Abstract
Auxin is a potent hormonal effector of root hair development. A plethora of genetic and pharmacological studies have revealed that aberrations in auxin availability or signaling can cause defects in root hair growth and morphology. Recently identified components of auxin signaling and auxin transport have been implicated in root hair morphogenesis. The alteration of root hair morphogenesis by auxin also enables this single cell system to serve as an in planta biological marker through which the action mechanism of auxin can be examined.
