Rhododendron study system

Our research on the ecophysiology of stress tolerance in Rhododendron was funded by the National Science Foundation (DEB 2217714).

Ph.D. student Yu Liu's research is exploring the role of soil biota in disease resistance to the devastating pathogen root rot (Phytophthora cinnamomi) in Rhododendron (Liu et al. 2021, Liu et al. 2023).

RA-LEAFY

We are piloting a community scientist database for leaf traits in Rhododendrons and Azaleas. See the R-RN newsletter for more.

Jean serves on the steering committee for this international research network, initiated by collaborator Juliana Medeiros, at Holden Arboretum.
