Figure 1

Phylogeny of LIM homeobox genes. The maximum likelihood tree based on an alignment of two LIM domains and the homeodomain is shown here with support values from Neighbor-joining/Likelihood/Bayesian analyses shown for the major nodes (relationships within the major classes were well supported only for vertebrate sequences). Neighbor-joining and Likelihood bootstrap values above 50% are shown, as are Bayesian posterior probabilities above 0.95. Full trees from each analysis are shown in Additional file 1.
