Phylogeny of annexins. Maximum-likelihood phylogenetic analyses of alpha-giardins and annexins from diplomonads and other eukaryotes were performed. (A) Phylogenetic tree based on the whole data set with the diplomonad part of the tree collapsed. The color coding is according to the classification into supergroups as follows (23): SAR, red; Archaeplastida, green; Excavata, brown; Amoebozoa, blue; Opisthokonta, purple. (B) Phylogenetic tree based on only the diplomonad sequences. The tree is rooted according to the diplomonad phylogeny, and the root of the diplomonad subtree is indicated by a filled circle. The color coding is according to species as follows: G. intestinalis, green; G. muris, red; S. barkhanus, blue; S. salmonicida, gray; S. vortens, purple; Trepomonas sp. strain PC1, brown. Only bootstrap support values of >50% are shown. For clarity, no bootstrap support values for bipartitions between G. intestinalis isolates are shown.
