Fig. 1From: Genomic and transcriptomic insights into methanogenesis potential of novel methanogens from mangrove sedimentsCo-occurrence network reconstructed based on 16S rRNA gene sequencing data. Different color nodes represent OTUs affiliated with different lineages. Lines (edges) connecting the nodes represent strong (r > 0.6) and significant (P < 0.01) positive correlations. O/R value is the ratio of observed to random co-occurrence incidence between two lineages (methanogens and archaeal phyla or bacterial genera). O/R values of more than 1 indicate a non-random association between two lineagesBack to article page
