Abstract:
How do plants make species-specific leaves and flowers with stereotypical size and shape? A new study in Developmental Cell finds that local spatiotemporal variability in cell growth rate is essential for robustness in organ geometry control, and reactive oxygen species act to suppress this local heterogeneity during organ maturation.
