“…Lignin levels in seedlings can be quantified by A 280 in UV spectrophotometry [ 30 ]. These results indicated that high dose LGC up-regulated phenylalanine metabolism and the phenylpropanoid pathway and increased lignin expression levels, which would solidify the cell wall and inhibit root growth [ 31 ]. On the contrary, a low concentration of LGC down-regulated the metabolism of phenylalanine and the synthesis pathway of precursors of lignans, phenylpropanoid, which would inhibit the expression level of lignans and promote plant growth.…”

Laxogenin C (LGC) is a natural spirostanol deriving from plant hormone which has shown growing regulation similar to those of brassinosteroids. In the present study, LGC showed a promoting effect on tomato seed germination and seedling growth in a dose-dependent manner. We applied LC-MS/MS to investigate metabolome variations in the tomato treated with LGC, which revealed 10 differential metabolites (DMs) related to KEGG metabolites, associated with low and high doses of LGC. Enrichment and pathway mapping based on the KEGG database indicated that LGC regulated expressions of 2-hydroxycinnamic acid and l-phenylalanine to interfere with phenylalanine metabolism and phenylpropanoids biosynthesis. The two pathways are closely related to plant growth and lignin formation. In our further phenotypic verification, LGC was confirmed to affect seedling lignification and related phenylpropanoids, trans-ferulic acid and l-phenylalanine levels. These findings provided a metabolomic aspect on the plant hormone derivates and revealed the affected metabolites. Elucidating their regulation mechanisms can contribute to the development of sustainable agriculture. Further studies on agrichemical development would provide eco-friendly and efficient regulators for plant growth control and quality improvement.

“…Among the different studies, washing times vary from 30 s to 24 h depending on the tested compounds. Boonsiriwit et al . noted that melatonin treatment (100 μM) for 30 min effectively maintained green asparagus postharvest quality (i.e., color, texture) during cold storage (4 °C) for 25 days by delaying chlorophyll degradation and reducing lignin content.…”

Melatonin delayed lignin increase by decreasing PAL and POD activities, while it delayed asparagus senescence and chlorophyll degradation by enhancing the activities of the antioxidant enzymes CAT and SOD, that react and deactivate ROS.…”

Sustainable Postharvest Treatments for Prolonging Asparagus (Asparagus officinalis L.) Shelf Life by Minimizing the Development of Physiological Disorders

Asparagus (Asparagus officinalis L.) is a non-climacteric vegetable, well-known for its nutritional properties. Asparagus is consumed either fresh, frozen, or processed into canned food. Fresh asparagus has a short shelf life due to its high respiration rates, which results in asparagus quality loss. Asparagus quality loss is also associated with the development of physiological disorders (i.e., stem discoloration, bract opening, and toughening) during postharvest storage. The current study reviews various sustainable postharvest treatments that can be applied to minimize asparagus postharvest losses by controlling the development of physiological disorders. The mechanisms of action of sustainable treatments and the mechanisms involved in physiological disorder development are comprehensively discussed. Packaging, edible coatings, washing with environmentally and human-friendly compounds, storage in a controlled atmosphere, heat treatment, ultrasound treatment, and electrostatic atomized water particle treatments can successfully maintain asparagus quality. Multidisciplinary studies are encouraged to investigate the mechanism of action of sustainable treatments.

“…Melatonin treatment could increase pomegranate fruit quality, especially the aril color and antioxidant components at harvest and storage periods ( Lorente-Mento et al, 2021 ). The compound also improved the postharvest quality of green asparagus ( Boonsiriwit et al, 2021 ) and mushroom ( Lin et al, 2022 ).…”

Postharvest quality of litchi reduces rapidly during storage at room temperature. This study aimed to investigate the effect of melatonin treatment on postharvest quality and oxidative stress markers of litchi fruit during cold storage. The “Feizixiao” litchi was treated with melatonin solution concentrations of 0.2 and 0.6 mmol·L−1 and then stored at 4°C for 12 days. The results confirmed that the melatonin treatment effectively maintained the appearance and color of the litchi fruit, suppressed the peel browning, and improved the litchi quality. The treatment also significantly enhanced the levels of endogenous melatonin, antioxidant components (total phenolics, flavonoids, and anthocyanin), and antioxidant enzyme activities of the fruit. It also inhibited the other oxidative stress markers, such as O2−, H2O2, MDA, and protein carbonyl content, and upregulated the expressions of antioxidant and Msr-related genes. Correlation and principal component analyses further confirmed that the melatonin treatment effectively delayed the fruit senescence by enhancing the antioxidant enzyme activities and modulating peel browning and reactive oxygen species metabolism of the litchi fruit via regulating gene expression of the related enzymes (SOD and PPO). These findings suggested that the exogenous application of melatonin to litchi during the postharvest is an ideal way to preserve the fruit quality and delay fruit senescence.
