The proposed research will lead to advances in understanding the regulation of plant development, a process impacting on agriculture, environmental management and human health, areas designated as national research priorities. This understanding is required for modifying plant growth and architecture to fit particular environments, for example generating plants with more extensive and deeper roots to mine the soil moisture and nutrients to enhance crop productivity in Australia, and maintaining the competitive advantage of Australian agriculture in view of the range of environmental conditions encountered in this country. The project will also contribute to the health of the Australian population through consumable plants in the diet.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

Hybrid economic futures for remote Indigenous Australia: Linking poverty reduction and natural resource management. In the 21st century the Indigenous population of sparsely-settled Australia will increase rapidly. This population has historically experienced extremely low socioeconomic status. With land rights and native title, a significant ecologically intact estate, now over 20 percent of Australia, is under Indigenous ownership. This research will explore how enhanced Indigenous involvement ....Hybrid economic futures for remote Indigenous Australia: Linking poverty reduction and natural resource management. In the 21st century the Indigenous population of sparsely-settled Australia will increase rapidly. This population has historically experienced extremely low socioeconomic status. With land rights and native title, a significant ecologically intact estate, now over 20 percent of Australia, is under Indigenous ownership. This research will explore how enhanced Indigenous involvement in customary (non market) activities, natural and cultural resource management, and new industries can generate economic and social benefits for remote Indigenous communities that lack access to the market. National benefits will be generated from enhanced biodiversity conservation, and from cost savings associated with improved socio-economic status.Read moreRead less

For example, we are evolving enzymes to better degrade organophosphate pesticides that are environmental pollutants. Apart from producing useful enzymes, the proposed research aims at gaining a better understanding of how enzymes work and how they evolve. We intend to determine the structure of many related enzymes that have been evolved to have enhanced activities. This data will be used to analyze the intricate relationship between sequence, structure and enzyme activity.Read moreRead less
THE MECHANISMS OF PHOTOPROTECTION IN PLANTS - A GENOMICS AND PHOTOPHYSICAL APPROACH. Coping with adverse environmental conditions is central to plant survival in nature so understanding the photoprotective mechanisms of light acclimation is important for crop improvement. Therefore, effective acclimatory mechanisms at whole plant, cellular and molecular levels are essential to accommodate short and long-term exposure to potentially photodamaging full sunlight and environmental stresses, such as ....THE MECHANISMS OF PHOTOPROTECTION IN PLANTS - A GENOMICS AND PHOTOPHYSICAL APPROACH. Coping with adverse environmental conditions is central to plant survival in nature so understanding the photoprotective mechanisms of light acclimation is important for crop improvement. Therefore, effective acclimatory mechanisms at whole plant, cellular and molecular levels are essential to accommodate short and long-term exposure to potentially photodamaging full sunlight and environmental stresses, such as drought and temperature extremes that lead to plant death or greatly reduced crop yields due to free radical damage. This project brings together a unique cross-disciplinary expertise in biophysics, biochemistry, physiology and genomics to elucidate the known mechanisms and identify unknown factors in photoprotection.Read moreRead less
Reduced Water Consumption in Commercial Malting Processes. The successful outcome for the project will be the production of barley varieties that can be successfully malted with a single steep, rather than the conventional two steeps currently employed. The objective will be achieved through the reduction of cell wall beta-glucan in barley grain. This will result in water savings of around 40%, or 1,500 megalitres per annum, for the Australian malting industry. The 1,500 megalitres saving in ....Reduced Water Consumption in Commercial Malting Processes.

This will result in water savings of around 40%, or 1,500 megalitres per annum, for the Australian malting industry. The 1,500 megalitres saving in water use would be sufficient to support the domestic water consumption of 30,000 people, based upon the use of 140 litres per person per day that was recently achieved in Brisbane.Read moreRead less
The contribution of beneficial arbuscular mycorrhizal (AM) fungi to sustainable tomato production in Australia. Formation of beneficial arbuscular mycorrhiza (AM) by processing tomatoes has been used as an indicator of 'healthy soil' in an environmental monitoring audit of the industry in southern Australia, but field occurrence of the AM fungi and their potential contribution to tomato nutrition and productivity are not well understood.

Formation of beneficial arbuscular mycorrhiza (AM) by processing tomatoes has been used as an indicator of 'healthy soil' in an environmental monitoring audit of the industry in southern Australia, but field occurrence of the AM fungi and their potential contribution to tomato nutrition and productivity are not well understood. We will determine the responsiveness of widely-grown tomato varieties to AM inoculation and relate colonisation in the field to farming practices. The results will determine the potential benefits of AM fungi to tomato crops, in the context of development of environmentally and economically sustainable practices both in Australia and overseas.

Environmental risk assessment of acid sulfate soil formation and pollutant generation in Swan Coastal Plain. The urgency and importance of securing water sources for human use in a sustainable manner is dictated by drying climate and rapid population expansion in Australia. Dropping groundwater levels (less recharge, increased abstraction, enhanced drainage) result in formation of acid sulfate soils in oxidised layers that contain acid-bearing minerals. This project will produce an environmental ....Environmental risk assessment of acid sulfate soil formation and pollutant generation in Swan Coastal Plain. The urgency and importance of securing water sources for human use in a sustainable manner is dictated by drying climate and rapid population expansion in Australia. Dropping groundwater levels (less recharge, increased abstraction, enhanced drainage) result in formation of acid sulfate soils in oxidised layers that contain acid-bearing minerals. This project will produce an environmental risk assessment framework as a basis for (i) educated decisions regarding land development and soil disturbance vs conservation as well as (ii) identifying areas suitable for water abstraction from groundwater resources. This will ensure sustainable use of precious groundwater resources in this drying continent of ours.Read moreRead less
