Figure 3: The duplicated genes derived from tandem duplication and whole-genome duplications in Brassica genomes.
From: The Brassica oleracea genome reveals the asymmetrical evolution of polyploid genomes
(a) A Venn diagram showing shared and specific tandem duplication events in A. thaliana, B. rapa and B. oleracea. (b,c) Distribution of tandem genes and WGT/WGD-derived paralogues in the KEGG pathway maps in B. oleracea (bol), B. rapa (bra) and A. thaliana (ath). For each KEGG pathway map, the proportion of the number of duplicated genes or paralogues to the total genes was calculated (x axis) and the number of maps whose tandem gene proportion fell in a range was shown on the y axis. (d) Oxidative phosphorylation pathway enriched by WGT-derived paralogous genes in the Brassica genomes. The gene copy number for each KO enzyme in B. oleracea, B. rapa and A. thaliana were shown (dash-connected) under the KO enzyme number.
