Abstract
Fusarium oxysporum f.sp. lycopersici Snyd. et Hans.(Fol) is a soil-borne plant pathogen that causes wilt in tomato plants and threatens tomato industry worldwide. Successful plant infection and tissue colonization by Fol is an active process that involves a variety of cell wall-degrading enzymes (CWDE), regulation of nutrient metabolism, and secretion of effectors to suppress and/ or overcome the physical basal defense in tomato plants. The effector-encoding avirulence genes have been identified and their combinations in the genome of Fol determine the 3 races of the pathogen. Avirulence genes and other pathogenicity factors are assembled in a lineage-specific genomic region, including 4 entire chromosomes that Fol acquired probably by horizontal gene transfer from other closely related species. In the course of co-evolution with Fol, tomato evolved 3 resistance genes to counteract pathogen effector-triggered disease. The interactions between tomato and Fol has become a model system for the study of the molecular basis of disease resistance and susceptibility in plants.
