This project will investigate plant responses to soil microbes in the model legume, Medicago truncatula, to provide fundamental information needed to design crops with improved abilities to interact beneficially with soil microbes. Plant development and performance are significantly influenced by soil microbes, but it is largely unknown how the information contained in microbial signalling molecules is relayed to plants. Proteome analysis and immunocytochemistry will be combined to identify and localise differentially expressed proteins in roots treated with specific microbial signal molecules. Annotated Proteome databases will be generated to strengthen and complement an international project on M. truncatula genome analysis.Read moreRead less
Does a novel class of small RNA molecules control self-incompatibility in solanaceous plants? Self-incompatibility is a simple and genetically defined cell recognition system that prevents inbreeding in many plant species. Flowers of self-incompatible plants can distinguish self pollen from foreign pollen, and allow only foreign pollen to fertilise their egg cells. This proposal will investigate the possibility that the part of the genetic self-incompatibility locus controlling recognition of ....Does a novel class of small RNA molecules control self-incompatibility in solanaceous plants? Self-incompatibility is a simple and genetically defined cell recognition system that prevents inbreeding in many plant species. Flowers of self-incompatible plants can distinguish self pollen from foreign pollen, and allow only foreign pollen to fertilise their egg cells. This proposal will investigate the possibility that the part of the genetic self-incompatibility locus controlling recognition of pollen is a novel type of gene that encodes a small RNA molecule but no protein. Knowledge gained by studying the self-incompatibility genes will help us to understand how plant cells recognise each other, and may allow us to manipulate seed (and hence crop) production.Read moreRead less
Adaptations of plant mitochondria during cold acclimation in Arabidopsis thaliana: towards an understanding of plant cold acclimation. Frost damage is a major cost to agricultural producers and some crop plant species needlessly adapt to cold, when they are grown in temperate regions or in glasshouses, which leads to decreased production. The principal outcome of this project will be to greatly extend our knowledge about plant mitochondrial responses to environmental cold stress and what role th ....Adaptations of plant mitochondria during cold acclimation in Arabidopsis thaliana: towards an understanding of plant cold acclimation. Frost damage is a major cost to agricultural producers and some crop plant species needlessly adapt to cold, when they are grown in temperate regions or in glasshouses, which leads to decreased production. The principal outcome of this project will be to greatly extend our knowledge about plant mitochondrial responses to environmental cold stress and what role they have in helping plants adapt to environmental change. An understanding of cold acclimation may allow the production of plants with altered cold acclimation phenotypes and greater frost tolerance.Read moreRead less
The Cytochrome P450 Gene Super-family in Drosophila melanogaster; Gene Function and Insecticide Resistance. The cytochrome P450 (Cyp) gene super-family is represented by over 90 sequences in the genome of the vinegar fly, Drosophila melanogaster. To date, four Cyp genes are found to be involved in insecticide resistance. The function of the majority of Cyp genes is unknown. This project will investigate the function and regulation of D. melanogaster Cyp genes, linking the fly's genotype to its ....The Cytochrome P450 Gene Super-family in Drosophila melanogaster; Gene Function and Insecticide Resistance. The cytochrome P450 (Cyp) gene super-family is represented by over 90 sequences in the genome of the vinegar fly, Drosophila melanogaster. To date, four Cyp genes are found to be involved in insecticide resistance. The function of the majority of Cyp genes is unknown. This project will investigate the function and regulation of D. melanogaster Cyp genes, linking the fly's genotype to its phenotype. By studying the effects of Cyp genes on fly survival, Cyp gene expression and regulation, and expressing selected Cyp genes in a yeast expression system, we will enhance our understanding of Cyp gene function and evolution.Read moreRead less
Molecular basis of the interaction between plant disease resistance proteins and pathogen avirulence proteins. Management of crop diseases involves the integrated use of resistant cultivars and the application of chemical pesticides.

Management of crop diseases involves the integrated use of resistant cultivars and the application of chemical pesticides. Many diseases, however, including rust, continue to pose an economically significant threat to agricultural productivity in Australia. The research outlined in this proposal aims to understand the mechanisms, at a molecular and structural level, that enable resistant plants to detect and respond to pathogen attack. The outcomes of this currently unavailable fundamental understanding will enable new, durable and more effective resistance genes to be engineered. Therefore, the work has significant economic and environmental implications for agricultural crop plant productivity in this country.Read moreRead less
Understanding the molecular basis of marine invertebrate larval settlement and metamorphosis using complementary molecular, developmental, chemical and ecological approaches.

The colonisation and fouling of submerged structures is a major economic problem for maritime industries. This proposal will detail the molecular mechanisms underlying the first crucial steps of marine invertebrate colonisation - settlement and metamorphosis - and determine how natural anti-foulant chemicals impact on these developmental processes. By using complementary developmental, molecular, chemical and ecological approaches, we will obtain knowledge of key control points in settlement and metamorphosis, and thus identify potential pest management strategies. This proposal comprehensively delineates the role of novel anti-foulants, linking their effect on invertebrate development with their role in shaping marine communities on natural and built surfaces.Read moreRead less
Preparatory processes in rapid interceptive action. This project investigates the nature of the processes involved in preparing to act in response to a moving object: actions that elite sportspeople perform with amazing precision: timing to within a few thousandths of a second is routine when hitting a ball in tennis and cricket. The average person can be capable of something similar and it means being ready to make the right movement at the right time. Understanding the preparatory processes in ....Preparatory processes in rapid interceptive action. This project investigates the nature of the processes involved in preparing to act in response to a moving object: actions that elite sportspeople perform with amazing precision: timing to within a few thousandths of a second is routine when hitting a ball in tennis and cricket. The average person can be capable of something similar and it means being ready to make the right movement at the right time. Understanding the preparatory processes involved will be a significant scientific advance and knowledge of their workings and limits can contribute to the development of strategies for improving safety in dynamic environments such as city roads. This project will put an Australian laboratory at the cutting edge in this area of research.Read moreRead less
Dissecting a hematopietic transcription factor complex. The development of mature active cells is a highly complex and coordinated process that is controlled largely by groups of interacting regulatory proteins. We are trying to understand, at a very detailed level, how a specific group of these proteins interact to regulate both normal blood cell development and the onset of childhood leukemias. Using this information we will try to develop reagents that can be used to inhibit these interaction ....Dissecting a hematopietic transcription factor complex.
