Maize root system architecture improvement for high-density planting

Appropriate root system architecture (RSA) is essential for efficient water and nutrient use, especially in high-density planting conditions in intensive maize cropping systems. Modern maize breeding has favoured steeper, narrower root systems. We identified two auxin-related genes, ZmRSA3.1 and ZmRSA3.2, which can potentially be used for future improvement of maize RSA.
