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
Explaining the interactions between drought and fertiliser use efficiency using tracing and imaging techniques. With climate change, Australian agriculture is faced with periods of increasing drought and changing rainfall patterns. At the same time, Australian farmers are faced with increasing costs of fertiliser inputs (their largest variable input cost), yet have little information on how they should change their nutrient management programs to suit the changing climatic conditions. This proje ....Explaining the interactions between drought and fertiliser use efficiency using tracing and imaging techniques. With climate change, Australian agriculture is faced with periods of increasing drought and changing rainfall patterns. At the same time, Australian farmers are faced with increasing costs of fertiliser inputs (their largest variable input cost), yet have little information on how they should change their nutrient management programs to suit the changing climatic conditions. This project aims to determine the effect of drought and rainfall patterns on the efficiency of fertiliser use by crops, through examination of the effects of soil moisture conditions on the interaction between soil and added fertilisers.

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
