FIG 1 .
Heat maps of gene abundances of key functional groups in Rhodanobacter genomes and OR-IFRC metagenomes. Abundance is measured as relative abundance against all sequenced bacterial genomes and as the odds ratio of each COG number against all COG categories for the selected organism/community. Asterisks indicate significantly overabundant COGs (chi-square test and 1-tailed Fisher’s exact test). The x axis shows the biological samples, with “All Rhodanobacter” representing all Rhodanobacter genomes combined and red font indicating OR-IFRC isolates or metagenomes.
