Investigating a new paradigm for plant-pathogen interactions; Identification of host-selective toxin proteins in the wheat pathogen Stagonospora nodorum. Stagonospora nodorum is a fungus that causes leaf and glume blotch disease on wheat. This disease alone causes $55 million dollars in yield losses per annum. Traditional breeding methods have yielded crops that are only mildly resistant leaving control of the disease to be worryingly reliant on fungicides. This project aims to identify and char ....Investigating a new paradigm for plant-pathogen interactions; Identification of host-selective toxin proteins in the wheat pathogen Stagonospora nodorum. Stagonospora nodorum is a fungus that causes leaf and glume blotch disease on wheat. This disease alone causes $55 million dollars in yield losses per annum. Traditional breeding methods have yielded crops that are only mildly resistant leaving control of the disease to be worryingly reliant on fungicides. This project aims to identify and characterise proteins that the fungus secretes to cause disease on wheat. By identifying these proteins, it is anticipated that strategies, both traditional and modern, could be employed to enable better control of the disease. This in turn would help provide a long term and secure supply of wheat and wheat based products to the community.Read moreRead less
Comparative toxicology of a fumigant and gasotransmitters: Testing a new model of fumigant toxicity in Caenorhabditis elegans. Fumigants share physical, chemical and functional properties with a medically important class of signalling molecules called gasotransmitters. This project proposes that the toxicity of fumigants is directly caused by their ability to mimic and disrupt gasotransmitter signalling. This project will test this hypothesis using the fumigant phosphine, a chemical that protect ....Comparative toxicology of a fumigant and gasotransmitters: Testing a new model of fumigant toxicity in Caenorhabditis elegans. Fumigants share physical, chemical and functional properties with a medically important class of signalling molecules called gasotransmitters. This project proposes that the toxicity of fumigants is directly caused by their ability to mimic and disrupt gasotransmitter signalling. This project will test this hypothesis using the fumigant phosphine, a chemical that protects the vast majority of the world grain supply from insect pests. This work will show us what makes a fumigant toxic. This knowledge will facilitate the discovery and effective deployment of new fumigants.Read moreRead less
Mechanistic characterisation of genotype x environment interactions in sorghum and arabidopsis. Sorghum is an economically important cereal crop for Australia. In Australia, sorghum is used as a staple animal feed and it is very important for the live stock industry. With the predicted changes of temperature and rainfall patterns due to climate change, negative effects on sorghum yield are expected, which can have adverse effects on Australian economy. Our studies will identify and mark genes th ....Mechanistic characterisation of genotype x environment interactions in sorghum and arabidopsis. Sorghum is an economically important cereal crop for Australia. In Australia, sorghum is used as a staple animal feed and it is very important for the live stock industry. With the predicted changes of temperature and rainfall patterns due to climate change, negative effects on sorghum yield are expected, which can have adverse effects on Australian economy. Our studies will identify and mark genes that regulate flowering and seed production in sorghum in response to changes in temperature and light interactions. These studies will help to develop novel sorghum varieties with desirable characters through plant-breeding programmes.Read moreRead less
Ion transporters regulating plant adaptive responses to salinity and the modes of their control by compatible solutes in plant cells. Plants respond to saline conditions by a significant elevation in the level of compatible solutes in the cytosol. It appears that these solutes are not directly involved in conventional osmoprotection, but instead have a regulatory role in cell metabolism. This project will apply a range of state-of-the-art biophysical and molecular techniques to investigate the m ....Ion transporters regulating plant adaptive responses to salinity and the modes of their control by compatible solutes in plant cells. Plants respond to saline conditions by a significant elevation in the level of compatible solutes in the cytosol. It appears that these solutes are not directly involved in conventional osmoprotection, but instead have a regulatory role in cell metabolism. This project will apply a range of state-of-the-art biophysical and molecular techniques to investigate the modes of control exercised by compatible solutes over the activity of major plasma membrane transporters involved in plant adaptive responses to salinity. The work will substantially advance our understanding of salt tolerance and will provide a sound basis for genetic engineering of salt tolerant crops.Read moreRead less
