图4. 植物与菌根真菌共生关系分子模式图(参考Martin等(2017))。根系分泌信号分子(①), 促进土壤中丛枝孢子(②)的萌发和菌丝分枝; AMF分泌的菌根因子(③)被根系上的受体(④)识别并激活钙离子信号通路(⑤), 进而形成侵染线(⑥); 菌根真菌菌丝侵入根细胞后, 与根系进行碳-养分交换, 这中间涉及一系列酶和转运蛋白(⑦)的共同作用。

Fig. 4. Conceptual model for the symbiotic relationship between plants and mycorrhizal fungi (adapted from Martin et al., 2017). Roots secrete signaling molecules (①) promote germination of AMF spores (②) and mycelium branching in the soil; mycorrhizal factors secreted by AMF (③) are recognized by receptor proteins in root cells (④), and then activate the calcium signaling pathway (⑤) to initiate formation of invasion lines of the mycorrhizal fungi (⑥). After that, the carbon and nutrient exchange between mycorrhizae and root cells also requires a series of enzymes and transport proteins in the root-mycorrhiza interface (⑦).
