Regulation and expression of disease resistance responses in the Rhynchosporium secalis/barley interaction. The barley leaf scald fungus, Rhynchosporium secalis, causes annual losses of up to 10% in Australia's major export crop, barley. The primary aim of this project is to isolate and understand the interplay of genes specifically involved in the regulation of resistance to scald. Several resistance-specific genes will be functionally analysed to identify regulatory signalling pathways that li ....Regulation and expression of disease resistance responses in the Rhynchosporium secalis/barley interaction. The barley leaf scald fungus, Rhynchosporium secalis, causes annual losses of up to 10% in Australia's major export crop, barley. The primary aim of this project is to isolate and understand the interplay of genes specifically involved in the regulation of resistance to scald. Several resistance-specific genes will be functionally analysed to identify regulatory signalling pathways that link genetic expression with the specific gene-for-gene disease resistance phenotype. Knowledge of the genes controlling signalling processes within the disease-challenged plant will allow for the development of more effective and durable resistances by traditional breeding and transgenic approaches.Read moreRead less
