Feeling UPBEAT about Growth: Linking ROS Gradients and Cell Proliferation

Darren M. Wells, Michael H. Wilson & Malcolm J. Bennett

Recent work in animals and plants suggests that reactive oxygen species (ROS) control cell proliferation. Reporting in Cell, Tsukagoshi et al. (2010) identify UPBEAT1 as a key transcription factor in the regulation of ROS distribution, which they find controls the transition between cell proliferation and differentiation in the Arabidopsis root.
