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

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

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
Purification and bioactivity of legume protein as nutritional supplements . Lupin seed is a major Australian high protein legume crop, undervalued at only ~$200 tonne due to its use as an animal feed. However this project aims to add value to the crop by designing a scalable food-grade and commercialisable technology to purify the protein gamma-conglutin from lupin seed waste as a nutraceutical for human blood glucose control.

Lupin seed is a major Australian high protein legume crop, undervalued at only ~$200 tonne due to its use as an animal feed. However this project aims to add value to the crop by designing a scalable food-grade and commercialisable technology to purify the protein gamma-conglutin from lupin seed waste as a nutraceutical for human blood glucose control. The process optimisation and mechanism of action for gamma-conglutin will be informed by proteomic analysis and cellular studies. From the project farmers may benefit through adding a premium to their crop value, a new gamma-conglutin purification technology will be available for processors to commercialise and consumers will have a natural product to help their blood glucose control.Read moreRead less

Genome editing to improve the dietary quality of potato. The project aims to develop non-genetically modified (non-GM) potato varieties with lower glycaemic index (GI) but good agronomic and culinary traits. Potato is the world's fourth-most important food. It is integral to the western diet and consumption is rising rapidly in Asia. However, the starch in cooked potato is readily digestible causing a rapid elevation of blood sugar levels on eating (i.e. it has a high GI). Long-term consumption ....Genome editing to improve the dietary quality of potato. The project aims to develop non-genetically modified (non-GM) potato varieties with lower glycaemic index (GI) but good agronomic and culinary traits. Potato is the world's fourth-most important food. It is integral to the western diet and consumption is rising rapidly in Asia. However, the starch in cooked potato is readily digestible causing a rapid elevation of blood sugar levels on eating (i.e. it has a high GI). Long-term consumption of meals with high GI is associated with increased risk of obesity, type-2 diabetes and cardiovascular disease. This project aims to use new genome editing methods to silence key genes that influence starch composition and thus develop non-GM potato varieties with lower GI to reduce these risks.Read moreRead less

Weeds and increasingly herbicide resistant weeds are the major yield penalty for agriculture. This project aims to develop innovative ways to overcome resistance. This project expects to (i) make herbicides work more efficiently, (ii) reveal a new mode of action for an under-used herbicide and (iii) assign breakdown pathways to herbicides. Expected outcomes of this project are to (i) to find rare, but truly synergistic herbicide combinations; (ii) reveal a herbicide against which weeds outside of Japan have not evolved resistance to; and (iii) establish how best to make breakdown blockers. A benefit of using existing herbicides is the approaches are close to market, so with partner Nexgen Plants, its outcomes can be commercialised.Read moreRead less
