Hydraulic flux–responsive hormone redistribution determines root branching (2022)
Journal Article
Mehra, P., Pandey, B. K., Melebari, D., Banda, J., Leftley, N., Couvreur, V., …Bennett, M. J. (2022). Hydraulic flux–responsive hormone redistribution determines root branching. Science, 378(6621), 762-768. https://doi.org/10.1126/science.add3771

Plant roots exhibit plasticity in their branching patterns to forage efficiently for heterogeneously distributed resources, such as soil water. The xerobranching response represses lateral root formation when roots lose contact with water. Here, we s...
