Phylogenetic analysis of the family of Agenet/Tudor proteins in the plant kingdom. a Phylogenetic analysis represented as a simplified version of the neighbor joining (NJ) tree, with 416 sequences of proteins from 31 species, from green algae to angiosperms. The tree was divided into three clades: a) the Derived clade, containing 279 sequences from 26 species, that harbor Agenet/Tudor domains combined with BAH, DUF724, F-box and other domains; b) the Intermediate clade, containing 111 sequences from 25 species, that harbor repetitions of Agenet/Tudor domains at N-term or central, combined or not with ENT domain; c) the Ancient (basal) clade, containing 29 sequences from 20 species, harboring one Agenet/Tudor domain in the C-term. b Schematic representation of the distribution of members of the Agenet/Tudor Family, the diversity of co-occurring domains and their phylogenetic relationships. There were 442 sequences of 33 species in 24 families from green algae to angiosperms. The squares represent the domains present in the proteins and the colors specify the domains according to the legend. A few rare domains are not represented. The species are listed in Additional file 7
