  1. The genes unique to a strain and the gene content present at the same location in the other strain (plus ~ 500 bp either side of the locus) (Additional file 2: Table S4) are shown as the first and last columns. When no gene was present in a strain at the position of a unique gene in the other strain, ‘No’ was stated. The number of metagenomes analysed for each of the six lakes is shown in parentheses. Numbers in columns below each lake indicate the number of metagenomes that contained unique genes or the corresponding loci from the other strain, for ACAM34 (left column) and R1S1 (right column). Hlac_1060 is common in haloarchaea and has an ArsR-like helix-turn-helix domain (DNA-binding) that is often present in metal-regulated transcription regulatory proteins. Hlac_1975 has no identifiable domains (using InterProScan [66])
