摘要: 对我国昌黎产区5 家具有代表性酒庄进行酒类酒球菌(Oenococcus oeni)菌株的分离,采用Species-specific聚合酶链式反应(polymerase chain reaction,PCR)鉴定O. oeni,运用荧光标记扩增片段长度多态性(amplified fragment length polymorphism,AFLP)技术进行分子遗传学研究。结果表明:在分离具有表型差异的226 株葡萄酒乳酸菌中,通过Species-specific PCR,鉴定出222 株O. oeni。对分离的O. oeni菌株进行荧光标记AFLP分析,结果显示,经筛选的荧光标记选择性扩增引物可将222 株O. oeni分为221 个AFLP遗传型,其相似性系数在74%~98%。在81.7%的相似性水平上,分离菌株存在2 个主要的进化类群。分离自同一酒庄的O. oeni菌株种群形成了独特的簇群结构,呈现出遗传发育和分离起源的典型特异性关系,证实了O. oeni资源是葡萄酒“风土”的重要组成之一。本研究证实了昌黎产区存在丰富的O. oeni资源,且不同酒庄分离的O. oeni菌株种群呈现出遗传特异性,这为开发我国具有地域特色的O. oeni资源提供了技术和理论支持。

Abstract: 222 Oenococcus oeni strains isolated from 5 different wineries in Changli, Hebei province were identified by species-specific PCR, and amplified fragment length polymorphism (AFLP) technique was used for genetics research. The AFLP results showed that a total of 221 AFLP genotypes were detected in the 222 strains, with different phenotypes, and their similarity coefficients were 74%–98%, revealing a high level of genetic diversity. By the un-weighted pair-group method with Arithmetic means (UPGMA), two major phylogroups were deciphered at 81.7% similarity level. Additionally and more importantly, the strains from the same winery formed unique clusters, indicating distinct genetic relationships with their origins and validating that O. oeni is an important part of the wine terroir. This study confirmed that there are rich O. oeni resources with genetic specificity in the wine-making region of Changli. This study offers technical and theoretical support for the development of indigenous starter cultures with regional characteristics.

Key words: wine, Oenococcus oeni, amplified fragment length polymorphism, genetic diversity, genetic specificity, terroir
