“…Subsequently, the sections were deparaffinized in xylene (10 min) twice and in an ethanol series. The sections were air dried and observed under a fluorescence microscope (DM4000B LED, Leica Microsystems Co., Germany) using a fluorescence excitation filter at 470–495 nm and an emission filter at 510–550 nm . Melanin was observed under white light .…”

“…POD and PPO activities were assayed as described by Tao et al For POD assay, the reaction mixture contained 0.5 mL of crude enzyme, 1.5 mL of sodium phosphate buffer (100 mmol L −1 , pH 7.0) and 1.5 mL of guaiacol (25 mmol L −1 ). The increase in absorbance at 470 nm was recorded spectrophotometrically after addition of 20 μL H 2 O 2 .…”

“…In response to wounding, phenylalanine ammonia‐lyase (PAL), peroxidase (POD), and catalase (CAT) are stimulated and implicated in SPP formation in potato tubers, tomato fruits, muskmelon rind, and lettuce leaves . PAL catalyzes the first step in the phenylpropanoid pathway, producing trans ‐cinnamic acid and p ‐coumaric acid monomers which flow through a proposed route of biosynthesis forming precursors for assembly into SPP .…”

“…Complete healing requires a complexly structural and physiological progress starting with a rapid oxidation at the wound surface (Razem and Bernards 2003), and followed by the establishment of a functional suberin system (Dastmalchi et al 2015). In addition, the formation of wound-healing layer was reported to involve hormone signaling, as well (Cookson et al 2013;Tao et al 2016). The phytohormone abscisic acid (ABA) was associated to the wound-healing of potato tuber (Lulai et al 2008;Kumar et al 2010) and tomato fruit (Tao et al 2016).…”

Fruit wounding occurred at harvest and transportation requires rapid suberization as a major part of the healing process to prevent infection and desiccation. The focus of this work was to explore the mediation of abscisic acid (ABA) on woundinduced suberization and to determine expression profiles of specific genes involved in wound-induced suberization in tomato fruit. The measurements of weight loss and fruit firmness suggested wound-induced suberization started at 2 d after wounding. The suberization process with the accumulation of suberin polyphenolics (SPP) and polyaliphatics (SPA) observed through autofluorescence microscopy and Sudan IV staining was accelerated by ABA. Expressions of SlPAL5 and Sl4CL involved in the synthesis of SPP reached the highest at 4 and 8 d after wounding following ABA application, respectively. Associated with SPA biosynthesis, SlLACS1 and SlLACS2 showed the most abundant transcripts at 8 and 6 d in ABA group, respectively. Transcript levels including SlKCSs, SlCYP86B1, SlFAR3, and SlGPATs were up-regulated at 2 d after wounding by ABA. Activities of polyphenol oxidase and lipoxygenase were also enhanced during wound-induced suberization following ABA application. The results in this study proved that ABA accelerated the wound-induced suberization progress by increasing the transcript levels of relevant genes in postharvest tomato fruit.

Postharvest benzothiazole treatment enhances healing in mechanically damaged sweet potato by activating the phenylpropanoid metabolism

BACKGROUNDSweet potato often suffers mechanical damage during harvest, handling, and transportation. Infections, water loss, and quality changes of sweet potato caused by mechanical damage pose great financial losses. Wound healing is an effective method to alleviate such problems. In this study, the effects of postharvest treatment with benzothiazole (BTH) on wound healing of sweet potato was investigated.RESULTSPostharvest BTH treatment of sweet potatoes promoted lignin accumulation in wounded tissues, and 100 mg L−1 BTH exhibited better effects than 50 mg L−1 or 150 mg L−1 BTH. The biosynthesis of lignin in wounded tissues significantly decreased the weight loss of sweet potatoes. An increase in respiration intensity after BTH treatment was observed. The total phenolic and flavonoid contents and the activity of phenylalanine ammonia‐lyase, peroxidase, and polyphenol oxidase were increased in BTH‐treated sweet potatoes. This suggests that BTH increases phenylpropanoid metabolism.CONCLUSIONPostharvest 100 mg L−1 BTH treatment could promote wound healing in mechanically damaged sweet potatoes. The activation of the phenylpropanoid metabolism might be the mechanism of action of BTH in wound healing. © 2020 Society of Chemical Industry
