Manipulation of cellular energy reveals the relationship between ultraweak luminescence and cellular energy during senescence of strawberry (Fragaria × ananassa) fruits

Dicyclohexylcarbodiimide and disodium succinate induce the change of energy metabolism in relation to longan pulp breakdown

“…The relationship between energy levels and quality decline in postharvest produce has been demonstrated through experiments with ATP treatment, confirming that a high energy level in fresh produce could maintain structural integrity and function of mitochondria, thus effectively delaying spoilage in pears ( Duan et al, 2019 ), mung beans ( Chen et al, 2019 ), and strawberries ( Li et al, 2021 ). However, energy depletion, induced by 2,4-dinitrophenol treatment, could reduce stress resistance, and exacerbate physiological disorders in strawberries and apples ( Guo, Liu, Bai, Yan, & Li, 2018 ; Shu, Cao, & Jiang, 2022 ).…”

ε-Poly-l-Lysine Enhances Fruit Disease Resistance in Postharvest Longans (Dimocarpus longan Lour.) by Modulating Energy Status and ATPase Activity

“…However, NO + M. fructicola remained a higher level of Ca 2+ -ATPase activity, significantly reducing the incidence and severity of peach fruit disease [ 9 ]. In addition, Guo et al (2018) showed that the activities of H + - and Ca 2+ -ATPase, and the content of ATP gradually dropped along with the senescence of strawberry fruits [ 13 ]. DNP was an uncoupling agent of the respiratory chain that inhibits ATP production.…”

“…Nevertheless, ATP treatment reduced the decrease in H + - and Ca 2+ -ATPase activities, and energy charge. The ATP-treated samples had the lowest decay rate [ 13 ]. Chen et al (2018) demonstrated that P. longanae infection exacerbated the disease development in harvested longan fruit.…”

“…The level of ATPase activity can reflect the cell membranes integrity, which affects fruit disease resistance [ 8 , 12 ]. A previous study about strawberry fruit indicated that 2,4-dinitrophenol (DNP) could promote fruit disease development via decreasing energy charge and ATP content, keeping lower activities of H + -ATPase and Ca 2+ -ATPase, and finally destroying mitochondrial function, while the addition of ATP could slow this process [ 13 ]. Similar results were reported by Li et al (2020) who indicated that benzothiadiazole treatment could greatly reduce the lesion diameter of Penicillium expansum -inoculated apple fruit and enhance H + - and Ca 2+ -ATPase activities, which was coincided with the raised ATP level and energy status [ 14 ].…”
