Published: Jan. 13, 2025

Plants must effectively respond to various environmental stimuli achieve optimal growth. This is especially relevant in the context of climate change, where drought emerges as a major factor globally impacting crops and limiting overall yield potential. Throughout evolution, plants have developed adaptative strategies for stimuli, with plant hormones reactive oxygen species (ROS) playing essential roles their development. Hormonal signaling maintenance ROS homeostasis are interconnected, indispensable growth, development, stress responses orchestrating diverse molecular during adversities. Nine principal classes phytohormones been categorized: auxins, brassinosteroids, cytokinins, gibberellins primarily oversee developmental growth regulation, while abscisic acid, ethylene, jasmonic salicylic strigolactones main orchestrators responses. Coordination between transcriptional regulation crucial effective responses, stress.

The emergence of antimicrobial resistance (AMR) has urged researchers to explore therapeutic alternatives, one which includes the use natural plant products such as essential oils (EO). In fact, EO obtained from clove, oregano, thymus, cinnamon bark, rosemary, eucalyptus, and lavender have been shown present significant inhibitory effects on bacteria, fungi, viruses; many studies done measure efficacy against microorganisms. strategy combinatory via conventional non-conventional methods revealed that combined EO-EO or EO-antibiotic exhibit enhanced efficacy. This paper aims review EO, modes action (membrane disruption, efflux inhibition, increase membrane permeability, decrease in intracellular ATP), their compounds' potential effective agents viruses. It is hoped integration applications this work can be used consider for future clinical applications.
