“…Invasion by fungi also loosens the cells, and the degradation of pectin leads to the decomposition of cellulose and hemicellulose (Singh & Dwivedi, 2008). Studies also have shown that deterioration of plant cell walls leads to loss of cellular tissue structure, which causes a chain reaction of imbalances (Kaur et al, 2019).…”

“…On the one hand, ROS have antioxidant effects and protect plants from pathogens or are used as signaling molecules to control various biological processes (Berni et al, 2019;Qin et al, 2020;Tománková et al, 2006). On the other hand, once ROS accumulation exceeds a certain level, the protective mechanism collapses, leading to oxidative damage and internal decomposition of tissues (Kaur et al, 2019).…”

Munage grape (Vitis vinifera L. cv. Munage.) is a unique cultivar in southern Xinjiang, China. Spike stalk browning in this species has becomes more common in recent years, negatively impacting the shelf life, and causing severe economic losses during storage.This study investigated the changes in metabolisms of cell wall by Botrytis cinerea infection in association with spike stalk browning. Morphological and physiological observations showed that preharvest B. cinerea infection accelerates the spike stalk browning during storage in Munage grapes by promoting cell wall degradation. Accordingly, the cell structures in infected spike stalk showed severe collapse, while the cell structures in uninfected spike stalk remained relatively complete. Furthermore, the contents of CDTA-soluble pectin (CSP), Na 2 CO 3 -soluble pectin (NSP), cellulose, and hemicellulose were reduced, while the water-soluble pectin (WSP) content was increased during infection. In addition, the activities of polygalacturonase (PG), pectin methylesterase (PME), beta-galactosidase (β-Gal), and cellulase (Cx) were highly promoted by B. cinerea.Correspondingly, the expression levels of VvPG were markedly upregulated after inoculation and played a major role in cell wall degradation. Additionally, the spike stalk inoculated by B. cinerea showed higher activities of PPO and POD, and content of total phenolics. These results contribute to elucidating the relationship between cell wall degradation induced by B. cinerea during spike stalk browning and provide a basis for future research on improving the ability of the host cell wall to resist degrading enzymes. Practical applicationsBotrytis cinerea is the main fungal pathogen causing the gray mold of grapes. It usually enters the tissue early in crop development, has a long incubation period, and rapidly infects the tissue when the environment is favorable and the host physiology changes.Gray mold has been reported as one of the major postharvest diseases of grapes.However, there are relatively few reports on the pathways through which B. cinerea causes the browning of grape stalks. Controlling browning caused by B. cinerea may require clarification of the physiological and molecular mechanisms by which browning occurs. The elucidation of the role of B. cinerea in causing browning of grape stalks through the cell wall degradation pathway will help to provide scientific basis for further controlling browning, maintaining freshness of stalks, developing biological agents to prevent browning, improving grape quality, and extending storage period.

“…Rosales et al [41] observed that the application of a 3-day CO 2 treatment at 0 • C reduced the rachis browning index and sharply increased PPO gene expression in non-treated bunches. In this sense, the application of hexanal formulation to improve table grape quality suppressed PPO-related browning which maintained rachis freshness [74].…”

Table grape is a fruit with increasing interest due to its attributes and nutritional compounds. During recent years, new cultivars such as those without seeds and with new flavors have reached countries around the world. For this reason, postharvest treatments that retain fruit quality need to be improved. However, little is known to date about the biochemical and molecular mechanisms related with observed quality improvements. This review aims to examine existing literature on the different mechanisms. Special attention will be placed on molecular mechanisms which activate and regulate the different postharvest treatments applied in order to improve table grape quality.

Postharvest hexanal application delays senescence and maintains quality in persimmon fruit during low‐temperature storage

BACKGROUNDPersimmon (Diospyros kaki L.) fruit is characterized by rapid metabolic changes following ripening, and softening occurs due to the gradual breakdown of the cell membrane by direct catabolic cascades of phospholipase D enzyme on the phospholipid bilayer. Cell membrane weakening is also enhanced by the generation of reactive oxygen species during stress conditions such as cold storage and postharvest handling. This research evaluated the postharvest hexanal dipping application on persimmon fruit storage quality.RESULTSThe response of ‘MKÜ Harbiye’ persimmon fruit to exogenous hexanal at different concentrations (0.04% and 0.08%, named as HEX‐I and HEX‐II, respectively) on quality parameters, chilling injury (CI), microbial growth, antioxidant compounds and free radical scavenging capacity (FRSC) during storage at 0 °C and 80–90 ± 5% relative humidity for 120 days were evaluated. Both hexanal treatments retained quality and delayed senescence, as indicated by greener peel (lower a* and L* values), higher firmness, total phenol concentration, FRSC and titratable acidity, but lower weight loss, electrical conductivity, rate of CO2, ethylene production, decay and microbial growth than the control. Total soluble solids were lower in treated fruit than the control up to 100 days, and were much lower in HEX‐I treatment as compared to HEX‐II treatment. HEX‐I treatment exhibited lower CI than the other treatments during storage.CONCLUSIONHexanal at 0.04% could be used to increase the storage period of ‘MKÜ Harbiye’ persimmon fruit up to 120 days at 0 °C and 80–90 ± 5% relative humidity by retaining quality and delaying senescence. © 2023 Society of Chemical Industry.
