The increasing global population has heightened the demand for food, leading to escalated food production and, consequently, generation of significant waste. Factors such as rapid ripening, susceptibility physiological disorders, and vulnerability microbial attacks have been implicated contributing accelerated senescence associated with waste generation.

Water scarcity and climate change pose significant challenges to sustainable agriculture, emphasizing the need for optimized irrigation practices. This study evaluates impact of limited (0.45 L/day per plant) compared a control (0.87 on tomato fruit quality metabolic responses. Limited enhanced flavor by reducing pH from 4.2 3.4 improved cellular integrity, with electrolyte leakage decreasing 50% 26%. Antioxidant levels increased, vitamin C content rising 49 64 mg 100 g−1 FW, while glucose fructose accumulation contributed sweetness. Notably, suppressed ethylene biosynthesis, methionine, ACC, ACO activity, production, which are key regulators ripening senescence. suppression suggests potential extending shelf life delaying over-ripening. These findings underscore dual benefits irrigation: enhancing supporting water use. research provides viable strategy optimizing production postharvest in water-limited regions.

Ethylene is an essential plant hormone critical in various physiological processes. These processes include seed germination, leaf senescence, fruit ripening, and the plant's response to environmental stressors. biosynthesis tightly regulated by two key enzymes, namely 1-aminocyclopropane-1-carboxylate synthase (ACS) oxidase (ACO). Initially, prevailing hypothesis suggested that ACS limiting factor ethylene pathway. Nevertheless, accumulating evidence from studies has demonstrated ACO, under specific circumstances, acts as rate-limiting enzyme production. Under normal developmental processes, ACO collaborate maintain balanced production, ensuring proper growth physiology. However, abiotic stress conditions, such drought, salinity, extreme temperatures, or pathogen attack, regulation of becomes for plants’ survival. This review highlights structural characteristics, examines transcriptional, post-transcriptional, post-translational their role conditions.

ACS (1-aminocyclopropane-1-carboxylic acid synthase) is a member of the aminotransferase superfamily and pyridoxal phosphate-dependent enzyme. also rate-limiting enzyme for biosynthesis ethylene has been linked with plant development, growth, stress responses. However, information on genes in soybean genome limited. In this study, we identified through phylogenetic trees conserved motifs analyzed their cis-acting elements, subcellular localization, expression patterns. Twenty-two members family were soybean, they divided into four subfamilies based relationships. Moreover, results Arabidopsis mesophyll protoplasts showed that GmACS1, GmACS8, GmACS15 all localized nucleus cell membrane. Cis-regulatory elements qRT-PCR analyses indicated markedly increased levels GmACS transcripts under hormone treatments abiotic conditions (drought, alkalinity, salt). addition, different stresses, potential functional variations across isoforms mirrored differential expression.

The application of 1-methylcyclopropene (1-MCP) is widely used to extend the storage life climacteric fruits, such as ‘Rocha’ pears. However, suppression ethylene’s action by 1-MCP often results in excessive ripening delay, compromising fruit quality and consumer acceptance. In this study, we investigated potential glyoxylic acid (GLA) counteract effects promote ripening. To evaluate this, pears treated with were exposed 3% (m/v) GLA stored at 20 ± 2 °C for 15 days. Typical indicators, firmness, skin color, ethylene production, respiration rate, volatile organic compounds (VOCs), sugars, activity biosynthetic enzymes, measured. Our indicate that did not induce significant on response, production remained comparable control. Consequently, no changes yellowing, or sugar content observed GLA-treated significantly increased rates (approximately 57%) induced higher emissions stress-associated VOCs, including hexanal, (E)-2-hexenal, ethanol.
