Host-Induced Gene Silencing in Black Cottonwood for Control of Septoria Canker: Efficacy and Non-Target Impacts

Creator:: Gordon, Michael I.
Abstract:: Septoria canker remains the most important disease of poplars in intensively managed forest plantations. Genetic resistance has long been considered the best way to manage for this disease. Transgenic resistance mediated by RNA silencing against pathogens and pests (HIGS: host-induced gene silencing) has shown promise in other pathosystems but has...
