From: Degeneration of aflatoxin gene clusters in Aspergillus flavus from Africa and North America
Plot of Ka/Ks values on Y-axis based on pairwise comparisons of orthologous genes from non-aflatoxigenic genotypes with A. flavus AF13. The length of coding sequence used to calculate Ka/Ks are as follow: cypA (390Â bp), aflR (334Â bp), estA (345Â bp), ver-1 (389Â bp), vbs (332Â bp), and cypX (327Â bp). Since not all genes are present in all genotypes, no values are present for the aflR and estA genes in DO38-B and for the cypA and aflR genes in GO18-2. Genotypes BA16-F, EC69-E and La3304 have complete sets of genes while genotypes DO38-B and GO18-2 have partially deleted aflatoxin gene clusters
