摘要:
[目的]揭示古菌在五大连池火山区的生态格局。[方法]系统,解析五大连池火山喷发沉积物中古菌的群落组成和分布规律。[结果]研究发现,五大连池火山区沉积泥中包含Thaumarchaeota(奇古菌门)、广古菌门(Euryarchaeota)和泉古菌门(Crenarchaeota),其中奇古菌门丰度最高,主要包括SAGMCG - 1与Thaumarchaeota Incertae Sedis两大类群;广古菌门主要甲烷微菌纲(Methanomicrobia)、甲烷杆菌纲(Methanobacteria)、盐杆菌纲(Halobacteria)、热原体纲(Thermoplasmata)和甲烷球菌纲(Methanococci),其中甲烷微菌纲(Methanomicrobia)是优势种群,下分7目,13科,23属,多样性丰富;泉古菌门主要为热变形菌纲(Thermoprotei)与SCG类群。奇古菌门广古菌门[结论]五大连池火山沉积环境中含有丰富的古菌资源,显著异于报道较多的陆地土壤及海底沉积环境该研究为今后挖掘功能性种质资源及探讨古菌群落在火山环境中的生态规律奠定了科学基础。(图7 表2 参31)
Abstract:
This study aimed to revealing the ecological pattern of the archaea in Wudalianchi volcanic region. High-throughput?sequencing?technology for the Illumina MiSeq System and phylogenetics were used to analyze the community constitution and distribution of the archaea in volcanic sediment of the Wudalianchi. The results showed that three categories of Thaumarchaeota, Euryarchaeota and Crenarchaeota have been analyzed, among the abundance of Thaumarchaeota was the highest, mainly including SAGMCG-1 and Thaumarchaeota Incertae Sedis; Within the Euryarchaeota, Methanomicrobia, Methanobacteria, Halobacteria, Thermoplasmata and Methanococci were abundant, with Methanomicrobia to be the predominant class which can be divided into 7 orders, 13 families, 23 genus, and be rich?in?biodiversity; Thermoprotei and SCG were the main classes belonging to Crenarchaeota. In addition, Crenarchaeota was closer to Thaumarchaeota, which was far away from Euryarchaeota based on evolutionary tree. There was a certain similarity with Huoshao volcano and Yaoquan volcano, Jiaodebu volcano and Longmen volcano, instead the others?showed different?degrees of?difference in community constitution of archaea in the different sedimentary environments. The results suggested that the microbial resources are abundant and there should be a plentiful new unknown taxon in volcanic sedimentary environment of the Wudalianchi, which significantly different from those of the reported land and marine sedimentary environment. The?research will laid?the?scientific?foundation for mining functional microbial resources and exploring the ecological regularity of the archaea community in volcanic environment in the future.
