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.

Abstract Hydrogen sulfide (H 2 S) has emerged as a novel endogenous gas signaling molecule, joining the ranks of nitric oxide (NO) and carbon monoxide (CO). Recent research highlighted its involvement in various physiological processes, such promoting root organogenesis, regulating stomatal movement photosynthesis, enhancing plant growth, development, stress resistance. Tobacco, significant cash crop crucial for farmers’ economic income, relies heavily on development to affect leaf disease resistance, chemical composition, yield. Despite importance, there remains scarcity studies investigating role H S tobacco growth. This study exposed seedlings different concentrations NaHS (an exogenous donor) − 0, 200, 400, 600, 800 mg/L. Results indicated positive correlation between concentration length, wet weight, activity, antioxidant enzymatic activities (CAT, SOD, POD) roots. Transcriptomic metabolomic analyses revealed that treatment with 600 mg/L significantly effected 162 key genes, 44 enzymes, two metabolic pathways (brassinosteroid synthesis aspartate biosynthesis) seedlings. The addition not only promoted but also potentially reduced pesticide usage, contributing more sustainable ecological environment. Overall, this sheds light primary involved response NaHS, offering new genetic insights future investigations into development.

Flowering is a critical step in the plant life cycle. Angelica sinensis (Oliv.) Diels medicinal crop whose root well-known herbal medicine used Asia. Early flowering causes changes secondary metabolic flow and results loss of quality. Based on untargeted metabolomics studies, quinic acid was identified as metabolite present significantly higher concentrations during early-flowering stage A. leaves. This subsequently investigated potential marker for early bolting under field conditions. Moreover, found to accelerate model Arabidopsis thaliana. Importantly, time delayed quinate dehydrogenase At mutant, this delay reversed by acid. Quinic upregulated expression GA20OX GID1 receptors downregulated inhibitor DELLA, thereby affecting levels FT LFY accelerating flowering. also changed genes such LOX, JAZ1, MYC2 MYC3 jasmonic pathway. The trends GID1, DELLA (GAI) LOX2 protein were essentially consistent with those at transcription level. These suggest that may promote primarily regulating proteins gibberellin pathways.
