Genomic organization of mating type genes, in three Verticillium species. In the V. longisporum genome sequences the mating type genes were identified on two different contigs in both VL strains. MAT1–1-1 (green), MAT1–2-1 (yellow) and neighboring genes (black). Dashed lines in different colors (blue, red, green, yellow, orange, purple and black) indicate homology among the genes. VDAG_JR2_Chr2g11850 (black) lacks the HMG-box conserved in other MAT1–1-1 proteins. Details on PFAM predictions and levels of sequence homologies are listed in Additional file 6. Gene ID is indicted. The illustration is not drawn to scale
