植物中钙信号介导的硝酸盐信号途径的研究进展

Advances in the study of calcium signaling-mediated nitrate signaling in plants

  • 摘要: 硝酸盐不仅是植物的主要氮源,而且是植物极为重要的信号分子,参与众多生理生化反应、代谢过程,调控植物的生长和发育。研究发现钙信号参与初级硝酸盐响应过程,然而关于钙信号如何参与硝酸盐信号的感知和硝酸盐信号的传递过程尚未清楚。本文综述了具有钙离子通道活性的环核苷酸门控通道与硝酸盐转运体复合体(Cyclic nucleotide-gated channel 15-nitrate transceptor 1.1,CNGC15-NRT1.1)、钙调磷酸酶B类蛋白(Calcineurin B-like protein,CBL)、CBL互作蛋白激酶(CBL-interacting protein kinases,CIPKs)、钙依赖蛋白激酶(Calcium-dependent protein kinases,CPKs)和磷脂酶C (Phospholipase C,PLC)如何从细胞膜到细胞核参与植物的硝酸盐信号过程,从而形成相对完整的硝酸盐信号网络。并对未来钙信号如何连接上游硝酸盐传感器复合体与下游硝酸盐信号通路的多个传感器,从而完成营养生长调控网络的研究方向进行了展望。

     

    Abstract: Nitrate is not only the main nitrogen source in plants, but also an extremely important signaling molecule. Nitrate signaling integrates and coordinates the expression of a wide range of genes, metabolic pathways, and ultimately, plant growth and development. Calcium signaling is involved in the primary nitrate response pathway. However, how calcium signaling mediates nitrate sensing and signaling from the extracellular space to the cytoplasm and nucleus is much less understood. In this review, we describe how cyclic nucleotide-gated channel 15-nitrate transceptor 1.1 (CNGC15-NRT1.1), calcineurin B-like protein (CBL), CBL-interacting protein kinases (CIPKs), calcium-dependent protein kinases (CPKs), and phospholipase C (PLC) act as key players and the potential backbone of the nitrate-signaling pathway, from the plasma membrane to the nucleus. We also discuss future directions for studying how calcium signaling interconnects the upstream nitrate sensor complex with downstream multiple sensors of the nitrate-signaling pathway to complete nutrient-growth regulatory networks.
