East Asian wintergreen
Pyrola japonica
Pyrola japonica is a plant traditionally found in East Asia and Japan. While it has not been used for medicinal purposes according to historical records, studies have explored its ecological role. Research indicates that Pyrola japonica exhibits high alpha diversity but lower beta diversity in its mycorrhizal communities compared to co-occurring autotrophic trees. The fungicide treatment affects the mycorrhizal fungal pathways via extraradical hyphae, leading to increased photosynthetic behavior in P. japonica leaves and seeds. Additionally, the rhizosphere bacterial community composition changes with different mycorrhizal development stages of Pyrola japonica, and varying phenotypes exhibit differing degrees of mycoheterotrophy, particularly with albinos showing fully mycoheterotrophic nutrition. To date, no major safety issues or drug interactions have been recorded for this plant.
