Reactive oxygen species act as signaling molecules to control root hair initiation and tip growth

open access: yesNew Phytologist, Volume 247, Issue 5, Page 2042-2048, September 2025.
Summary Root hairs (RHs) increase the surface area of roots, facilitating nutrient and water uptake and plant anchorage. RHs form from root epidermal cells and elongate by polar tip growth. Reactive oxygen species (ROS) have recently been implicated as important signals that drive RH formation and elongation using both genetic and imaging approaches ...
