“…Hence, it is presumed that the interference expression of StMSD may suppress phenylpropanoid metabolism by reducing H 2 O 2 production. Although phenolic acids and lignin monomers, as the metabolites of phenylpropanoid metabolism, contribute to the formation of SPP and lignin at tuber wounds, there are still some phenolic acids and flavonoids that participate in scavenging of the free radical, which keeps the ROS homeostasis of wounds during healing [ 32 ].…”

Superoxide dismutase (SOD) actively participates in the wound stress of plants. However, whether StMSD mediates the generation of H2O2 and the deposition of suberin polyphenolic and lignin at potato tuber wounds is elusive. In this study, we developed the StMSD interference expression of potato plants and tubers by Agrobacterium tumefaciens-mediated transformation. The StSOD expression showed a marked downregulation in StMSD-interference tubers, especially StCSD2 and StCSD3. The content of O2•− exhibited a noticeable increase together with the inhibition in H2O2 accumulation. Moreover, the gene expression levels of StPAL (phenylalanine ammonia-lyase) and StC4H (cinnamate-4-hydroxylase) were downregulated in StMSD-interference tubers, and less suberin polyphenolic and lignin depositions at the wounds were observed. Taken together, the interference expression of StMSD can result in less suberin polyphenolic and lignin deposition by inhibiting the disproportionation of O2•− to H2O2 and restraining phenylpropanoid metabolism in tubers.

“…Furthermore, application of chito-oligosaccharide, a chitosan degradation product, to injured potatoes accelerated wound healing and reduced postharvest losses [67]. Chitooligosaccharide-induced ROS metabolism, increased gene expression and activities of CAT, POD and enzymes responsible for the synthesis of ascorbic acid and glutathione.…”

Fresh-cut potatoes (FCP), like other fresh-cut (minimally processed) vegetables, are a convenient but highly perishable product. Unlike most fresh-cut vegetables, which are “ready-to-eat”, FCP must be cooked before consumption. Therefore, in addition to the safety (chemical and microbiological), quality and sensory characteristics of raw FCP, the same requirements should be applied for cooked potatoes. It is known that many factors play a role in meeting all these requirements: (i) selection of cultivars less susceptible to browning; (ii) use of anti-browning and antimicrobial agents and/or certain physical methods against browning and microbial growth; (iii) packaging and cold storage conditions. In recent studies on FCP, scientists have attempted to deepen their knowledge of the mechanisms of browning prevention to better understand changes at the molecular level as well. The main objective of this review is to provide a comprehensive overview of recent research, which aimed at deepening knowledge of the various changes that occur in potatoes during processing, and to develop new approaches that could help improve quality and extend FCP shelf life. It also discusses the effects of subsequent cooking of FCP on sensory and other properties, as well as on chemical constituents.
