植物与丛枝菌根真菌(Arbuscular Mycorrhizal Fungi, AMF)共生是自然界中最常见的共生现象之一。菌根共生促进植物磷营养吸收,同时植物以脂肪酸和糖的形式给菌根真菌提供其发育所需的碳源。菌根真菌在根的皮层细胞中形成高度分支的树形结构,称为丛枝。丛枝是共生体间双向营养交换的中介,被认为是共生体的核心功能单位。提高菌根共生介导的营养吸收对植物本身的生长具有重大意义。本文概述了植物和丛枝菌根真菌建立共生的过程,并总结了在共生关系中起关键作用的重要蛋白,为丛枝菌根共生的研究提供理论基础。
Symbiosis between plants and arbuscular mycorrhizal fungi (AMF) is one of the most common symbiosis phenomena in nature. Mycorrhizal symbiosis promotes phosphorus nutrient absorption by plants, and at the same time, plants provide mycorrhizal fungi with carbon sources needed for their development in the form of fatty acids and sugars. Mycorrhizal fungi form highly branched tree-like structures called arbuscules in the cortical cells of the roots. Arbuscules are the mediators of two-way nutrient exchange between symbionts and are considered to be the core functional unit of symbionts. Improving mycorrhizal symbiosis-mediated nutrient uptake is of great significance to the growth of the plant itself. This article outlines the process of establishing symbiosis between plants and arbuscular mycorrhizal fungi, and summarizes the important proteins that play a key role in the symbiotic relationship, providing a theoretical basis for the study of arbuscular mycorrhizal symbiosis.
