Through successful identification of mechanisms and molecular characterisation of resistance to Peronospora parasitica races and the identification of sources of host resistance against these races, breeders, for the first time, will be able to develop cultivars with resistance against the full spectrum of P. parasitica races occurring across southern Australia. Benefits include prevention of severe losses in canola from downy mildew, and more viable and sustainable production with less reliance upon fungicides. This research addresses the National Research Priority 'An Environmentally Sustainable Australia' and the Priority Goal of 'Transforming existing industries', and will particularly benefit southern Australian rural communities.Read moreRead less
Race status, resistance mechanisms, and new sources of resistance to Phytophthora clandestina, a major threat to subterranean clover production. Devastating outbreaks of disease caused by Phytophthora clandestina (Phytophthora root rot) since the late 1970s demonstrated the capacity of this disease to impact severely on clover pasture production across southern Australia, particularly as new races of Phytophthora have rapidly emerged to overcome the resistance of all commercial cultivars. The p ....Race status, resistance mechanisms, and new sources of resistance to Phytophthora clandestina, a major threat to subterranean clover production. Devastating outbreaks of disease caused by Phytophthora clandestina (Phytophthora root rot) since the late 1970s demonstrated the capacity of this disease to impact severely on clover pasture production across southern Australia, particularly as new races of Phytophthora have rapidly emerged to overcome the resistance of all commercial cultivars. The proposed research seeks to delineate new races of the pathogen, to identify the histological and biochemical mechanisms by which resistance to Phytophthora root rot is expressed, and to identify new sources of host resistance. This proposed research will enable breeders, for the first time, to incorporate multiple types of resistance and against different races into new host varieties.Read moreRead less

Better bees for tomorrow: A proteomic and physiological characterization of male fertility in managed versus feral honeybees in Western Australia. The importance of honeybees for food production is often undervalued as they pollinate more than 80 crops of economic interest. However, honeybee populations are on a worldwide decline and the beekeepers struggle to survive economically. Australia has so far been spared of major collapses but this seems merely a question of time. The work proposed ini ....Better bees for tomorrow: A proteomic and physiological characterization of male fertility in managed versus feral honeybees in Western Australia. The importance of honeybees for food production is often undervalued as they pollinate more than 80 crops of economic interest. However, honeybee populations are on a worldwide decline and the beekeepers struggle to survive economically. Australia has so far been spared of major collapses but this seems merely a question of time. The work proposed initiates a close collaboration between the only honeybee-breeding organization in Western Australia and the University of Western Australia. Scientific research to ensure a future supply of managed and healthy honeybees is initiated to understand honeybee reproduction, diseases and immunity in more detail. The results are expected to be of interest for the entire Australian honeybee industry.Read moreRead less
