AUX1-mediated root hair auxin influx governs SCFTIR1/AFB-type Ca2+ signaling
Abstract
Auxin regulates multiple aspects of plant growth and development. Here Dindas et al. show that in root-hair cells, the AUX1 auxin influx carrier mediates proton-driven auxin import that is perceived by auxin receptors and coupled to Ca2+ waves that may modulate adaptive responses in the root.
