Brown Bag Seminar | Dr. Lydia Tymon | Powdery Mildew On Evergreen and Deciduous Rhododendron: Speciation In The Backyard*

October 9 @ 12:00 pm - 1:00 pm

Free

Dr. Lydia Tymon, Associate in Research and Plant Pathologist at WSU NWREC. In the Pacific Northwest (PNW), both deciduous and evergreen rhododendron occur sympatrically as landscape plants, and given their distinct overwintering strategies, it is possible that the number of powdery mildew fungi colonizing and infecting Rhododendron species in the PNW has been underestimated. Powdery mildew fungi infecting deciduous and evergreen rhododendron were collected from western Oregon, Washington, and Canada and morphologically and molecularly characterized. Analyses of concatenated ITS and 28S sequence data showed that powdery mildew fungi separate into two clades, suggesting that isolates infecting evergreen rhododendron are distinct from those infecting deciduous rhododendron.
