Abstract:

Fusarium rot of muskmelon fruit, caused by Fusarium sulphureum, is a typical postharvest decay that not only seriously influences fruit quality but also leads to neosolaniol (NEO) contamination. Therefore, reducing muskmelon postharvest disease and NEO accumulation are of paramount importance. In the present study, the inhibitory effect of acetylsalicylic acid (ASA) against Fusarium rot and NEO accumulation in muskmelon fruits and its potential mechanism of action were investigated. The results indicated that 4 mmol/L ASA effectively inhibited Fusarium rot development and NEO production. Further investigation suggested that the possible mechanism was the activation of polyphenol oxidase (PPO), peroxidase (POD), phenylalanine ammonialyse (PAL), cinnamate-4-hydroxylase (C4H) and 4-coumarate-CoA ligase (4CL) and their corresponding gene expression, which resulted in the accumulation of total phenols and major synthesis substrates cinnamic acid, p-coumaric acid, caffeic acid, ferulic acid and erucic acid, and in the accumulation of lignin and major synthesis substrates p-coumarin, coniferol and sinadiol involved in phenylpropane metabolism. Moreover, ASA stimulated the expression of the pathogenesis-related proteins chitinase (CHT) and β-1,3-glucanase (GLU). These results suggest that ASA application could inhibit Fusarium rot and NEO accumulation by activating phenylpropane metabolism and pathogenesis-related proteins in inoculated muskmelon fruits.
