TLDR
The use of physical, chemical, and biological inducers or elicitors to manage and control postharvest diseases is reviewed in this paper, which briefly presents current knowledge about elicitors and mechanisms of induced resistance in fresh fruits and vegetables.Abstract:
More than one-third of harvested fruits and vegetables are lost annually due to diseases caused by fungal pathogens in the field or after harvest, especially if produce sanitation and refrigeration are poor. Besides economic losses, some postharvest pathogens produce mycotoxins in fruits and vegetables that pose a potential threat to human and animal health. Application of synthetic fungicides is the primary strategy employed to control these diseases. However, rising concerns about fungicide residues, development of pathogen resistance to fungicides, and environmental pollution have encouraged the development of eco-friendly strategies to control postharvest diseases. Interest in induced resistance as a sustainable strategy to manage postharvest decay in fruits and vegetables has increased. Natural resistance to pathogen infection in horticultural products can be activated by various means. Physical inducers, such as UV-C irradiation and heat treatment, prime plant resistance through abiotic stress. Some chemical elicitors, such as salicylic acid, benzothiadiazole, 2,6-dichloronicotinic acid, and jasmonic acid, induce resistance in plants. Moreover, biological elicitors, such as harpin, chitosan, and some fungi, bacteria, and yeasts, can act as antagonistic biocontrol agents where they secrete elicitors that prime defense reactions in fruits and vegetables. The use of physical, chemical, and biological inducers or elicitors to manage and control postharvest diseases is reviewed in this chapter, which briefly presents current knowledge about elicitors and mechanisms of induced resistance in fresh fruits and vegetables.read more

Reactive oxygen species-mediated the accumulation of suberin polyphenolics and lignin at wound sites on muskmelons elicited by benzo (1, 2, 3)-thiadiazole-7-carbothioic acid S-methyl ester
TL;DR: In this article, the BTH treatment also enhanced the activity of NADPH oxidase and superoxide dismutase, increasing the production of O2•- and H2O2.

TL;DR: In this paper, the results of a study indicated that BTH treatment maintained cell membrane integrity, increased PLA2 activity, and decreased phospholipase C (PLC) and D (PLD) activities in Penicillium expansum-inoculated apple fruit.

Soluble sugars, organic acids and energy metabolism involved in the wound healing of muskmelons elicited by benzothiadiazole
TL;DR: In this article , the authors investigated the effect of BTH dipping on the sugar, organic acids and energy metabolism of muskmelons during wound healing, and found that BTH increased fructose, glucose and sucrose contents at wounds of musmelons in the early stage of wound healing.
Journal ArticleDOI
BTH-induced joint regulation of wound healing at the wounds of apple fruit by JA and its downstream transcription factors.
TL;DR: Zhang et al. as mentioned in this paper showed that BTH treatment upregulated gene expression of MdLOX3.1, MdAOS1, MDAOC, and MDOPR3, promoting jasmonic acid synthesis at fruit wounds.

Ammonium secretion during Colletotrichum coccodes infection modulates salicylic and jasmonic acid pathways of ripe and unripe tomato fruit.
TL;DR: Green fruit and red fruit displayed similar gene expression patterns although only red fruit is susceptible to colonization, and it is likely that the resistance of green fruit to C. coccodes colonization is due to additional factors.
