Arbuscular mycorrhiza (AM) is an ancient, widespread symbiosis between most land plants and fungi of the Glomeromycotina, which receives increasing interest for agricultural application because it can promote plant growth and yield. The ability of plants to react to AM with changes in morphology and/or performance in terms of yield is called 'AM responsiveness'. Its amplitude depends on the plant- fungal genotype combination and the abiotic and biotic environment. A molecular understanding of AM responsiveness is key for enabling rational application of AM in agriculture, for example through targeted breeding of AM-optimised crops. However, the genetic and mechanistic underpinnings of AM responsiveness variation remain still unknown. Here, we review current knowledge on AM responsiveness, with a focus on agricultural crops, and speculate on mechanisms that may contribute to the variation in AM response.
丛枝菌根（AM）是一种古老而广泛的共生现象，存在于大多数陆生植物和 Glomeromycotina 真菌之间，由于其能够促进植物生长和产量，因此越来越受到农业应用的关注。植物对丛枝菌根的反应能力表现为形态和/或产量方面的变化，被称为“丛枝菌根响应性”。其幅度取决于植物-真菌基因型组合以及非生物和生物环境。对丛枝菌根响应性的分子理解是在农业中合理应用丛枝菌根的关键，例如通过有针对性地培育丛枝菌根优化作物。然而，丛枝菌根响应性变化的遗传和机制基础仍然未知。本文综述了当前关于丛枝菌根响应性的知识，重点关注农业作物，并推测可能导致丛枝菌根响应变化的机制。
