Figure 4

Extent of conservation in coding regions compared to 12 reference organisms. To illustrate the degree of splicing conservation between coding regions in each organism and the 12 reference organisms, the most highly conserved genes are identified by conservation to 9 or more reference organisms. Additional categories in decreasing level of conservation are splicing conservation to 6 or more reference organisms, 3 or more reference organisms, and membership in an ortholog set. Reference species are listed before non-reference species.
