Growth couples temporal and spatial fluctuations of tissue properties during morphogenesis.

How do organs and organisms grow and achieve robust shapes in the face of subcellular and cellular variability is still a mystery. Here we investigated the variability of growth at multiple scales and we analysed experimental growth data from growing plant tissues. Our results support the prediction that tissue expansion couples temporal memory of growth with spatial variability of growth. Our work reveals a constraint on spatiotemporal variability of growth that may impact the robustness of morphogenesis.
