Drought stress substantially impacts the development and viability of Populus spp., which are essential for forestry bioenergy production. This review summarizes describes functions phytohormones, such as abscisic acid, auxins, ethylene, in modulating physiological molecular responses to water scarcity. Drought-induced ABA-mediated stomatal closure root extension adaptation processes. Furthermore, auxin–ABA (abscisic acid) interactions augment flexibility, whereas ethylene regulates antioxidant defenses alleviate oxidative stress. The advantageous function endophytic bacteria, specifically plant growth-promoting rhizobacteria (PGPR), can drought resistance spruce trees by enhancing nutrient absorption stimulating development. Structural adaptations encompass modifications architecture, including enhanced length density, uptake efficiency. Similarly, Arbuscular Mycorrhizal Fungi (AMF) significantly enhance resilience forest trees. AMF establishes symbiotic relationships with roots, improving uptake, particularly phosphorus, during conditions. morphological alterations at root–soil interface interaction soil moisture reserves. examines complex mechanisms these hormones influence shortage, aiming offer insights into prospective techniques tolerance common tree species highlights importance hormone control influencing adaptive prominent stress, providing significant implications research practical applications sustainable agriculture. These findings lay groundwork spp. biotechnological means illuminating hormonal networks that confer resistance.
