植物氮信号感知与根系发育

Nitrogen sensing and root development in plant

  • 摘要: 氮素是构成生物体的主要成分,也是植物体所需的重要营养元素,为应对土壤中氮素信号的波动,植物体必须通过一系列复杂信号通路来精密调控根部构型,以达到最优的氮吸收效率。本文综述了植物根部接收氮素信号的感受器以及其调控根系发育的具体途径,并详细阐述了氮信号通路、植物激素以及其他分子间的交互,为探究植物根系如何感知及响应氮信号提供新的研究思路。

     

    Abstract: Nitrogen is a major component of living organisms and an essential nutrient for plant growth. To cope with fluctuations in nitrogen signals in the soil, plants must finely regulate root architecture through a series of complex signaling pathways to optimize nitrogen uptake efficiency. This review summarizes the receptors involved in perceiving nitrogen signals in plant roots and the specific mechanisms regulating root development. It also elaborates on the cross-talk between nitrogen signaling pathways, plant hormones, and other molecules, providing new research perspectives on how plant roots perceive and respond to nitrogen signals.
