Integrated multi-omics analysis reveals the molecular defense network underlying antimony tolerance in soybean. (PubMed, Plant Physiol Biochem) - Jul 18, 2026 - "Key components of this network, including genes (e.g., ABC transporters, PALs, CHIs, and PERs) and metabolites (e.g., isoliquiritigenin, chlorogenic acid, L-aspartate, L-glutamate), were identified as critical mediators. Functional validation via yeast heterologous expression demonstrated that GmCHI4, GmPER52, and GmPAL1 enhanced Sb tolerance, further supporting their roles within this defense network. These findings delineate a multi-layered molecular defense network and provide precise genetic and metabolic targets for breeding Sb-tolerant soybean cultivars."
