abstract = {Chilling injury is a physiological disorder that appears when zucchini fruit is stored at low temperatures, causing
a severe diminution of the quality and nutraceutical value. Abscisic acid (ABA) has been proven to be a key
natural agent preventing low-temperature damage. This work aimed to elucidate the changes in exocarp metabolites
of zucchini fruit during cold storage and the mechanisms underlying the protective effects of ABA
through an untargeted metabolomics approach. A time-dependent metabolic modulation could be observed in
response to cold storage, where exogenously applied ABA elicited distinct metabolomic signatures. Supervised
statistics were then used to identify methyl jasmonate, heliespirone C, and (indol-3-yl)acetyl-L-phenylalanine as
the key compounds in the fruit exocarp having the highest discriminant ability. Noteworthy, the untargeted
phenolic profile of zucchini exocarps was also distinctively modulated amid the different treatments. Overall, the
implication of ABA in accumulating specialized metabolites, having a dual role in chilling injury mitigation
during cold stress and increasing the nutraceutical properties of zucchini fruits, was observed.},
