Feeling UPBEAT about Growth: Linking ROS Gradients and Cell Proliferation
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.
