Evaluation of the Resistance and Differential Induction of Chitinases in Tomato in Response to Inoculation with Fusarium oxysporum f. sp.lycopersici

Fusarium oxysporum f. sp. lycopersici (FOL) causes Fusarium wilt in tomato, a disease that significantly affects its production. This project investigated the response of different tomato genotypes to Fusarium wilt, aiming at selecting sources of resistance, as well as identifying the differential chitinase secretion during infection between resistant and susceptible cultivars. Results show that the BHRS cultivar proved to be resistant to the disease and there was increased chitinolytic activity in the roots of this genotype six days after inoculation (dai).
