术,通过对45个随机引物的筛选以及在单菌株中的筛选验证,最终获得与酒酒球菌抗酸性状相关的3个RAPD标记:S40-1400、S333-2500、S333-650。
Major factors affecting RAPD reaction system were optimized and an optimal RAPD reaction system was established for laboratory investigations.Subsequently,33 acid-resistant Oenococcus oeni strains and 9 acid-sensitive Oenococcus oeni strains were used as experimental materials for screening RAPD markers linked to acid resistance-related genes.Random amplified polymorphic DNA(RAPD) and bulked segregate analysis(BSA) techniques were employed in this study.Three RAPD markers S40-1400,S333-2500 and S333-650 linked to acid resistance in Oenococcus oeni were obtained through a selection from 45 random primers and confirmation in a single Oenococcus oeni strain.
