Figure 2

Synteny and intron conservation of LIM homeobox genes. (a) Four of the six Trichoplax LIM homeobox genes are present on one scaffold, three of these are present in tandem. This tandem cluster also contains a gene coding for a protein of the LIM only (Lmo) class. This scaffold is in the same putative ancestral linkage group as human chromosome segments that contain 6 of the 12 human LIM homeobox genes. (b) Two introns that interrupt the homeodomain in the Lmx class proteins are well conserved across animals, but one has been lost in both Nematostella and C. elegans. Introns are represented with square brackets with the enclosed number indicating the phase of the intron.
