Abstract

gibberellin

cyclin D6;1

middle cortex

MicroRNA

ground tissue

root development

CYCD6;1

homeodomain leucin zipper III

Bertolotti, Unterholzner et al. show that a time-dependent threshold of the transcription factor PHB governs the timing of middle cortex formation in the Arabidopsis root. PHB promotes CYCD6;1 expression in the endodermis cell non-autonomously by reducing gibberellin (GA) levels in the vascular tissue and, hence, stabilizing the GAs repressor GAI.
