To understand key processes governing defense mechanisms in poplar (Populus spp.) upon infection with the rust fungus Melampsora larici-populina, we used combined histological and molecular techniques to describe the infection of Populus trichocarpa x Populus deltoides 'Beaupré' leaves by compatible and incompatible fungal strains. Striking differences in host-tissue infection were observed aft...
Uredinia of poplar leaf rust, Melampsora medusae Thüm f.sp. deltoides, appeared in late July 1998, June 1999, and August 2000 in a cottonwood (Populus deltoides Bartr.) stand in Ames, Iowa. Seedlings of the alternate host (eastern larch, Larix laricina (Du Roi) K. Koch) set out at the site in spring 2000 formed aecia 3 months before uredinia appeared. Using three PCR-based microsatellite marker...
Abstract. Most trees emit volatile organic compounds (VOCs) continuously throughout their life, but the rate of emission and spectrum emitted VOCs become substantially altered when experience stress. Despite this, models to predict emissions do not account for perturbations caused by biotic plant Considering that such stresses have generally been forecast increase in both frequency severity fut...
