With the warming global climate, drought stress is considered to be the most important abiotic factor limiting plant growth and yield in the world. Drought stress has serious impacts on crop production. Many researchers have studied the influences of drought stress on crop production and plant physiology; however, few researchers have combined root exudates with root-associated microbiomes for their mutual effects under drought conditions. In this review, we systematically illustrate the impact of drought stress on root exudates and root-associated microbiomes, and then we discuss the mutual regulation of root-associated microbiomes and the host plant in helping the plant adapt to drought. Finally, we construct a framework for the mutual connections between the plant, root exudates, and the microbiome. We hope this review can provide some significant guidelines to promote the study of drought resistance in plants in association with the rhizosphere microbiota.
随着全球气候变暖，干旱胁迫被认为是世界上限制植物生长和产量的最重要的非生物因素。干旱胁迫对作物生产有严重影响。许多研究人员研究了干旱胁迫对作物生产和植物生理学的影响；然而，很少有研究人员将根分泌物与根相关微生物组结合起来，研究它们在干旱条件下的相互作用。在这篇综述中，我们系统地说明了干旱胁迫对根分泌物和根相关微生物组的影响，然后讨论了根相关微生物组与宿主植物在帮助植物适应干旱方面的相互调节。最后，我们构建了一个植物、根分泌物和微生物组之间相互联系的框架。我们希望这篇综述能为促进与根际微生物群相关的植物抗旱性研究提供一些重要的指导。
