Fig. 6: Notable functional gene gains during non-AOA Thaumarchaeotal evolution.
From: Genomics of soil depth niche partitioning in the Thaumarchaeota family Gagatemarchaeaceae

The gain of gene families in specific ancestors was predicted by comparing the probabilistic ancestral gene content reconstructions. Dots indicate branches with at least 95% UFBOOT and SH-aLRT support. Circled numbers indicate specific thaumarchaeotal ancestors. The numbers in parentheses correspond to the number of gene families of the named function gained in each ancestor. *The rbcL gene was slightly below the 0.5 reconciliation copies threshold (0.43), but we decided to retain it in the analysis.
