Integrated transcriptome-metabolome analysis reveals a GmMYB093-GmCYP90A1-BR module supporting soybean adaptation to iron deficiency.
An entropy-weight-based evaluation system is established and a model in which the GmMYB093-GmCYP90A1-BR module contributes to soybean low-Fe adaptation by coordinating Fe homeostasis, redox protection, and root-nodule performance is supported, providing candidate targets for breeding Fe-efficient soybean cultivars.
