▪ Abstract Interspecific hybridization can disrupt normal resistance of plant and animal
species to their parasites. Resistance to parasites is affected by hybridization in the following …

Our understanding of the molecular basis of plant-pathogen interactions is derived mostly
from studies of model annual plant species, and until recently, few addressed disease …

Phenolic secondary metabolites are often thought to protect plants against attack by
microbes, but their role in defense against pathogen infection in woody plants has not been …

Nonpathogenic foliar fungi (ie endophytes and epiphytes) can modify plant disease severity
in controlled experiments. However, experiments have not been combined with ecological …

The transcriptional response of hybrid poplar (Populus trichocarpa× P. deltoids) to poplar
leaf rust (Melampsora medusae) infection was studied using the Populus 15.5 K cDNA …

The species of the genus Populus, collectively known as poplars, are widely distributed over
the northern hemisphere and well known for their ecological, economical, and evolutionary …

Stomata are essential for diffusive entry of gases to support photosynthesis, but may also
expose internal leaf tissues to pathogens. To uncover trade‐offs in range‐wide adaptation …

A cDNA clone of a wheat germin-like oxalate oxidase (OxO) gene regulated by the
constitutive CaMV 35S promoter was expressed in a hybrid poplar clone, Populus× …

Hybrids of Melampsora medusae and M. occidentalis are herein described as M.×
columbiana. This hybrid taxon is characterized by isolates that generally exhibit …

Foliar endophytes of Populus do not induce the hypersensitive response associated with
major genes for resistance to Melampsora leaf rust. But they could contribute to the …
