Native AMF from wild Paeonia ostii enhance root development via PoCCD4-mediated hormone homeostasis and reshape rhizosphere microbiome assembly and function.
Arbuscular mycorrhizal fungi (AMF) play vital roles in plant growth and rhizosphere microbiome assembly. Tree peony (Paeonia sect. Moutan DC.) is an economically valuable perennial crop, yet the symbiotic mechanisms between it and native AMF remain poorly understood. In this study, we surveyed the rhizosphere AMF commu...
