Using black cottonwood (Populus trichocarpa) a native tree to the western US, Ryan is working to reveal the genes responsible for making woody plants susceptible to fungal disease and those that give the fungus the ability to infect trees. The fungus of interest, Sphaerulina musiva, causes leaf spot and stem canker on cottonwood trees, the latter disease being more severe as it girdles the trees and causes the tops to break off. To learn how the tree and fungus interact, Ryan employs advanced molecular techniques like the CRISPR-Cas9 system to edit genes. To put it simply, he tries to find the important information in the plant and fungus by making changes in the genetic code and then seeing if it has a downstream effect. As a model system, the secrets of the black cottonwood would be unveiled, providing a blueprint of valuable information that could be applied to other woody trees. Please find us on social media!
