生长素在微生物调控根发育过程中的作用

很多微生物通过分泌生长素和生长素前体与植物建立了有益的关系并改变植物根系的形态结构,此外,微生物分泌的其他代谢产物也能改变植物生长素信号通路。因此,生长素和生长素信号通路在微生物调控植物根系发育的过程中起着至关重要的作用。该文从生长素合成、生长素信号和生长素极性运输3个方面总结了生长素在微生物调控植物根系发育过程中的作用,主要包括微生物增加了植物内源生长素的含量、增强了生长素的信号和调控PIN蛋白的表达水平,进而如何调控植物生理和分子水平来适应微生物对其根系的改变,为进一步开展该方面的研究奠定了基础。

Role of Auxin in the Process of Microbe Control of Root Development

Microorganisms have established a beneficial relationship with the plants by secreting auxin and auxin precursors and alter plants root system architecture. Moreover, other metabolites are secreted by microorganisms can also change the plant auxin signaling pathway. Thus, auxin and auxin signaling pathways play an important role during the process of microbes modulate plant root development. This review summarizes the role of auxin during the process of microorganism regulate the development of plant root system from auxin synthesis, auxin signal and auxin polar transport, including microorganism increase the content of plant endogenous auxin, enhance the signal of auxin and regulate the expression level of PIN protein. Further, we concluded how microorganism regulated plant physiological and molecular level to adapt the changes of root system, which laid the foundation for further research in this field.
