香菇可以与丛枝菌根真菌（AMP）。这种共生关系涉及真菌和植物之间的分子对话，包括激活抗氧化剂，苯丙素或类胡萝卜素途径。本研究的目的是测试莴苣与AMF的关联是否有利于植物生长并增加对人类健康潜在有益的化合物的含量。结果表明，AMF促进了莴苣的生长，从而对一些矿物质营养素的浓度产生稀释效应（例如，Ca和Mn）。然而，菌根植物中的铜、铁、花色苷、类胡萝卜素以及较小程度的酚类化合物的浓度（以湿基计）高于非菌根植物。
Lettuce can be associated with arbuscular mycorrhizal fungi (AMP). This symbiosis involves a molecular dialogue between fungus and plant that includes the activation of antioxidant, phenylpropanoid, or carotenoid pathways. The objective of this study was to test if the association of lettuce with AMF benefited plant growth and increased the contents of compounds potentially beneficial for human health. Results showed that AMF improved growth of lettuce, thus producing a dilution effect on the concentrations of some mineral nutrients (e.g., Ca and Mn). However, Cu, Fe, anthocyanins, carotenoids, and, to a lesser extent, phenolics appeared in higher concentrations (on a wet basis) in mycorrhizal than in nonmycorrhizal plants.
