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。

关键词: 酒酒球菌, 抗酸相关基因, RAPD标记

Abstract:

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.

Key words: Oenococcus oeni, acid-resistant gene, RAPD markers
