Where this comes from

Abstract

The detachment of plant organs is highly choreographed, requiring the enzymatic dissolution of the middle lamella between cell layers at the base of the detaching organ. Now, Lee et al. demonstrate that abscission efficiency and plant health rely on the spatial confinement of enzymatic activity and mechanical features that ensure a smooth separation.
