Effect of benzothiadiazole treatment on quality and anthocyanin biosynthesis in plum fruit during storage at ambient temperature

Abstract

BACKGROUND: Plums tend to experience a reduction in fruit quality due to ripening and they deteriorate quickly during storage at room temperature. Benzothiadiazole (BTH) is a plant elicitor capable of inducing disease resistance in many crops. In this study, the effect of BTH treatment on fruit ripening, fruit quality, and anthocyanin biosynthesis in 'Taoxingli' plum was investigated. RESULTS:The results showed that BTH treatment could accelerate fruit ripening without affecting the incidence of fruit decay or the shelf life. Benzothiadiazole treatment improved the quality and consumer acceptability of 'Taoxingli' plums during storage by increasing the sweetness, red color formation, and the concentration of healthy antioxidant compounds. The BTH treatment could also effectively promote the biosynthesis of anthocyanin by enhancing the enzyme activities of phenylalanine ammonia-lyase (PAL), dihydroflavonol 4-reductase (DFR), anthocyanidin synthase (ANS), and uridine diphosphate flavonoid 3-O-glucosyltransferase (UFGT) and up-regulating the gene expressions of PsPAL, PsCHI, PsDFR, PsANS, and PsUFGT during storage.CONCLUSION: Benzothiadiazole treatment could be a potential postharvest technology for improving fruit quality and consumer acceptability in harvested plum fruit.

Melatonin treatment maintains the quality of cherry tomato by regulating endogenous melatonin and ascorbate‐glutathione cycle during room temperature

“…The relative expressions of four genes relevant to endogenous MLT synthesis were assayed using real‐time quantitative PCR based on Huan et al (2020) previous method. Primer Premier 5 software was used to design primers (Table 1) for the tested genes.…”

Acibenzolar‐S‐methyl activates phenylpropanoid pathway to enhance resistance against Alternaria alternata in pear fruit

“…reported that ASM treatment enhanced disease resistance by increasing PAL, C4H and 4CL activities and gene expression, and promoting the content of secondary metabolites. Studies in pitaya, 15 blueberry, 6 strawberry, 37 muskmelon 13 and plum fruit 38 have indicated that postharvest application of ASM could increase anthocyanin and flavonoid content by enhancing PAL, 4CL and C4H activities. ASM treatment also induced disease tolerance in litchi, 10 peach, 18 mango, 31 banana, 32 Yali pear 30 and muskmelon 8 fruit by activating PAL activity as well as phenylalanine and flavonoid accumulation.…”

Identification of microRNAs and their target genes related to the accumulation of anthocyanin in purple potato tubers (Solanum tuberosum)

“…The anthocyanins were extracted from purple potato tubers using a modification of the method described by Huan et al ( 2020 ). One‐gram samples of fresh purple potato tubers were collected in triplicate at each stage (Sa–Sf).…”
