Aluminum (Al) toxicity inhibits plant growth and alters gene expression metabolite profiles. However, the molecular mechanisms underlying effects of Al on peanut plants remain unclear. Transcriptome metabolome analyses were conducted to investigate responses leaves roots toxicity. significantly inhibited growth, disrupted antioxidant enzyme systems in leaves, impaired nutrient absorption. Under stress, content indole-3-acetic acid-aspartate (IAA-Asp) decreased by 23.94% but increased 12.91% roots. Methyl jasmonate (MeJA) levels dramatically 2642.86%. salicylate (MeSA) 140.00% 472.22%, respectively. Conversely, isopentenyl adenosine (IPA) 78.95% 20.66% analysis identified 5831 differentially expressed genes (DEGs) 6405 DEGs roots, whereas metabolomics revealed 210 accumulated metabolites (DAMs) 240 DAMs both enriched "linoleic acid metabolism" pathway. Genes such as lipoxygenase LOX1-5 LOX2S expressed, metabolites, including linoleic its oxidized derivatives, accumulated, mitigating oxidative stress. This study elaborates potential complex physiological peanuts under aluminum highlights importance metabolism coping with These findings enhance our understanding impact development response key metabolic pathways, providing targets for genetic engineering improve crop resistance
