Fig. 1. Pictorial explanation of coevolution of the tomato wilt fungus, Fusarium oxysporum f. sp. lycopersici (FOL), and the tomato. The origin of FOL was the mutualistic nonpathogenic F. oxysporum that existed with the wild tomato in the Andes. During breeding, FOL emerged from the mutualistic nonpathogenic F. oxysporum by gaining accessory chromosomes carrying pathogenicity-related genes. The divergence of races in FOL occurred via mutations in avirulence genes (Table 2).
