The Arbuscular Mycorrhizal (AM) symbiosis is a ubiquitous relationship established in terrestrial ecosystems between the roots of most plants and fungi of the Glomeromycota. AM fungi occur amongst many other inhabitants of the soil, and successful development of AM symbioses relies on a pre-symbiotic signal exchange that allows mutual recognition and reprogramming for the anticipated physical interaction. The nature of some of the signals has been discovered in recent years, providing a first insight into the type of chemical language spoken between the two symbiotic partners. Importantly, these discoveries suggest that the dialogue is complex and that additional factors and corresponding receptors remain to be unveiled. Here, we explore the latest advances in this pre-symbiotic plant-fungal signal exchange and present the resulting current understanding of rhizosphere communication in AM symbioses.
丛枝菌根（AM）共生是一种普遍存在于陆地生态系统中的关系，它是大多数植物的根部与 Glomeromycota 真菌之间建立的共生关系。AM 真菌存在于土壤中的许多其他生物中，AM 共生的成功发展依赖于共生前的信号交换，这种信号交换允许相互识别和重新编程，以进行预期的物理相互作用。近年来，一些信号的性质已经被发现，这为我们了解两个共生伙伴之间使用的化学语言类型提供了初步的认识。重要的是，这些发现表明这种对话是复杂的，还有其他因素和相应的受体有待揭示。在这里，我们探讨了这种共生前植物-真菌信号交换的最新进展，并介绍了目前对 AM 共生中根际通讯的理解。
