Plant and animal development depend on both biochemical and biophysical responses. In certain contexts biochemical networks and gradients seem to be sufficient to explain patterning. However the translation of such patterns into shape changes also involves mechanical properties, which, in plants, largely depend on the characteristics of the structural elements, in particular the external matrix or cell wall. More generally, there is a number of emerging links between gene regulatory networks, biochemical gradients, and physical forces, involving multiple feedback loops. It is likely that combining mechanical signals and biochemical gradients could confer more robustness to plant development.
动植物的发育既依赖于生物化学反应，也依赖于生物物理反应。在某些情况下，生物化学网络和梯度似乎足以解释形态发生。然而，将这些模式转化为形状变化也涉及机械特性，而在植物中，机械特性在很大程度上取决于结构元素的特性，特别是外部基质或细胞壁。更一般地说，基因调控网络、生物化学梯度和物理力之间存在着许多新的联系，涉及多个反馈回路。将机械信号和生物化学梯度相结合，可能会使植物的发育更具鲁棒性。
