Figure 4: Retention of duplicated genes according to biological criteria.

From: Global trends of whole-genome duplications revealed by the ciliate Paramecium tetraurelia

Figure 4

For each curve, a value of 1 means that the retention of duplicates in one particular category is equal to the mean retention for all the genes. Values below 1 indicate under-retention and values over 1 indicate over-retention. a, Retention rates for proteins forming known complexes in S. cerevisiae. Each point represents the ratio of duplicated to non-duplicated genes for genes in complexes in S. cerevisiae with orthologues in P. tetraurelia, divided by the ratio of total duplicated genes to non-duplicated genes for each duplication. The blue curve is for orthologues of the CYGD list (http://mips.gsf.de/), and the red curve is for orthologues of ref. 29. b, Retention of gene duplicates in central metabolic pathways: blue, amino-acid metabolism; red, carbohydrate metabolism; green, energy metabolism; orange, lipid metabolism; purple, nucleotide metabolism. Each point represents the ratio of duplicated to non-duplicated genes for genes with unambiguous EC number, divided by the ratio of total duplicated genes to non-duplicated genes for each duplication. c, Expression versus retention across the three WGDs. Each point represents the ratio of duplicated to non-duplicated genes for genes with a defined number of EST matches, divided by the ratio of total duplicated genes to non-duplicated genes for each duplication. Yellow, zero to two EST matches; orange, three to five EST matches; red, six to nine EST matches; purple, ten or more EST matches.
