Are flavonoids metabolic regulators of plant development? This project will investigate the mechanisms of action of flavonoids, which are abundant and diverse plant products contained in all fruits and vegetables. We have very little knowledge on the range of activities this large class of natural compounds has in plants. This research will investigate the role of flavonoids in regulating plant development to identify flavonoids and their target proteins and genes that could alter plant develo ....Are flavonoids metabolic regulators of plant development? This project will investigate the mechanisms of action of flavonoids, which are abundant and diverse plant products contained in all fruits and vegetables. We have very little knowledge on the range of activities this large class of natural compounds has in plants. This research will investigate the role of flavonoids in regulating plant development to identify flavonoids and their target proteins and genes that could alter plant development in specific ways to create improved crops. This project will also strengthen Australia's expertise in proteomics, an important tool for the advancement of knowledge and application in biotechnology.Read moreRead less
Connecting soil nitrogen and plant uptake for greener agriculture. This project will use synthetic organic chemistry, biochemistry, root and rhizosphere biology and rhizosphere modelling to establish detailed mechanistic knowledge of the nitrogen (N) transport and uptake processes at the soil-root interface to develop new, efficient urease and nitrification inhibitors for reliable provision of N to the plant/root system. The reduction of excessive N fertilisation has significant environmental be ....Connecting soil nitrogen and plant uptake for greener agriculture. This project will use synthetic organic chemistry, biochemistry, root and rhizosphere biology and rhizosphere modelling to establish detailed mechanistic knowledge of the nitrogen (N) transport and uptake processes at the soil-root interface to develop new, efficient urease and nitrification inhibitors for reliable provision of N to the plant/root system. The reduction of excessive N fertilisation has significant environmental benefits by reducing greenhouse gas emissions and water pollution. This project will lead to a breakthrough for the triple challenge of food security, environmental degradation and climate change, while improving plant productivity and increasing the profitability of agriculture through lower fertiliser costs.Read moreRead less
Using the fractionation of hydrogen and carbon isotopes to analyse the mechanisms of the primary processes of photosynthesis. The primary processes of CO2 fixation and reduction in photosynthesis leave their signatures in the isotopic composition of organic matter. Although these signatures are used widely in geochemistry, biology and climatology to infer the dynamics and history of the biosphere, the information they provide about the mechanisms of the processes that produce them has not been e ....Using the fractionation of hydrogen and carbon isotopes to analyse the mechanisms of the primary processes of photosynthesis. The primary processes of CO2 fixation and reduction in photosynthesis leave their signatures in the isotopic composition of organic matter. Although these signatures are used widely in geochemistry, biology and climatology to infer the dynamics and history of the biosphere, the information they provide about the mechanisms of the processes that produce them has not been exploited fully. We propose to map the underlying biochemistry responsible for fractionation of hydrogen isotopes, to assess its ability to indicate the water relations of plants, and to use carbon-isotope discrimination to probe the catalytic chemistry of the CO2-fixing enzyme, Rubisco.Read moreRead less
