摘要

低温贮藏可延长水果的货架期，但在低于可容忍水平的温度下长期贮藏可能会对敏感商品造成采后冷害（PCI）。本综述旨在强调水果中三磷酸腺苷（ATP）的活化以及细胞外 ATP（eATP）和细胞内 ATP（iATP）的相互作用，并找出其在减轻果实冷害中的重要作用。对各种途径，如恩伯登-梅耶霍夫-帕尔纳斯途径、三羧酸循环、磷酸戊糖途径、γ-氨基丁酸分流途径和细胞色素途径进行了深入研究，以阐明它们在持续供应 ATP 和保持膜流动性和完整性方面的作用。本综述总结了有助于调节水果能量代谢的处理方法。此外，这项工作还深入探讨了能量状态在减弱耐寒性方面的作用。此外，它还指出了烟酰胺腺嘌呤二核苷酸在减轻 PCI 方面的潜力。此外，它还讨论了 eATP 及其受体 DORN1 在减轻寒冷胁迫中的作用。

Is ATP a Signaling Regulator for Postharvest Chilling Tolerance in Fruits?

Low-temperature storage is used to extend the shelf life of fruits, but prolonged storage at temperatures below tolerable levels may cause postharvest chilling injury (PCI) in sensitive commodities. This review aims to highlight adenosine triphosphate (ATP) activation and the interplay of extracellular ATP (eATP) and intracellular ATP (iATP) in fruits and to find out its significance in mitigating PCI. Various pathways, such as the Embden-Meyerhof-Parnas pathway, the tricarboxylic acid cycle, the pentose phosphate pathway, the γ-aminobutyric acid shunt pathway, and the cytochrome pathway, are studied critically to elucidate their role in continuous ATP supply and maintaining the membrane fluidity and integrity. This review summarizes the treatments helpful in modulating energy metabolism in fruit. Additionally, this work provides insights into the energy status in attenuating chilling tolerance. Moreover, it states the potential of nicotinamide adenine dinucleotide in mitigating PCI. Furthermore, it discusses the role of eATP and its receptor DORN1 in mitigating chilling stress.
