Identification, modification and deployment of genetic factors controlling resistance to important pathogens in barley. Subproject A (IdeMoDeResBar)
Project
Project code: 031B0199A
Contract period: 01.11.2016
- 31.10.2019
Budget: 188,149 Euro
Purpose of research: Applied research
IdeMoDeResBar aims at the isolation of major genes and Quantitative trait loci involved in the resistance against barley yellow mosaic virus disease (BaMMV/BaYMV), leaf rust (Puccinia hordei), net blotch (Pyrenophora teres) and scald (Rhynchosporium commune). Furthermore, it aims at editing two already isolated genes against barley yellow mosaic virus disease. This will on the one hand lead to a deeper understanding of the structure and function of resistance genes and will on the other hand contribute to a more directed use of genetic resources as a prerequisite for breeding resistant cultivars followed by their use in consumer and environmental friendly barley production systems.
The project is structured in four working packages, i.e. (i) fine and physical mapping of targeted resistance loci and identification of candidate genes, (ii) bioinformatic analyses and data integration, (iii) functional analysis of candidate genes and genome engineering of two virus resistance genes against barley yellow mosaic virus disease, and (iv) marker assisted backcrossing and use of novel resistance genes in hybrid breeding. For gene isolation Genotyping by sequencing (GBS) and Renseq will be conducted and genomic resources, e.g. available ExomeCapture data and the barley reference sequence, will be employed. For the functional analysis of candidate genes and the in planta generation of resistance alleles in elite material we will use an established platform of RNA-guided CAS nucleases. Respective resistance genes will be transferred to adapted breeding lines by marker assisted backcrossing and in a next step used for hybrid breeding.
