Endogenous auxin biosynthesis and de novo root organogenesis

Abstract

Induction of adventitious roots is essential for vegetative propagation of plants, and auxin has long been used as an exogenous root-inducing agent. In this issue of Journal of Experimental Botany, Chen et al. (pages 4273-4284) demonstrate that different members of the YUCCA family orchestrate the endogenous auxin biosynthesis that is required for the induction of adventitious roots.
