The role of the ammonium transport bHLHm1/AMF1 regulatory loci in plants. This project aims to investigate the role of a regulatory locus in the regulation of ammonium transport in plants and the interacting genetic and biochemical signalling promoting the interaction. Ammonium is an important nutrient source for plant growth and development. It has been recently identified that a new transport mechanism (AMF1 ) mediates ammonium transport across legume root nodule cellular membranes.

This project aims to investigate the role of a regulatory locus in the regulation of ammonium transport in plants and the interacting genetic and biochemical signalling promoting the interaction. Ammonium is an important nutrient source for plant growth and development. It has been recently identified that a new transport mechanism (AMF1 ) mediates ammonium transport across legume root nodule cellular membranes. AMF1 was identified through a transcriptional interaction with a membrane localised bHLHm1 transcription factor. Both bHLHm1 and AMF1 belong to a unique chromosomal regulatory locus common across sequenced dicot plant species.Read moreRead less
High temperature limits of leaf function. In arid and semi-arid central Australia, Acacia spp. dominate the over-storey, but this shifts to Eucalyptus and Corymbia spp. in more mesic coastal regions. Areas of central Australia are extremely hot, dry and sunny, and it is this combination of stresses that likely excludes Eucalyptus spp. from many landforms. There has been little research on high temperature tolerance of Acacia and Eucalyptus, despite the putative importance of this stress, in co ....High temperature limits of leaf function. In arid and semi-arid central Australia, Acacia spp. dominate the over-storey, but this shifts to Eucalyptus and Corymbia spp. in more mesic coastal regions. Areas of central Australia are extremely hot, dry and sunny, and it is this combination of stresses that likely excludes Eucalyptus spp. from many landforms. There has been little research on high temperature tolerance of Acacia and Eucalyptus, despite the putative importance of this stress, in combination with other stresses, in limiting species? distributions. Our program of collaborative research will examine the tolerance of Acacia and Eucalyptus to a combination of high temperatures, drought and high light.Read moreRead less
Symbiotic transport proteins in legumes. Some plants form a symbiosis with soil bacteria (rhizobia) that convert atmospheric nitrogen to ammonia which is then supplied to the plant. This enables legumes to grow without application of nitrogen-based fertilizer, avoiding environmental problems such as run-off and land degradation, thereby contributing to sustainable agriculture practise. We will investigate the interactions between plant and rhizobia, focusing on identifying genes and proteins wh ....Symbiotic transport proteins in legumes. Some plants form a symbiosis with soil bacteria (rhizobia) that convert atmospheric nitrogen to ammonia which is then supplied to the plant. This enables legumes to grow without application of nitrogen-based fertilizer, avoiding environmental problems such as run-off and land degradation, thereby contributing to sustainable agriculture practise. We will investigate the interactions between plant and rhizobia, focusing on identifying genes and proteins which govern nutrient exchange between the partners and development of the special structures in the roots that house the bacteria. Subsequent manipulation of these genes and proteins may allow us to identify control points and enhance nitrogen fixation.

Online dietary assessment for research: the Automated Self-Administered 24-Hour Dietary Recall System for Australia: This project brings together key researchers nationally in the field of nutrition and dietetics to develop a standardised, high quality, online system to assess food intake among adults across a variety of research settings and study designs. The proposed infrastructure is an Australian version of the Automated Self-Administered 24-Hour Dietary Recall (ASA24) in collaboration with the United States National Cancer Institute. The infrastructure is internationally renowned and will underpin research that builds the evidence-base for policies and programs in the field of nutrition and dietetics. Read moreRead less

This research hub aims to provide Australian growers and industrial stakeholders with improved plant materials to maximise production, environmental sustainability and profitability. In particular, the research aims to improve the nitrogen delivery capacity of legumes and their resilience to abiotic stress, which will be an important consideration as our climate changes. Grain legumes are often grown in rotation with cereal crops for their high nutritional seed value and their unique ability to develop a self-sufficient nitrogen-fixing symbiosis with soil bacteria. Maintaining legume productivity against the challenges of climate change and the need for increased food production is important to the future of Australian agriculture.Read moreRead less
Healthy eating campaigns: perceptions of the message and messenger. This project will be a means to evaluate the likely effectiveness of some of the resolutions of the NSW Childhood Obesity Summit aimed at the commercial food industry and the media.

This project will be a means to evaluate the likely effectiveness of some of the resolutions of the NSW Childhood Obesity Summit aimed at the commercial food industry and the media. The project will provide information for the food industry on consumers' perceptions of their credibility as a source of information about healthy eating. This will inform the development of communication campaigns, as well as provide guidance on development and marketing of 'healthier' brand extensions. The project will also have considerable benefit for public health. The findings will be relevant to government and non-government health promotion organisations considering the effectiveness of social marketing campaigns in association with food companies.Read moreRead less

Here we will increase the content and / or catalytic efficiency of the primary carboxylase of C4 photosynthesis (PEPC) that supplies CO2 to the carbon concentrating mechanism and ensures high photosynthetic rates. We will develop new SynBio tools to create and test novel PEPC isoforms with desirable properties. Ultimately, the project aims to identify isoforms that improve plant fitness under stress conditions. Optimising PEPC activity will provide next generation solutions to improve water balance and carbon assimilation to keep C4 crops productive under future climates.Read moreRead less
Reducing environmental footprint by improving phosphorous use efficiency.

While modern agriculture relies heavily on the use of phosphorous fertilizers, most of them are not used by plants and lost in runoff, resulting in a massive environmental damage through contamination of waterways (termed eutrophication). This project takes advantage of an untapped resource - a unique collection of Tibetan wild barley genotypes, to reveal key traits that confer superior phosphorus use efficiency in wild barley and identify appropriate candidate genes and their position on chromosomes for further incorporating these traits into commercial barley cultivars. This will reduce the environmental footprint of modern agricultural practices on terrestrial and aquatic ecosystems without compromising food security.Read moreRead less
