- 🌱 How do maize roots know where water is in dry soils... and why don’t all crops do this equally well?? Recap of the #HS Science paper "Moisture-responsive root-branching pathways identified in diverse maize breeding germplasm"💧🌿 📄 Full paper: www.science.org/doi/abs/10.1... 👇 1/3

- Maize #roots actively pattern new branches toward water (hydropatterning), but this response differs across varieties. Some key findings: 1. Maize shows genetic diversity in hydropatterning, with tropical/subtropical lines exhibiting stronger responsive root branching. 👇 2/3
- 2. This divergence likely reflects different historical selection pressures during modern breeding. 3. Auxin promotes root branching toward moisture, while ethylene suppresses branching on air-exposed root surfaces. 3/4
- 4. These signaling pathways translate environmental water patterns into root architecture with clear field relevance. 🤔 These insights into moisture-responsive root growth could help improve drought resilience in crops. #Maize #PlantScience 📄 Full paper: www.science.org/doi/abs/10.1... 4/4
