Plant development: how long is a root?

Curr Biol. 2012 Nov 6;22(21):R919-21. doi: 10.1016/j.cub.2012.09.048.

Abstract

The plant hormone cytokinin controls root growth by balancing the division and differentiation of stem cells. But what controls accumulation of cytokinin? A new study has identified a regulatory loop between a transcription factor, PHABULOSA, and cytokinin biosynthesis that creates robust domains of cytokinin activity.
