Rare taxa as the major drivers of the secondary metabolite accumulation in Rheum tanguticum.

Summary: Have you ever wondered what makes medicinal plants so special? It turns out, the secret might be hidden in the dirt! Scientists studied a unique plant from the Qinghai-Tibet Plateau called Rheum tanguticum. They found that rare, hard-to-find fungi living in the soil and on the plant's leaves act like tiny helpers. These rare fungi are the main reason the plant's roots build up the special chemicals that make it a good medicine. By taking care of these rare fungi, we can help grow better medicinal plants in the future!
