Genome-wide association analysis identifies a consistent QTL for powdery mildew resistance on chromosome 3A in Nordic and Baltic spring wheat.

QPm.NOBAL-3A is an important QTL providing robust adult plant powdery mildew resistance in Nordic and Baltic spring wheat, aiding sustainable crop protection and breeding. Powdery mildew, caused by the biotrophic fungal pathogen Blumeria graminis f.

The Role of Exopolysaccharides in Plant-Pathogen Interactions.

The phytopathogenic bacterium (), one of the members of the soft rot , forms biofilm-like structures known as bacterial emboli when colonizing the primary xylem vessels of the host plants. The initial extracellular matrix of the bacterial emboli is composed of the host plant's pectic polysaccharides, which are gradually substituted by the -produced exopolysaccharides ( EPS) as the bacterial emboli "mature". No information about the properties of EPS and their possible roles in -plant interactions has so far been obtained.

The Modification of Plant Cell Wall Polysaccharides in Potato Plants during -Caused Infection.

Our study is the first to consider the changes in the entire set of matrix plant cell wall (PCW) polysaccharides in the course of a plant infectious disease. We compared the molecular weight distribution, monosaccharide content, and the epitope distribution of pectic compounds and cross-linking glycans in non-infected potato plants and plants infected with at the initial and advanced stages of plant colonization by the pathogen. To predict the gene products involved in the modification of the PCW polysaccharide skeleton during the infection, the expression profiles of potato and PCW-related genes were analyzed by RNA-Seq along with phylogenetic analysis.

Genome-Wide Association Analysis and Genomic Prediction for Adult-Plant Resistance to Septoria Tritici Blotch and Powdery Mildew in Winter Wheat.

Septoria tritici blotch (STB) caused by the fungal pathogen and powdery mildew (PM) caused by f.sp () are among the forefront foliar diseases of wheat that lead to a significant loss of grain yield and quality. Resistance breeding aimed at developing varieties with inherent resistance to STB and PM diseases has been the most sustainable and environment-friendly approach.
