Table S6. Significant correlations between major methanogen genera in the metagenomic samples and the compositional change of DOM. Pearson’s correlation coefficient tests were performed between major taxonomic groups of methanogens in the metagenomic samples and the compositional change of DOM along first canonical axis obtained from canonical correlation analysis (CCorA). CCorA was performed using the first five principal coordinate (PCo1–5) axes of DOM composition and PCo1–2 axes of FOAM orthologs. It resulted in two canonical axes (P < 0.01, chi-square test) along which significant correlations were observed between functional potentials and DOM composition (P < 0.013). Only taxa with significant correlations (P < 0.05) were shown here. MeNH2 is methylamine. Parentheses means utilized by some, but not all species or strains. (XLSX 12 kb)

补充表S6：宏基因组样本中主要产甲烷菌属与溶解有机质（Dissolved Organic Matter, DOM）组成变化间的显著相关性。
本研究针对宏基因组样本内的主要产甲烷菌分类群，与通过典型相关分析（Canonical Correlation Analysis, CCorA）得到的第一典型轴对应的DOM组成变化，开展了皮尔逊相关系数检验。
典型相关分析采用DOM组成的前5个主坐标（Principal Coordinate, PCo）轴（PCo1–5）以及FOAM同源基因的前2个主坐标轴（PCo1–2）进行构建。
本分析最终得到2个典型轴（卡方检验P < 0.01），在此轴上观测到功能潜力与DOM组成间存在显著相关性（P < 0.013）。
本研究仅展示了具有显著相关性（P < 0.05）的分类群。
