Transcriptomic profiling of roots reveals species-specific adaptive strategies in maize and soybean intercropping

Short summary

Intercropping maize and soybean triggers species-specific root transcriptomic changes: maize upregulates nitrogen/carbon metabolism genes (e.g., NRT2.1, NR) and increases root biomass, while soybean extensively downregulates phenylpropanoid/flavonoid pathways and enhances individual nodule function (21% higher leghemoglobin content).
