Fig. 6: Horizontal gene transfer of the archaellum machinery to Bacteria.
From: Structure of a functional archaellum in Bacteria of the Chloroflexota phylum
Phylogenetic tree of concatenated core archaellum machinery subunits. The maximum likelihood tree was inferred from a supermatrix of 431 sequences and 987 amino acid positions with the model LG + R10 + C60. The archaellum clade of Chloroflexota is well nested in Archaea with Methanomada as the closest relative. Archaellum gene clusters of representative archaellated species are shown coloured as in Fig. 2 indicating the presence of an arl2 cluster to Chloroflexota. Scale bar as indicated.
