Abstract
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.
