title: Plant development: how long is a root?
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.
