FIG 4.

Phylogenetic tree based on the occurrence and amino acid sequence of 120 marker genes from Chthoniobacterales. MAGs available at GTDB as well as the “Ca. Udaeobacter copiosus” and the here assembled MAG were considered. The neighbor-joining tree was rooted on Escherichia coli UMN026 marker gene sequences. Red branches indicate the verrucomicrobial genus AV55 classified by GTDB, and the red diamond highlights the here-assembled “Ca. Udaeobacter” sp. MAG. Bootstrap values ≥50 calculated based on 500 iterations are shown at the branching points, and the bar represents 0.05 changes per amino acid position. All positions with less than 90% site coverage were eliminated.
