This project will devise nucleic acid and serology methods for detection of Olpidium brassicae, vector of lettuce big-vein disease (LBVD), during various phases of lettuce seedling production in nursery environments. It will be the first study to develop sustainable and environmentally responsible nursery best-practice protocols for integrated management of O. brassicae in routine seedling production and for management within the lettuce industry. These protocols will ensure that the spread of LBVD from contaminated lettuce nurseries to farms is prevented. It will also be a unique study of the establishment of a disease in new land with different soils and agricultural practices.Read moreRead less
Race status, sources of resistance and mechanisms of resistance to Peronospora parasitica, a major threat to oilseed Brassica production in Australia.

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

Provision of larval culture diets that provide optimal nutrition in a suitable presentation format is the major challenge for developing a rock lobster aquaculture industry. Tropical rock lobsters are likely contenders due to their faster growth rates and shorter larval phase than temperate species. This project will assess the ingestive and digestive capabilities of larvae during development, through an examination of mouthpart and gut structure and their types and concentration of digestive enzymes. Information will be used to formulate and test improved diets of appropriate size, texture and nutritional composition and will be the first comprehensive analysis of preferred larval diets on the basis of their biological and physiological characteristics.Read moreRead less

This project aims to identify the proteins produced by Stagonospora nodorum through the development of a new proteomics technique. Two clear benefits to the community resulting from this project will emerge. The first will be the expert training of a student in proteomics, a skill that is keenly sought. Secondly, the identification of these pathogen proteins will lead to new strategies to better control the disease and secure the supply of wheat.Read moreRead less
Accelerating the genetic improvement of grain legumes for Australia by developing doubled haploid technology for field pea and chickpea. Doubled haploid technology is used in many broad acre crop species to accelerate cultivar development and create homozygous populations for genetic mapping. Field pea and chickpea have been unresponsive to this technique but a recent breakthrough by UWA researchers has resulted in haploid pro-embryos from in vitro cultured immature pollen. A barrier to further ....Accelerating the genetic improvement of grain legumes for Australia by developing doubled haploid technology for field pea and chickpea. Doubled haploid technology is used in many broad acre crop species to accelerate cultivar development and create homozygous populations for genetic mapping. Field pea and chickpea have been unresponsive to this technique but a recent breakthrough by UWA researchers has resulted in haploid pro-embryos from in vitro cultured immature pollen. A barrier to further embryo maturation has been identified, which we propose to overcome using powerful microscopy tools to elucidate haploid embryology processes. This information will be applied to develop world-first in vitro doubled haploid protocols for these species, which will facilitate the development and accelerated delivery to industry of better adapted, high yielding cultivars.Read moreRead less
