Figure 1From: Gene make-up: rapid and massive intron gains after horizontal transfer of a bacterial α-amylase gene to BasidiomycetesTree of glycosyl hydrolases of the GH13 family. Full gene and species names and taxonomic positions are given in Additional file 3: Table S3. GH13 subfamilies [58] are colour-labelled and indicated by their numbers next to the species names. The fungal genes studied in this work are indicated by an asterisk. Bootstrap values are shown along the branches.Back to article page
