“…Phosphorylation and dephosphorylation could be the central links between the production of phytochemicals and multiple signaling molecules and transduction (Figure A), considering the decisive role of phosphorylation–dephosphorylation processes in regulating protein activities and biochemical processes. , Phosphorylation–dephosphorylation processes generally occur in plasma membrane proteins, as a downstream physiological process of plant receptors activation . For example, brassinosteroids (BR) signaling ubiquitously exists in environmentally stressed plants by regulating physiological processes to alleviate the deleterious effects induced by cold, heat, drought, etc.…”

Emerging evidence has confirmed the role of emerging nonthermal stressors (e.g., electromagnetic fields, ultrasonication, plasma) in accumulating bioactive metabolites in plant-based food. However, the signal decoding mechanisms behind NonTt-driven phytochemical production remain unclear, hindering postharvest bioactive component intensification. This study aims to summarize the association between signaling molecules and bioactive secondary metabolite production under nonthermal conditions, demonstrating the feasibility of enhancing phytochemical accumulation through signaling molecule crosstalk manipulation. Nonthermal elicitors were found to be capable of inducing stress metabolisms and activating various signaling molecules, similar to conventional abiotic stress. A simplified pathway model for nonthermally induced γ-aminobutyric acid accumulation was proposed with reactive oxygen species and calcium signaling being versatile pathways responsive to nonthermal elicitors. Manipulating signal molecules/pathways under nonthermal conditions can intensify phytochemical biosynthesis. Further research is needed to integrate signaling molecule responses and metabolic network shifts in nonthermally stressed plant-based matrices, balancing quality modifications and intensification of food functionality potential.

“…However, their method of action is not well known, limiting their use as useful products [10]. Elicitor compounds function as indicator molecules, whose detection at the cell-surface as well as consequent transmission activates plant defence genes [11]. As a result, innumerable defense complexes are synthesised, particularly structural proteins that support cell wall and also several enzymes intricate in the inhibition of invading mechanisms opted by the pests, through intricate activation of plant defense pathways (salicylic acid (SA), jasmonic acid (JA), and ethylene [12].…”

Background Seaweeds contain a widespread range of fatty acids (FA), and several of them have potential bioactivity. FAs are dynamic members of all biota, as well as being acknowledged for their critical function in initiating phytohormone interactions and acting as important participants in many defence signalling pathways of the plant system. The current study looks at the defense-eliciting potentials of fatty acids from the green seaweed Chaetomorpha antennina and their impact on the polyphagous insect pest Spodoptera litura (Fab). Results The seaweed was detected with 19 fatty acids, with larger proportion of hexa and octadecanoic and linoleic acids. The algal fatty acid compounds (CFA) was successful in eliciting salicylic acid and phenolic compounds biosynthesis along with enzymes peroxidase (PO) and polyphenol oxidase (PPO). The defense enzymes and phenol levels increased post infestation with S. litura. CFA was also effective in causing direct mortalities to the larvae (II-V instars). S. litura larvae exposed to elicited tomato plants were severely affected physiologically and morphologically, displaying visible aberrations as well as morphogenetic defects such as altered larval-pupal duration and biomass. Reproductive performances of adults were also severely affected. Decrease in food utilization, nutritional indices with a corresponding decrease in phosphatase and gut enzymes affirm feeding deterrence of the larvae, which was endorsed by histological analysis of midgut cell disruption of exposed larvae. Detoxification enzyme levels of exposed larvae denote the inability of larval immune system to evade harmfulness of CFA. Conclusion Hence, the study finally confirms the elicitor potentials of fatty acid compounds from C. antennina, by inducing natural systemic defences. This investigation unlocks novel forecasts besides delivering an unconventional method for crop protection to moderate or interchange the solicitation of chemical pesticides.

“…Cold storage (refrigeration) is used to extend the shelf life of fruits and vegetables. The following temperatures are recommended for storage: for tomatoes (8–10 °C and 13–21 °C for firm green and ripe green tomatoes, respectively), and for eggplants (8–12 °C) (Costa et al, 2022). However, cold storage alone is not effective in extending the shelf life of fruits and vegetables in most cases, and cold storage of fruits and vegetables with postharvest treatments is another important strategy for doing so.…”

The effects of postharvest applications of hot water (HWT) (45, 50, and 55°C), 1-MCP (1, 5, and 10 μL L−1), and CaCl2 (1, 2, and 3%) on polygalacturonase (PG), pectin methylesterase (PME), α-galactosidase ( α-Gal), β-galactosidase ( β-Gal) and β-1,4-glucanase ( β-1,4-Glu) activities, and the fruit firmness and cell wall composition of eggplant fruit were investigated. The results showed that the decrease in the eggplants firmness was delayed by HWT, 1-MCP, and CaCl2 treatments during storage compared with the control. However, HWTs were less effective than the 1-MCP and CaCl2 treatments. The results show that 1-MCP and CaCl2 treatments inhibited the depolymerization of water (WSP), CDTA (CSP), and sodium carbonate (SSP) soluble polyuronides. The results suggest that 1-MCP (5 and 10 μL L−1) and CaCl2 (1, 2, and 3%) could prevent eggplant softening by inhibiting hydrolase enzymes and reducing the disintegration of the polysaccharides. In addition, 1-MCP and CaCl2 were more effective than hot water treatment in extending postharvest storage life. There is a significantly high correlation between firmness, polyuronide content and cell wall enzyme activity.
