Figure 2From: Insight into transcription factor gene duplication from Caenorhabditis elegans Promoterome-driven expression patternsRepresentations of the molecular phylogenies of the C. elegans and C. briggsae members of the NK class of homeodomain (A), the forkhead (B), the CUT class of homeodomain (C) and the T-box (D) transcription factor gene families. C. briggsae genes are shaded in light grey and C. elegans genes are shaded in mid-grey.Back to article page
