Phylogenetic analysis of conserved genes in TOGA. Sequences were collected from TIGR Orthologous Gene Alignment (TOGA) representing (A) plants, fungi, and metazoa, (B) plants only, and (C) metazoa only, trimmed to their matching regions, concatenated, aligned, and used to construct phylogenetic trees. As expected, the alignments derived from TOGA allow a faithful reconstruction of the known evolutionary relationships between these species.
