The bacterium Paenibacillus polymyxa is found naturally in diverse niches. Microbiome analyses have revealed enrichment in the genus Paenibacillus in soils under different adverse conditions, which is often accompanied by improved growth conditions for residing plants. Furthermore, Paenibacillus is a member of the core microbiome of several agriculturally important crops, making its close association with plants an interesting research topic. This review covers the versatile interaction possibilities of P. polymyxa with plants and its applicability in industry and agriculture. Thanks to its array of produced compounds and traits, P. polymyxa is likely an efficient plant growth-promoting bacterium, with the potential of biofertilization, biocontrol and protection against abiotic stresses. By contrast, cases of phytotoxicity of P. polymyxa have been described as well, in which growth conditions seem to play a key role. Because of its adjustable character, we propose this bacterial species as an outstanding model for future studies on host-microbe communications and on the manner how the environment can influence these interactions.
多粘类芽孢杆菌天然存在于多种生态位中。微生物群落分析表明，在不同逆境条件下的土壤中，类芽孢杆菌属有所富集，这通常伴随着寄主植物生长条件的改善。此外，多粘类芽孢杆菌是几种重要农作物核心微生物群落的成员，其与植物的紧密联系成为一个有趣的研究课题。本综述涵盖了多粘类芽孢杆菌与植物的多种相互作用可能性及其在工农业中的应用。由于其产生的一系列化合物和特性，多粘类芽孢杆菌可能是一种高效的植物促生细菌，具有生物施肥、生物防治和抵御非生物胁迫的潜力。相比之下，也有关于多粘类芽孢杆菌产生植物毒性的报道，其中生长条件似乎起着关键作用。由于其具有可调节的特性，我们建议将这种细菌作为未来宿主 - 微生物通讯以及环境如何影响这些相互作用研究的杰出模型。
