Gene Expansion Shapes Genome Architecture in the Human Pathogen Lichtheimia corymbifera: An Evolutionary Genomics Analysis in the Ancient Terrestrial Mucorales (Mucoromycotina)

Figure 4

Gene expansions and tandem duplications found in L. corymbifera.

(A) Tree representing an expansion of HET proteins in L. corymbifera. Branches enclosed in the grey shaded area represent paralogs of L. corymbifera. The black square represents the point where the expansion started. (B) Number and size of gene expansions in the L. corymbifera genome. (C) Main functional domains of gene expansions based on PFAM annotation. The numbers of genes with the different functional domains were combined if a domain was present in more than one expansion. (D) Proportion of genes within gene expansions which are arranged in tandem duplications. Each bar represents an expansion with the red part as the percentage of tandem duplicated genes (left). Clustering of tandem duplicated genes of cytochrome P450 genes in L. corymbifera (based on reconstruction with RaxML [130]). Red branches represent tandem duplicated genes. Numbers at the branch tips indicate different tandems.
