DING1 Mediates DCPTA‐Enhanced Nodulation in Soybean Symbiosis

Summary statement Research reveals that DCPTA treatment boosts soybean nodulation and pinpoints the nodule‐specific gene GmATL31 as essential for this process, where it functions by enhancing symbiotic signaling and nutrient metabolism. These findings offer a genetic strategy and theoretical foundation for using DCPTA to improve biological nitrogen fixation in legumes, potentially reducing reliance on chemical fertilizers.
