Abstract
Early AMF colonization imposes a metabolic cost, delaying physiological recovery. Seed priming facilitates gradual symbiotic onset, reducing metabolic disruption. AMF influences plant metabolism, modulating biosynthetic pathways and exudation profiles. Symbiosis fully establishes after 27 days, influencing microbiome composition. Resource allocation shifts toward secondary metabolism and recruitment compounds.
