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.
土壤污染已成为全球各种陆地生态系统的主要关注点。最近，一种流行的原位土壤生物修复策略是微生物辅助植物修复，它有望修复污染物。鞘氨醇单胞菌是一种由四个知名属组成的多功能细菌群，普遍存在于受污染土壤中生长的植被中。这些革兰氏阴性微生物因其诱导植物固有生长促进 (PGP) 特性的能力而受到研究，包括植物激素、铁载体和螯合剂的形成，以及使它们能够进行生物降解和微生物辅助去除污染物的进化适应。然而，迄今为止，它们在细菌辅助植物修复方面的能力还没有得到充分重视。在这里，我们从未来植物生物技术的角度强调了鞘氨醇单胞菌在植物-微生物相互作用中的特定特征、作用、优势和挑战。
