Phylogenetic tree of a group of genes called Amt, found in SAR11 bacteria

Caption

The image shows the ‘phylogenetic tree’ of a group of genes called Amt, found in SAR11 bacteria. Different versions of these genes, which may influence how the bacteria take up and process nitrogen, are shown in different colors. Brown branches indicate core versions to the entire population, while green dots mark variants found in Mediterranean strains. The protein structures are also overlapped, highlighting that they all retain similar functions despite their differences. This genetic variation enables these bacteria to adapt to different marine environments.
