Опубликована: Май 1, 2024

Abstract Phytohormones, pivotal regulators of plant growth and development, are increasingly recognized for their multifaceted roles in enhancing crop resilience against environmental stresses. In this review, we provide a comprehensive synthesis current research on utilizing phytohormones to enhance productivity fortify defence mechanisms. Initially, introduce the significance orchestrating growth, followed by potential utilization bolstering defences diverse stressors. Our focus then shifts an in‐depth exploration mediating responses biotic stressors, particularly insect pests. Furthermore, highlight impact agricultural production while underscoring existing gaps limitations hindering widespread implementation practices. Despite accumulating body field, integration into agriculture remains limited. To address discrepancy, propose framework investigating intricate interplay between sustainable agriculture. This advocates adoption novel technologies methodologies facilitate effective deployment settings also emphasizes need through rigorous field studies. By outlining roadmap advancing agriculture, review aims catalyse transformative changes practices, fostering sustainability settings.

Advances in Protein Kinase Regulation of Stress Responses in Fruits and Vegetables

International Journal of Molecular Sciences, Год журнала: 2025, Номер 26(2), С. 768 - 768

Опубликована: Янв. 17, 2025

Fruits and vegetables (F&Vs) are essential in daily life industrial production. These perishable produces vulnerable to various biotic abiotic stresses during their growth, postharvest storage, handling. As the fruit detaches from plant, these become more intense. This unique biological process involves substantial changes a variety of cellular metabolisms. To counter stresses, plants have evolved complex physiological defense mechanisms, including regulating activities through reversible phosphorylation proteins. Protein kinases, key components protein phosphorylation, facilitate transfer γ-phosphate group adenosine triphosphate (ATP) specific amino acid residues on substrates. alters proteins’ structure, function, interactions, thereby playing crucial role activity. Recent studies identified kinases F&Vs, underscoring significant roles plant development, stress responses. article reviews types found emphasizing regulatory mechanisms managing research sheds light involvement metabolic regulation, offering insights advance quality characteristics F&Vs.

The Multifaceted Role of Jasmonic Acid in Plant Stress Mitigation: An Overview

Plants, Год журнала: 2023, Номер 12(23), С. 3982 - 3982

Опубликована: Ноя. 27, 2023

Plants, being sessile, have developed complex signaling and response mechanisms to cope with biotic abiotic stressors. Recent investigations revealed the significant contribution of phytohormones in enabling plants endure unfavorable conditions. Among these phytohormones, jasmonic acid (JA) its derivatives, collectively referred as jasmonates (JAs), are particular importance involved diverse signal transduction pathways regulate various physiological molecular processes plants, thus protecting from lethal impacts Jasmonic has emerged a central player plant defense against stress alleviating multiple stressors such drought, salinity, vernalization, heavy metal exposure. Furthermore, growth regulator, JA operates conjunction other through cascade balance development stresses. Although studies reported intricate nature biomolecular entity for mitigation stressors, their underlying mechanism biosynthetic remain poorly understood. Therefore, this review offers an overview recent progress made understanding biosynthesis JA, elucidates complexities pathways, emphasizes pivotal role mitigating Moreover, we also discuss current issues future research directions JAs responses.

Jasmonate enhances cold acclimation in jojoba by promoting flavonol synthesis

Horticulture Research, Год журнала: 2024, Номер 11(7)

Опубликована: Май 3, 2024

Abstract Jojoba is an industrial oil crop planted in tropical arid areas, and its low-temperature sensitivity prevents introduction into temperate areas. Studying the molecular mechanisms associated with cold acclimation jojoba advantageous for developing breeds enhanced tolerance. In this study, metabolomic analysis revealed that various flavonols accumulate during acclimation. Time-course transcriptomic weighted correlation network (WGCNA) demonstrated flavonol biosynthesis jasmonates (JAs) signaling pathways played crucial roles Combining biochemical genetic analyses showed ScMYB12 directly activated synthase gene (ScFLS). The interaction between transparent testa 8 (ScTT8) promoted expression of ScFLS, but negative regulator ScJAZ13 JA pathway interacted ScTT8 to attenuate transcriptional activity complex, leading downregulation ScFLS. Cold stimulated production leaves, degradation ScJAZ13, complexes, accumulation flavonols. Our findings reveal mechanism JA-mediated highlight as a promising means enhancing tolerance breeding efforts.

Response of amino acids, phenolic acids, organic acids, and mineral elements to fulvic acid in spinach (Spinacia oleracea L.) under nitrate stress

Scientific Reports, Год журнала: 2025, Номер 15(1)

Опубликована: Март 19, 2025

Abstract Fulvic acid (FA) has many physiological activities, but the specific metabolic responses and changes in mineral element contents of spinach by FA response to nitrate stress are unknown. Herein, we used liquid chromatography-mass spectrometry (LC–MS) wet digestion using H 2 SO 4 -H O analyze content (150 mM NO 3 − ) after (0.15%) foliar spray application. After days treatment, was sprayed thrice (once every 7 days), sampled last spraying, metabolites were measured. treatment significantly increased organic (tartaric acid, malic citric ascorbic acid) amino (threonine, asparagine, valine, tyrosine, alanine, glutamate, serine, histidine, arginine, glutamine) under stress. application also improved (P, Na, Fe, Zn) This study provides comprehensive insights into metabolite accumulation improvement nutritional quality through Further research should focus on elucidating additional underlying molecular mechanisms these for better utilization this natural compound agriculture.
