Figure 6.
F-box family genome positions. The genome positions of 27 highly conserved (red) and 415 unstable (blue) F-box-containing genes in C. elegans. Striking clustering is apparent only for the unstable genes, consistent with evolution by local gene duplication. Highly conserved genes include all 23 ortholog trios plus four genes that did not have specific one-to-one orthologs because of a single duplication or loss in one species. Gene bins are 100 kb in length, and the number of genes in the largest bin on each chromosome is indicated.
