Abstract

Rhododendron maximum L. and R. catawbiense Michx. are two species that are native to the eastern United States. They can be found throughout the Appalachian Mountain range and during bloom are very important tourist attractions. Phytophthora ramorum is known to be pathogenic to both species, although no symptoms have been observed in wild habitats in the eastern United States. Endophytic fungi are known to have a symbiotic relationship with their host, including protection against pathogens. It was the purpose of this study to survey natural stands of R. maximum and R. catawbiense in the eastern United States in order to understand what endophytic fungi are present and whether they have the potential to protect against P. ramorum infection.
