This study aims to identify the molecular mechanisms by which soybean responds to manganese (Mn) stress through an integrated multi-omics approach.
Applied a multi-omics approach analyzing transcriptomic and metabolomic responses in soybean under varying Mn concentrations (5 µM and 100 µM).
Quantified changes in gene expression (5045 differentially expressed genes) and metabolite accumulation (3259 differentially accumulated metabolites).
Observations of physiological traits and ion content in soybean exposed to Mn toxicity.
Mn content increased by 7.4 times in roots and 7.7 times in leaves under 100 µM Mn stress.
Leaf glutathione content decreased by 35.68% and hydrogen peroxide content reduced by 53.54%.
Phenylalanine ammonia-lyase activity increased by 83.15% in roots, indicating enhanced stress response pathways.
