OsERF27 and its downstream target OsPLT4 form a regulatory module that is required for timely proximal crown root development in rice (Oryza sativa), linked to spatial ROS homeostasis.
- Why it matters: Crown roots arise from stem-base phytomers and split into proximal and distal populations with distinct timing, but how positional cues coordinate this temporospatial patterning is unclear.
- What they did: The study identifies OsERF27 as differentially expressed between proximal and distal primordia, tests its requirement for proximal root timing, and places OsPLT4 downstream to control proximal outgrowth and emergence.
- The result: Loss-of-function mutants show disturbed ROS accumulation patterns and increased sensitivity of crown root formation to ROS perturbation, implying the module promotes emergence by maintaining spatial redox balance.
