Abstract
The present study characterized a cell wall chitin from Saccharomyces cerevisiae and investigated the effect of a postharvest chitin treatment on disease resistance against Botrytis cinerea infection in tomato fruit and the possible mechanisms involved. The results indicated that treatment with chitin could effectively induce strong resistance against gray mold rot caused by B. cinerea in tomato fruit. Moreover, chitin treatment promoted the accumulation of ROS and callose deposition. The activities of six defense-related enzymes, including superoxide dismutase, catalase, peroxidase, phenylalanine ammonia-lyase, β-1,3-glucanase and chitinase, along with the expression of these corresponding genes, were markedly enhanced in the chitin-treated fruit. Meanwhile, the key enzyme genes of SA biosynthesis and signal transduction pathway were found up-regulated in the chitin treatment. Therefore, these results suggest that the increased disease resistance of tomato fruit after chitin treatment during storage might be attributed to an elicitation of defense response as mentioned above in fruit.
