Analysis of cambial development in the tree Populus trichocarpa reveals how a zinc-finger transcription factor, Populus trichocarpa VASCULAR CAMBIUM-SPECIFIC 2 (PtrVCS2), controls the rate of cell proliferation by changing the dynamics of histone acetylation at the Populus trichocarpa WUSCHEL-RELATED HOMEOBOX4a (PtrWOX4a) promoter.
