Integrating Remote Sensing and Metabolomics to Assess Synergistic Effects of Phosphate Deficiency, Drought, and AMF Symbiosis in Soybean.

ABSTRACT: Soybean growth and yield are susceptible to abiotic stresses such as phosphate (P) deficiency and drought. Symbiotic association of plant roots with arbuscular mycorrhizal fungi (AMF) can improve water uptake, thereby increasing stress resilience. This study evaluates the interactive effects of P availability, drought, and AMF symbiosis on physiology, reflectance traits, roots, and metabolite responses in two soybean genotypes during the early reproductive stages. Under P deficiency (P-), AMF colonization significantly (p < 0.05) increased, enhancing root hair development and maintaining ~30% lower leaf water potential (Ψ) under drought stress. Drought significantly (p < 0.05) negatively impacted photosynthesis as well as triggered shifts in metabolite accumulation and reflectance-based ve
