Welcome to Botany and Plant Pathology



We focus on fundamental aspects of plant biology; plant health, plant function, plant-microbe and plant-insect interactions, genomics, evolution, and ecology.

We are the primary research and extension unit within OSU addressing diseases of economically important plants in Oregon, and plant diseases of worldwide significance.

Cultivating excellence in plant biology through teaching, research, and outreach
