As genomics research unravels some of life’s complexities, laboratories like the new molecular lab at WSU Puyallup applies that knowledge to real-world problems.
For molecular geneticist Katie Coats, that means working with the WSDA and WSU Puyallup plant pathologist Gary Chastagner to understand the genetics of the exotic plant pathogen Phytophthora ramorum, the cause of sudden oak death. This fungus-like pathogen has killed more than a million oak trees in California and has been found in a number of Puget Sound nurseries. If uncontrolled, this pathogen can spread through air and water to other trees and plants in nurseries and into surrounding … » More …
