Special Issue Information

Dear Colleagues,

Fruits face a range of abiotic stresses during production, postharvest handling, storage and distribution. Abiotic stress such as salinity, drought, extreme temperatures, nutrient deficiencies and exposure to heavy metals can significantly reduce both fruit productivity and quality. Enhancing the ability of fruits to tolerate these stresses is crucial for maintaining high yields in challenging conditions. In this regard, fruits have evolved various adaptive mechanisms at the physiological, biochemical and molecular levels to mitigate the impact of these stresses.

A deeper understanding of how these mechanisms function and interact is essential for developing strategies to improve stress-tolerant fruit crops. Recent research advances have provided valuable insights into the complex processes that allow fruits to survive under adverse conditions. This includes the identification of stress-responsive genes, proteins and metabolites, as well as the role of signaling pathways in stress adaptation.

This Special Issue will explore both fundamental and applied aspects of stress tolerance, covering topics such as physiological responses, enzymatic activity, gene expression, functional genomics, molecular networks and innovative approaches to enhancing abiotic stress tolerance in fruits. All original research papers and reviews are welcome for submission to this Special Issue.

Persian lime is one of the most important citrus fruits in Mexico. This species suffers from a physiopathy called Wood Pocket (WP), which is characterized by chlorosis in leaves and fruits, necrosis in the trunk, and the eventual death of the tree. The actual scientific knowledge about WP is very little; however, the producers, researchers, and technicians associate it with abiotic stress. In the present study, we observed that Persian limes exposed to temperatures over 45 °C for five months developed WP symptoms, while those kept at 25 °C during the same time did not. Both groups were then physiologically characterized. Our results show that WP strongly affects most fluorescence and gas exchange parameters. Specially, we observe that stomatal fluxes were negative in WP leaves. Our results suggest that WP in Persian lime plants might be a physiological affectation caused by the prolonged exposure to high temperatures. It might be possible that the physiological affectation (gas exchange and water use efficiency) could be associated with a high-temperature-induced abscisic acid accumulation, which, in turn, might have caused stomatal closure in WP-affected plants. However, this hypothesis must be corroborated experimentally. Full article
