Early developmental plasticity of lateral roots in response to asymmetric water availability

Root branching is influenced by the soil environment and exhibits a high level of plasticity. We report that the radial positioning of emerging lateral roots is influenced by their hydrological environment during early developmental stages. New lateral root primordia have both a high degree of flexibility in terms of initiation and development angle towards the available water. Our observations reveal how the external hydrological environment regulates lateral root morphogenesis.

植物根的分枝受土壤环境的影响，并表现出很高的可塑性。本文中，作者发现在早期发育阶段，新形成的侧根的径向定位受到根系周边水文环境的影响。新的侧根原基在起始和发育角度上都对于可用水方向具有高度的灵活性。作者的观察揭示了植物根系外部水文环境如何调节侧根的形态发生。
