Special Issue Information

Dear Colleagues,

Fruits and vegetables represent a significant portion of the world's food waste. The overall quality of fruit and vegetable products results from various biochemical processes that occur beforehand. Therefore, it is essential for scientists to study them. Understanding the profile, roles, biochemistry and/or regulation of metabolites is crucial in modulating, improving and extending their post-harvest shelf-life while also increasing knowledge about specific physiological and biochemical metabolism.

Thus, the purpose of this Special Issue is to collect research and review articles focused on recent advancements in the main metabolic changes that occur during both the pre- and post-harvest stages of fruit and vegetables. The inclusion of applications involving pre- or post-harvest strategies, such us bio-stimulants or abiotic stresses (not exclusively), with the ultimate aim of prolonging postharvest life, reducing the incidence of pathogens or deterioration reactions, and enhancing or preserving valuable metabolites contributing to nutritional and sensorial quality is encouraged. This Special Issue will also cover advances in understanding the mechanisms of chilling injury and technologies to mitigate or delay its occurrence. Contributions related to recent biochemical aspects, changes and/or the regulation of metabolites and enzymes associated with microorganism incidence and product ripening/senescence are welcome. Finally, methodology development for detecting metabolites or changes in metabolic pathways are also welcome.

Global plant production is challenged by unpredictable (a)biotic stresses that occur individually, simultaneously or staggered. Due to an increasing demand for environmentally friendly plant production, new sustainable, universal, and preventive measures in crop protection are needed. We postulate thermopriming as a suitable procedure that fulfills these requirements. Therefore, we performed thermopriming as a pre-conditioning on tomato transplants in combination with two subsequent salt stress treatments to evaluate their single and combined physiological effects on leaves and fruits with regard to plant performance, fruit yield and quality. We identified a cross-tolerance to salinity that was triggered by the preceding thermopriming treatment and resulted in an accumulation of phenols and flavonols in the leaves. Plant growth and fruit yield were initially delayed after the stress treatments but recovered later. In regard to fruit quality, we found an increase in carotenoid and starch contents in fruits due to thermopriming, while sugars and titratable acidity were not affected. Our results indicate that thermopriming can mitigate the impact of subsequent and recurrent stress events on plant performance and yield under production-like conditions. Full article
