Zetaproteobacteria-dominated Fe mat paired metagenome and metatranscriptome

Paired metagenome and metatranscriptome sample from an Fe mat at Loihi Seamount, Hawaii. The microbial community was dominated by the Zetaproteobacteria at 94.4% (DNA) and 90.5% (RNA). We use these paired samples to show the high expression of putative Fe oxidase Cyc2 within the Zetaproteobacteria to highlight it''s importance in Fe mat systems.

来自夏威夷洛希海山（Loihi Seamount）铁垫的配对宏基因组（metagenome）与宏转录组（metatranscriptome）样本。该微生物群落的优势类群为ζ-变形菌纲（Zetaproteobacteria），在DNA层面占比94.4%，RNA层面占比90.5%。本研究利用该配对样本，证实ζ-变形菌纲内推定铁氧化酶Cyc2的高表达水平，以此凸显该酶在铁垫生态系统中的重要作用。
