Fruits and vegetables are important components of the daily diet for good health. These a powerhouse essential vitamins, minerals, fibres antioxidants, making them protective food that builds immunity in human body. It is more relevant now since recent COVID-19 pandemic compromised immune system large section affected population. The perishability these products after harvest primary concern, particularly tropical subtropical agro-climatic regions worldwide. living nature harvested horticultural produce makes it challenging their quality assurance during subsequent distribution marketing. Numerous pre- post-harvest management techniques can increase shelf life horticulture produce. However, treatments concerning safety issues such as PHI (postharvest interval consumption pesticide application) MRL (Minimum Residue Level) chemicals foremost concern. In new artificial intelligence arena, sensors, molecules, intelligent packaging play vital role postharvest perishable crops. This paper highlights some critical using technologies

This study investigated the effect of melatonin (MT) on postharvest storage quality passion fruit. Passion fruits were treated with four different concentrations MT solutions (100, 200, 300 and 400 μmol/L) for 30 min stored 8 days. Compared control, optimal concentration (200 treatment significantly reduced shrinkage index, browning weight loss, ethylene production, respiration rate, delayed decline firmness, total soluble solids (TSS), color, thus maintaining fruits. Exogenous enhances antioxidant activity reduces fruit oxidative damage by inhibiting increase in pericarp cell membrane permeability, malondialdehyde (MDA) content, high ascorbic acid (AsA), phenolics, flavonoids increasing superoxide dismutase (SOD), catalase (CAT), peroxidase (POD), polyphenol oxidase (PPO) activities. These findings suggest that exogenous application is effective delaying senescence.

Lowering the storage temperature is an effective method to extend postharvest and shelf life of fruits. Nevertheless, this technique often leads physiological disorders, commonly known as chilling injuries. Apples pears are susceptible injuries, among which superficial scald most economically relevant. Superficial due necrotic lesions first layers hypodermis manifested through skin browning. In peaches nectarines, injuries characterized by internal symptoms, such mealiness. Fruits with these aesthetic or compositional/structural defects not suitable for fresh consumption. Genetic variation a key factor in determining fruit susceptibility injuries; however, physiological, technical aspects harvest maturity conditions also play role. Multi-omics approaches have been used provide integrated explanation injury development. Metabolomics pome fruits specifically targets identification ethylene, phenols, lipids, oxidation products. Genomics transcriptomics revealed interesting connections metabolomic datasets, pinpointing specific genes linked cold stress, wax synthesis, farnesene metabolism, metabolic pathways ascorbate glutathione. When applied Prunus species, cutting-edge uncovered that development mealiness symptoms ethylene signaling, cell wall lipid stress genes, increased DNA methylation levels. Emphasizing findings from multi-omics studies, review reports how integration omics datasets can new insights into understanding This information essential successfully creating more resilient varieties developing novel strategies.

Fresh-cut fruit and vegetables are susceptible to browning during storage subsequent consumption. The cell membrane acts as a vital structural barrier, compartmentalizing various substances within living organisms. fresh-cutting process induces mechanical injuries, disrupting these membranes resulting in the leakage of cellular contents. This facilitates direct contact between enzymes that mediate reactions. mini review explores potential roles fresh-cut from multi-omics perspective, aiming provide novel insights into underlying mechanisms vegetables. Considering blocking vegetables, future studies should focus on elucidating precise by which regulate reactions, directions for development more effective intervention strategies.

Water deficit severely limits plant growth especially in arid and semi-arid regions. Sunflower is one of the economically important oil producing crops. It usually grown water limited environment due to its moderate biological tolerance towards stress. Interestingly,sunflower was improved conditions using a promoter i.e. melatonin. Seeds were primed for 12 hours with melatonin (0, 50, 75, 100 µM) these plants later exposed (100 50 %). Results showed that reduced negatively affected various parameters such as leaf area, height, number, achene weight/plant, capitulum weight, total soluble sugars, catalase activity, anthocyanin, quercetin, gallic acid, vanillic chlorogenic acid cinnamic acid.

Low temperature storage is widely employed as primary method for preserving postharvest seeds during and transportation. This approach effectively extends life seeds, resulting in distinct physiological changes compared room storage, including notable reduction starch, protein, H2O2, MDA content. Here, we conducted RNA-sequencing generate global transcriptome profiles stored under or low conditions. Principal component analysis (PCA) revealed that gene expression demonstrated less variability comparison storage. A total 14,547 differentially expressed genes (DEGs) associated with various biological processes such starch sucrose metabolism, energy plant hormone signaling response were identified. Notably, levels DEGs involved ABA significantly suppressed contrast Additionally, nine weighted co-expression network (WGCNA)-based molecular modules identified, providing insights into relationship Our findings illuminate transcriptional differences between offering crucial mechanisms preservation
