From: Degeneration of aflatoxin gene clusters in Aspergillus flavus from Africa and North America
Heat map of SNP density (SNPs/kb of gene) in aflatoxin gene cluster of 17 non-aflatoxigenic and 3 toxigenic A. flavus genotypes. SNPs were called in reference to A. flavus AF13. Genotypes with a common letter along the bottom and genes with a common letter along the side do not differ significantly in mean SNP density by Tukey’s HSD test (P < 0.05). Only genotypes having all the genes in the aflatoxin biosynthesis cluster are included. Genotype names in bold are toxigenic. Schematic representation of the aflatoxin biosynthesis cluster is presented at the top. Left is the telomeric end of the cluster
