In their 2025 Science Advances study, Li et al. identified ZmbZIP89, a cortex- and epidermis-specific transcription factor, as a key regulator of lateral root elongation and drought resilience in maize. Natural variation in its 3'UTR enhances expression by stabilizing mRNA, promoting ZmPRX47-mediated ROS homeostasis and adaptive root traits, as revealed through integrated association and single-cell transcriptomic analyses. These insights reveal promising targets for engineering root traits toward climate-resilient crop development.
