Figure 1From: Comparative analysis of function and interaction of transcription factors in nematodes: Extensive conservation of orthology coupled to rapid sequence evolutionTF-encoding genes in C. elegans , C. briggsae and C. remanei . The total number of TF genes in each of the species is given inside the brackets. The numbers of divergent TF genes and those conserved among the three nematode species are shown along the vertices and inside of the triangle, respectively.Back to article page
