Controlling accumulation of elements in the shoots of higher plants by manipulating processes in specific cell types in the roots. This project will provide novel, fundamental understanding of the processes controlling accumulation of elements in the shoots of plants. As such, it will impact on our understanding of processes relevant to stress tolerance, plant nutrition, human nutrition and the removal of toxic metals from soils by plants. These are all areas of great importance to Australian ag ....Controlling accumulation of elements in the shoots of higher plants by manipulating processes in specific cell types in the roots. This project will provide novel, fundamental understanding of the processes controlling accumulation of elements in the shoots of plants. As such, it will impact on our understanding of processes relevant to stress tolerance, plant nutrition, human nutrition and the removal of toxic metals from soils by plants. These are all areas of great importance to Australian agriculture, environmental sustainability and human health. The increased understanding arising from this project will underpin future work to increase agricultural productivity and the quality of life for all in the Australian and international communities.Read moreRead less
Development of advanced screening protocols for the identification of genes involved in nutrient sensing and nutrient efficiency in plants. Sustainable plant production in Australia builds on the concept of stable crop yield and high crop quality at low pesticide and fertilizer input. This requires a more efficient use of the plant's own mechanisms to efficiently explore nutrient patches in soils that are usually heterogeneously distributed. The identification of nutrient sensors in plants will ....Development of advanced screening protocols for the identification of genes involved in nutrient sensing and nutrient efficiency in plants. Sustainable plant production in Australia builds on the concept of stable crop yield and high crop quality at low pesticide and fertilizer input. This requires a more efficient use of the plant's own mechanisms to efficiently explore nutrient patches in soils that are usually heterogeneously distributed. The identification of nutrient sensors in plants will not only allow a deeper understanding of how plants manage to overcome nutrient-poor growth periods but also open new possibilities for enhancing nutrient efficiency in crop plants. The increased understanding arising from this project will underpin future work to increase agricultural productivity and the quality of life for all in the Australian and international communities.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
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

Control points in nitrogen uptake: enhancing the response of cereals to nitrogen supply and demand. Vast amounts of nitrogen fertiliser are applied to cereal crops to maintain yields. By uncovering what limits nitrogen uptake in cereals, this project will provide the scientific basis for improving nitrogen use efficiency and decreasing fertiliser use, with significant economic and environmental benefits.
