Abstract
- Postharvest harmful pathogenic infestation leads to rapid decay in longan fruit. Compared with P. longanae -infected longans, AEOW alleviated fruit disease severity and diminished the O 2 -. production rate and MDA content. It also increased APX, CAT, and SOD activities, delayed the decrease in the levels of GSH and AsA, as well as the reducing power and DPPH radical scavenging ability, which resulted in a decline in membrane lipid peroxidation in P. longanae -infected longans. Additionally, AEOW reduced LOX, lipase, PI-PLC, PC-PLC, and PLD activities, maintained higher levels of PC, PI, IUFA, USFAs, and U/S, while reducing levels of PA, DAG, SFAs, and CMP. These effects alleviated membrane lipid degradation and peroxidation in P. longanae -infected longans. Consequently, AEOW effectively maintained membrane integrity via improving antioxidant capacity and suppressing membrane lipid peroxidation. This comprehensive coordination of ROS and membrane lipid metabolisms improved fruit resistance and delayed disease development in longans. • AEOW reduced O 2 -. burst, MDA production, and CMP rise in P. longanae -infected longan. • AEOW treatment enhanced the antioxidation capacity of P. longanae -infected longan. • AEOW treatment lowered the membrane lipid peroxidation of P. longanae -infected longan. • AEOW reduced P. longanae -induced fruit disease through enhancing antioxidant system. • AEOW reduced P. longanae -induced fruit disease by maintaining cell membrane integrity.
