Abstract
Rapid wound healing is crucial in protecting sweet potatoes (Ipomoea batatas ) against infection, water loss and quality deterioration during storage. The current study investigated how acibenzolar-S-methyl (ASM) treatment influenced wound healing in harvested sweet potatoes by investigating the underlying mechanism. It was found that ASM treatment of wounded sweet potatoes induced a significant accumulation of lignin at the wound sites, which effectively suppressed weight loss. After 4days of healing, the lignin content of ASM-treated sweet potatoes was 41.8% higher than that of untreated ones, and the weight loss rate was 20.4% lower. Moreover, ASM treatment increased the ability of sweet potatoes to defend against wounding stress through enhancing processes such as increased production of reactive oxygen species (ROS), activation of enzymes involved in the ROS metabolism (peroxidase, superoxide dismutase and catalase) and phenylpropanoid pathway (phenylalanine ammonia lyase, cinnamate-4-hydroxylase, 4-coumarate-CoA ligase and cinnamyl alcohol dehydrogenase), and intensive synthesis of phenolics and flavonoids. These results suggest that treating harvested sweet potatoes with ASM promotes wound healing through the activation of the ROS metabolism and phenylpropanoid pathway.

Abstract
Postharvest physiological deterioration (PPD) reduces the availability and economic value of fresh produces, resulting in the waste of agricultural products and becoming a worldwide problem. Therefore, many studies have been carried out at the anatomical structural, physiological and biochemical levels and molecular levels of PPD of fresh produces to seek ways to manage the postharvest quality of fresh produce. The cell wall is the outermost structure of a plant cell and as such represents the first barrier to prevent external microorganisms and other injuries. Many studies on postharvest quality of crop storage organs relate to changes in plant cell wall-related components. Indeed, these studies evidence the non-negligible role of the plant cell wall in postharvest storage ability. However, the relationship between cell wall metabolism and postharvest deterioration of fresh produces has not been well summarized. In this review, we summarize the structural changes of cell walls in different types of PPD, metabolic changes, and the possible molecular mechanism regulating cell wall metabolism in PPD of fresh produce. This review provides a basis for further research on delaying the occurrence of PPD of fresh produce.

Chitooligosaccharide accelerated wound healing in potato tubers by promoting the deposition of suberin polyphenols and lignin at wounds. PLANT PHYSIOLOGY AND BIOCHEMISTRY : PPB 2023; 199:107714. [PMID: 37119550 DOI: 10.1016/j.plaphy.2023.107714] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/02/2022] [Revised: 04/08/2023] [Accepted: 04/18/2023] [Indexed: 05/01/2023]
Abstract
Chitooligosaccharide (COS) is a low molecular weight product of chitosan degradation. Although COS induces plant resistance by activating phenylpropanoid metabolism, there are few reports on whether COS accelerates wound healing in potato tubers by promoting the deposition of phenolic acids and lignin monomers at wounds. The results showed that COS activated phenylalanine ammonialyase and cinnamate 4-hydroxylase and promoted the synthesis of cinnamic, caffeic, p-coumaric, ferulic acids, total phenolics and flavonoids. COS activated 4-coumaric acid coenzyme A ligase and cinnamyl alcohol dehydrogenase and promoted the synthesis of sinapyl, coniferyl and cinnamyl alcohols. COS also increased H2O2 levels and peroxidase activity and accelerated the deposition of suberin polyphenols and lignin on wounds. In addition, COS reduced weight loss and inhibited lesion expansion in tubers inoculated with Fusarium sulfureum. Taken together, COS accelerated wound healing in potato tubers by inducing phenylpropanoid metabolism and accelerating the deposition of suberin polyphenols and lignin at wounds.

Abstract
Starch degradation occurs rapidly in stressed plants, but it is unclear how starch degradation occurs in potato tubers after they incur mechanical wounding. In this study, we found that wounding significantly upregulated the expression levels of StGWD, StAMY, StBAM, and StISA, and decreased the starch content of potato tubers. Meanwhile, wounding markedly upregulated the expression levels of StSUS, StBG, and StINV genes, and increased the content of sucrose, glucose, and fructose. Furthermore, wounding reduced the proportion of small starch granules and increase that of large as well as medium starch granules, in this way enhancing the average size distribution of starch. Initially, the hard surface layer of starch granules was removed by wounding, but the internal channels and other structures were only slightly affected. Taken together, the results show that wounding can accelerate starch degradation by promoting the accumulation of sucrose, glucose, and fructose, and the hydrolysis of starch granules in potato tubers.

Interference Expression of StMSD Inhibited the Deposition of Suberin and Lignin at Wounds of Potato Tubers by Reducing the Production of H2O2. Antioxidants (Basel) 2022; 11:antiox11101901. [PMID: 36290624 PMCID: PMC9598499 DOI: 10.3390/antiox11101901] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/09/2022] [Revised: 09/20/2022] [Accepted: 09/20/2022] [Indexed: 11/17/2022] Open
Abstract
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.

Chitooligosaccharide Maintained Cell Membrane Integrity by Regulating Reactive Oxygen Species Homeostasis at Wounds of Potato Tubers during Healing. Antioxidants (Basel) 2022; 11:antiox11091791.

Abstract
Chitooligosaccharide (COS) is a degradation product of chitosan. Although COS increased fruit resistance by regulating the metabolism of reactive oxygen species (ROS), few reports are available on whether COS regulates ROS homeostasis at wounds of potato tubers during healing. In this study, COS increased gene expression and activities of NADPH oxidase and superoxide dismutase, and promoted the generation of O2●- and H2O2. Moreover, COS increased gene expression and activities of catalase, peroxidase, and AsA-GSH cycle-related enzymes, as well as the levels of ascorbic acid and glutathione levels. In addition, COS elevated the scavenging ability of DPPH, ABTS+, and FRAP, and reduced cell membrane permeability and malondialdehyde content. Taken together, COS could maintain cell membrane integrity by eliminating excessive H2O2 and improving the antioxidant capacity in vitro, which contributes to the maintainance of cell membrane integrity at wounds of potato tubers during healing.

PLANT PHYSIOLOGY AND BIOCHEMISTRY : PPB 2022; 185:279-289. [PMID: 35724622 DOI: 10.1016/j.plaphy.2022.06.010] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/11/2022] [Revised: 05/21/2022] [Accepted: 06/10/2022] [Indexed: 06/15/2023]
Abstract
Calcium-dependent protein kinase (CDPK) is a Ca2+ sensor that can phosphorylate and regulate respiratory burst oxidase homolog (Rboh), inducing the production of O2-. However, little is known about how StCDPK23 affects ROS production in the deposition of suberin at potato tuber wounds by regulating StRbohs. In this study, we found that StCDPK23 was induced significantly by the wound in potato tubers, which contains a typical CDPK structure, and was highly homologous to AtCDPK13 in Arabidopsis. Subcellular localization of results showed that StCDPK23 was located in the nucleus and plasma membrane of N. benthamiana epidermis cells. StCDPK23-overexpressing plants and tubers were obtained via Agrobacterium transformation. The expression of StCDPK23 was significantly upregulated in the overexpressing tubers during healing and increased 2.3-fold at 5 d. The expression levels of StRbohs (A-E) were also upregulated in the overexpressing tubers. Among them, StrbohA showed significant expression in the early stage of healing, which was 16.3-fold higher than that of the wild-type tubers at 8 h of healing. Moreover, the overexpressing tubers produced more O2- and H2O2, which are 1.1-fold and 3.5-fold higher than that of the wild-type at 8 h, respectively. More SPP deposition was observed at the wounds of the overexpressing tubers. The thickness of SPP cell layers was 53.2% higher than that of the wild-type after 3 d of the wound. It is suggested that StCDPK23 may participate in the wound healing of potato tubers by regulating Strbohs, which mainly contributes to H2O2 production during healing.
