Abstract

Root exudation is the process by which plants release organic and inorganic metabolites from their roots into the surrounding soil. Root exudation is a dynamic process and shapes plant-environment interactions at the root-soil interface. Little is known about the biological and environmental factors that shape the exuded metabolome, hereafter referred to as the exudome, despite its importance in structuring soil processes. Here, we emphasize plant physiological and morphological traits that modulate the exudome in a species- and developmental stage-specific manner. We further discuss how environmental factors drive exudation processes. We highlight evidence of a potential circadian exudation rhythm and further illustrate how the physical (temperature, structure), chemical (moisture, pH, nutrients, pollutants), and biological (micro- and macrofauna) properties of soil alter the root exudome composition and release patterns. Exploring the factors that directly or indirectly modulate exudation will enhance our understanding of how this dynamic process mediates plant-environment interactions.

根系渗出的环境和生物驱动因素。
根系渗出是植物从根系向周围土壤释放有机和无机代谢物的过程。根系渗出是一个动态过程,它决定了根-土界面上植物与环境的相互作用。尽管渗出代谢组在构建土壤过程中很重要,但对形成渗出代谢组的生物和环境因素知之甚少,以下简称渗出代谢组。在这里,我们强调植物的生理和形态特征,以物种和发育阶段特定的方式调节渗出体。我们进一步讨论了环境因素如何驱动渗出过程。我们强调了潜在的昼夜节律的证据,并进一步说明了土壤的物理(温度,结构),化学(湿度,pH值,营养物质,污染物)和生物(微型和大型动物)特性如何改变根渗出物的组成和释放模式。探索直接或间接调节渗出的因素将增强我们对这一动态过程如何介导植物与环境相互作用的理解。
