TLDR NADPH oxidase and phospholipase D help root hairs grow by activating calcium channels.
The document discussed the role of signalling enzymes, specifically NADPH oxidase and phospholipase D, in the growth and development of root hairs in plants. It highlighted that reactive oxygen species (ROS) produced by NADPH oxidase activate calcium ion channels in the apical plasma membrane, which is crucial for establishing the tip-focused calcium gradient necessary for root hair growth. These findings provided insights into the previously unknown signalling events involved in root hair formation.
