A planktonic microbial community of a high altitute mountain freshwater lake Metagenome. freshwater metagenome

Our previous 16S rRNA gene clone library analysis discovered novel freshwater SAR11 bacteria in Lake Qinghai, a high-altitude mountain lake on the Tibetan Plateau; however, differences in gene content between the freshwater bacteria and other SAR11 ones and what functional genomic potential relates to the ecological niche of the bacteria remain unknown. To address these issues, we performed metagenomic analysis of planktonic samples over the whole lake area at different depths (0.5 to 22 meter).

本课题组前期通过16S rRNA基因克隆文库分析，在青藏高原的高海拔山地湖泊青海湖中发现了新型淡水SAR11细菌；然而，这类淡水细菌与其他SAR11类群的基因组成差异，以及哪些功能基因组潜力与该细菌的生态位相关，目前仍尚不明确。为解决上述科学问题，本研究针对青海湖全湖区不同深度（0.5至22米）的浮游生物样本开展了宏基因组分析。
