Distribution of the FoToml gene encoding tomatinase in formae speciales of Fusarium oxysporum and identification of a novel tomatinase from F. oxysporum f. sp. radicis-lycopersici, the causal agent of Fusarium crown and root rot of tomato



Distribution of the FoToml gene encoding tomatinase in formae speciales of Fusarium oxysporum and identification of a novel tomatinase from F. oxysporum f. sp. radicis-lycopersici, the causal agent of Fusarium crown and root rot of tomato



Journal of General Plant Pathology 70(4): 195-201



The antifungal glycoalkaloid alpha -tomatine accumulates in tomato plants and may protect plants from fungal infection. Fusarium oxysporum f.sp. lycopersici, the causal agent of vascular wilt of tomato, produces a tomatinase (FoToml) that degrades alpha -tomatine to the nontoxic compounds tetrasaccharide lycotetraose and tomatidine. Induction of tomatinases and the distribution of FoToml homologues were examined among 30 strains belonging to 16 formae speciales of F. oxysporum.
