Soil pollution has become a major concern in various terrestrial ecosystems worldwide. One in situ soil bioremediation strategy that has gained popularity recently is microbe-assisted phytoremediation, which is promising for remediating pollutants. Sphingomonads, a versatile bacteria group comprising four well-known genera, are ubiquitous in vegetation grown in contaminated soils. These Gram-negative microbes have been investigated for their ability to induce innate plant growth-promoting (PGP) traits, including the formation of phytohormones, siderophores, and chelators, in addition to their evolutionary adaptations enabling biodegradation and microbe-assisted removal of contaminants. However, their capacity for bacterial-assisted phytoremediation has to date been undervalued. Here, we highlight the specific features, roles, advantages, and challenges associated with using sphingomonads in plant–microbe interactions, from the perspective of future phytotechnologies.

土壤污染已成为全世界各种陆地生态系统中的主要问题。一个原位最近已经流行的土壤生物修复策略是微生物辅助植物修复，有望修复污染物。Sphingomonads是由四个著名属组成的通用细菌群，在受污染的土壤中生长的植被中普遍存在。研究了这些革兰氏阴性微生物诱导植物先天生长（PGP）特性的能力，包括植物激素，铁载体和螯合剂的形成，此外还具有进化适应性，可实现生物降解和微生物辅助去除污染物。然而，迄今为止，它们的细菌辅助植物修复能力被低估了。在这里，我们重点介绍了在植物与微生物的相互作用中使用鞘氨醇单胞菌相关的特定特征，作用，优势和挑战，
