Novel applications of exogenous melatonin on cold stress mitigation in postharvest cucumbers

TL;DR: In this article , the authors found that exogenous application of melatonin modulates ROS homeostasis by regulating the antioxidant enzymes and nonenzymatic antioxidants systems, and that melatonin often interacts with hormones and other signaling molecules, such as ROS, nitric oxide (NO), hydrogen sulfide (H2S), and etc.

TL;DR: Melatonin treatment enhances bioactive compound retention, antioxidant activity and shelf‐life of bell pepper by delaying ripening and senescence.

TL;DR: This study explores phytomelatonin's role in plant stress tolerance, postharvest life, and marketability, highlighting its potential to improve fruit and vegetable quality through biosynthesis regulation, enzyme modification, and interaction with plant hormones and other regulators.

TL;DR: The findings suggest that the effectiveness of algal extracts in alleviating specific types of environmental stress is not solely dependent on the habitat from which the algae are derived.

TL;DR: It is shown that MT treatment can be an effective technique to reduce postharvest CI during low temperature storage of peach fruit and its effects on chilling injury and phenolic metabolism were studied.

TL;DR: In this review, the multiple roles of vitamin C in plant physiology as well as the regulation of its content, through biosynthetic or recycling pathways, are analyzed and attention is paid to the strategies that have been used to increase the content of vitamins C in crops.

TL;DR: It seems that the 2-hydroxymelatonin is a major metabolite of melatonin in plants and its level is roughly 400-fold higher than that ofMelatonin, and several new enzymes for melatonin metabolism in plants have been cloned and these enzymes are absent in the animals.

TL;DR: The results suggest that an optimal endogenous melatonin level is critical, not only for its self-antioxidant capacity, but also for maintaining an efficient enzymatic antioxidant system and redox homeostasis under perturbed environmental conditions.
