| Research Abstract |
We have made a collection of non-pathogenic <i>F. oxysporum</i> isolates from wild and transition tomato species in Andean Peru, Chile and Mexico. The isolates were subjected to phylogenetic analyses. We concluded that 'the ancient tomato wilt pathogen was non-pathogenic <i>F. oxysporum</i> associated with wild tomato species, and after domestication of tomato in Mexico the non-pathogenic isolates obtained pathogenicity maybe by gaining pathogenicity-related small chromosome.
