Role of alanine aminotransferase in improved nitrogen use efficiency (NUE) in cereals. The use of nitrogen-based fertilisers by crop plants is poor where efficiencies (nitrogen taken up to that applied) is often less than 40%. Nitrogen not used is often lost to the environment through leaching and or volatilisation. Improving nitrogen use efficiency (NUE) in agriculture will decrease overall nitrogen fertiliser use and minimise its environmental footprint. This project will characterise a nov ....Role of alanine aminotransferase in improved nitrogen use efficiency (NUE) in cereals. The use of nitrogen-based fertilisers by crop plants is poor where efficiencies (nitrogen taken up to that applied) is often less than 40%. Nitrogen not used is often lost to the environment through leaching and or volatilisation. Improving nitrogen use efficiency (NUE) in agriculture will decrease overall nitrogen fertiliser use and minimise its environmental footprint. This project will characterise a novel NUE technology that when transferred to plants significantly improves NUE. We will define the phenotype at the molecular, biochemical and physiological levels to maximise its adoption to other agricultural crops such as wheat, barley and maize.Read moreRead less
IMPROVING NITROGEN USE EFFICIENCY IN CROP PLANTS: ROLE OF THE AMMONIUM TRANSPORT FAMILY AMT. Improving nitrogen use efficiency in crop plants will reduce the use of environmentally damaging nitrogen fertilisers that threaten through leaching the sustainability of Australia's agricultural sector and local water ecosystems.

We will identify the in planta activity of the A ....IMPROVING NITROGEN USE EFFICIENCY IN CROP PLANTS: ROLE OF THE AMMONIUM TRANSPORT FAMILY AMT. Improving nitrogen use efficiency in crop plants will reduce the use of environmentally damaging nitrogen fertilisers that threaten through leaching the sustainability of Australia's agricultural sector and local water ecosystems. Plants contain genes that encode transport proteins required for the uptake of nitrogen (ammonium and nitrate) from the soil. We will identify the in planta activity of the AMT family of ammonium transporters and associated signalling pathways which control the uptake and assimilation of ammonium in plants. This project will confirm the mechanisms involved in ammonium uptake from the soil and lead to the development of ammonium-nitrogen efficient crop plants.Read moreRead less
Salinity tolerance and long-distance transport in cereals. The aim of this program is to alter shoot accumulation of solutes in cereals by exploiting novel transgenic technology to manipulate processes in specific cell types in the roots. The primary objective is the generation of cereals which have increased tolerance of saline soils. This is clearly of much agricultural significance in Australia. More general outcomes include the generation of plants with altered concentrations of a range of n ....Salinity tolerance and long-distance transport in cereals. The aim of this program is to alter shoot accumulation of solutes in cereals by exploiting novel transgenic technology to manipulate processes in specific cell types in the roots. The primary objective is the generation of cereals which have increased tolerance of saline soils. This is clearly of much agricultural significance in Australia. More general outcomes include the generation of plants with altered concentrations of a range of nutrients in both leaves and grain. This will be of wide agricultural and nutritional benefit, as well as providing an understanding of principles underlying the long-distance co-ordination of processes in plants.Read moreRead less
Targeted approaches to improve nitrogen use efficiency in maize. Nitrogen is an essential input required for growing high yielding quality cereal crops such as maize and wheat. Unfortunately, excessive use of nitrogen fertilizers can lead to serious environmental costs including nitrogen pollution through leaching and the significant cost in non-renewable fossil fuels used in their production. Improving nitrogen use efficiency in crops such as maize will reduce fertilizer use while ensuring lo ....Targeted approaches to improve nitrogen use efficiency in maize. Nitrogen is an essential input required for growing high yielding quality cereal crops such as maize and wheat. Unfortunately, excessive use of nitrogen fertilizers can lead to serious environmental costs including nitrogen pollution through leaching and the significant cost in non-renewable fossil fuels used in their production. Improving nitrogen use efficiency in crops such as maize will reduce fertilizer use while ensuring long-term sustainable production and harvestable yields. This collaboration with DuPont-Pioneer will focus on identifying nitrogen-linked traits in Maize that will be incorporated into new lines targeted at reducing grower dependence on nitrogen fertilizers.Read moreRead less
Improving nitrogen use efficiency in crop plants: Functional analysis of high-affinity ammonium transport in plant lines altered in ammonium transport capacity. Improving nitrogen fertiliser use in crop species will benefit Australia and world agriculture by reducing nitrogen-linked environmental pollution. Nitrogen fertilisers can be leached from soils and result in the pollution of ground water, rivers, estuaries and oceans. Using model plant systems we are dissecting the genes and their encod ....Improving nitrogen use efficiency in crop plants: Functional analysis of high-affinity ammonium transport in plant lines altered in ammonium transport capacity. Improving nitrogen fertiliser use in crop species will benefit Australia and world agriculture by reducing nitrogen-linked environmental pollution. Nitrogen fertilisers can be leached from soils and result in the pollution of ground water, rivers, estuaries and oceans. Using model plant systems we are dissecting the genes and their encoded proteins responsible for ammonium nitrogen uptake into plants. Identifying the in planta function of these genes will allow new breeding approaches to specifically target genes that will improve the efficiency of ammonium uptake and lessen the reliance on the supply of nitrogen fertilizers in modern agricultural crop production.Read moreRead less

The project is part of a new paradigm for agriculture in which staple crops are bred with greater micronutrient density to improve human health. It generates strategic basic information on how nutrients interact in the body of animal models in absorption, transport and utilisation that will allow plant breeders to optimise the breeding strategy for maximum outcomes in health and minimum breeding cost. Animals deficient in the nutrients of most concern (iron, zinc, vitamin A - and inulin) will be fed new varieties with enhanced levels of these factors, and from the responses, a superior strategy will be developed.Read moreRead less

The Australian Agrifood sector will benefit significantly from the establishment of functional genomics platform technologies, such as metabolomics, that underpin 'Systems Biology'; a new branch of biology that attempts to discover and understand biological properties that emerge from the interactions of many system elements. Australian agriculture will benefit through the development of techniques to improve both yield and quality through minimising the effects of abiotic and biotic stresses, and a reduced dependence on inputs (eg fertilisers) leading to environmentally sustainable production systems. Ultimately this will result in enhanced food quality and analytical methods to monitor quality and safety characteristics of food.Read moreRead less
