Abstract The native vs. exotic status of reed canarygrass (RCG), a major invasive species Minnesota wetlands, is unknown. aim this study was to investigate enhance its management. Genetic comparison wild RCG populations from six and Czech Republic rivers performed. A total 2521 polymorphic SNP markers (single nucleotide polymorphisms) were used evaluate 478 samples across all collections. In th...

The relationship of peroxidases to an inducible disease-resistance mechanism involving lignification of leaf epidermal cell walls was studied. Reed canarygrass (Phalaris arundinacea L.) leaf discs were inoculated with Helminthosporium avenae Eidam and floated on water. In inoculated discs, the activity of soluble, ionic wall-bound and covalent wall-bound peroxidases was about twice the level of...

—Phalaris arundinacea L. (reed canarygrass) is an aggressive graminoid species that invades wetlands in much of the northern United States. In areas previously used for agriculture and other recently disturbed habitats, P. arundinacea out-competes the native flora and creates monocultures, which reduce biodiversity and alter ecosystem functioning. Much research has focused on the growth respons...
