The Role of Root Exudates of Barley Colonized by in Enhancing Root Colonization by .

The aim of this study was to find out why after joint inoculation of the substrate with the phytopathogenic fungus and the antagonistic bacterium the amount of the fungus on the root surface in the beginning of the colonization was greater on the roots colonized by the bacterium than on control roots. This phenomenon is especially interesting because joint inoculation with was always followed by a considerable decrease in the incidence of Fusarium root rot. In two experiments barley was grown in sterile vermiculite inoculated only with , only with and jointly with the fungus and the bacterium.

Receptor-Like Kinase LYK9 in Pisum sativum L. Is the CERK1-Like Receptor that Controls Both Plant Immunity and AM Symbiosis Development.

Plants are able to discriminate and respond to structurally related chitooligosaccharide (CO) signals from pathogenic and symbiotic fungi. In model plants and LysM-receptor like kinases (LysM-RLK) AtCERK1 and OsCERK1 (chitin elicitor receptor kinase 1) were shown to be involved in response to CO signals. Based on phylogenetic analysis, the pea L.

Molecular and immunochemical phylogeny of Verticillium species.

21 strains with all typical morphological characteristics of eight Verticillium species (Phyllachorales) were studied in this work, together with representatives from four Hypocreales species (11 strains), that were previously classified as members of the genus. The PCR products from two nuclear genes, i.e.
