Improving neuronal cell function with cell permeable copper complexes. Metal-based drugs offer an exciting new approach to treatment of neurodegeneration. However, little is known about how cells metabolise these drugs and this information is critical for further drug development. This project will determine how metal-based drugs are metabolised by neuronal cells and how this may result in therapeutic benefit.
The global history of organic farming. The first global history of the organic farming movement explains how organic farming changed land-use, government policy and consumer habits. Understanding how this scientific and cultural movement arose, where it succeeded and where it failed, helps to better formulate policy that promotes sustainable agriculture, human health and climate.
Probing the four photosynthetic membrane protein complexes at work in situ in leaves. This proposal aims at sustainable improvements in plant productivity and photosynthetic adaptation in drastic Australian climates. In photosynthesis, membranes with the four multiprotein complexes use sunlight to make compounds that drive carbon assimilation. Instead of the usual dissection of photosynthetic membranes, this project will develop and refine the applicant's rapid, reliable, non-intrusive technique ....Probing the four photosynthetic membrane protein complexes at work in situ in leaves. This proposal aims at sustainable improvements in plant productivity and photosynthetic adaptation in drastic Australian climates. In photosynthesis, membranes with the four multiprotein complexes use sunlight to make compounds that drive carbon assimilation. Instead of the usual dissection of photosynthetic membranes, this project will develop and refine the applicant's rapid, reliable, non-intrusive techniques to probe the four membrane complexes at work in their native state in leaves. Two portable commercial instruments will potentially emerge from the techniques. This novel non-reductionist approach will identify key limitations to photosynthetic performance under stress, and insights into improvements for primary plant productivity.Read moreRead less
Transistor-based sensor technology for fast, reliable and accurate in situ monitoring of recycled wastewater. Water recycling is becoming critical for water supplies worldwide, due to declining natural supplies of fresh water, combined with increasing demand. The greatest community and industry concerns over recycled water are quality assurance and relative cost. Ensuring quality requires monitoring of contaminants, yet no single real-time technology exists to measure the myriad of potential con ....Transistor-based sensor technology for fast, reliable and accurate in situ monitoring of recycled wastewater. Water recycling is becoming critical for water supplies worldwide, due to declining natural supplies of fresh water, combined with increasing demand. The greatest community and industry concerns over recycled water are quality assurance and relative cost. Ensuring quality requires monitoring of contaminants, yet no single real-time technology exists to measure the myriad of potential contaminants. This project will develop technology using AlGaN/GaN-based transistors, sensitised to different contaminants, enabling multi-analyte real-time sensor arrays. In situ monitoring systems based on such arrays will be fast, accurate, reliable, low-cost, and applicable to a broad variety of water recycling projects.Read moreRead less
The cellulose synthase complex of the Arabidopsis primary cell wall. The polysaccharide cellulose is the basis for the wood and cotton fibre industries of Australia and much of our research on the mechanism of synthesis has been supported by those industries over the past decade. The present project focuses on the proteins making cellulose and how they organised into functional complexes that are able to make cellulose. The knowledge it provides, together with that from other projects, will move ....The cellulose synthase complex of the Arabidopsis primary cell wall. The polysaccharide cellulose is the basis for the wood and cotton fibre industries of Australia and much of our research on the mechanism of synthesis has been supported by those industries over the past decade. The present project focuses on the proteins making cellulose and how they organised into functional complexes that are able to make cellulose. The knowledge it provides, together with that from other projects, will move us towards the situation where we can manipulate the rate at which cellulose is produced and change its detailed properties. This opens the way to industry producing fibres with more desirable properties and producing novel cellulose-based materials tailored to specific applications.Read moreRead less
Functional Genomic Analysis of Exported DNAJ Molecules in the Malaria Parasite Plasmodium falciparum. Malaria is not only a global health problem, but also affects countries surrounding Australia like PNG and Indonesia, reducing the region's stability and prosperity. Environmental changes and increased mobility of people (eg. aid and security personnel) make Australia itself more prone to malaria. The project will translate recent genomic data into functional insights using frontier technology t ....Functional Genomic Analysis of Exported DNAJ Molecules in the Malaria Parasite Plasmodium falciparum. Malaria is not only a global health problem, but also affects countries surrounding Australia like PNG and Indonesia, reducing the region's stability and prosperity. Environmental changes and increased mobility of people (eg. aid and security personnel) make Australia itself more prone to malaria. The project will translate recent genomic data into functional insights using frontier technology to identify new intervention targets for P. falciparum infection. Developing novel targets is mandated by humanity, and also to safeguard Australia's region against the social and economical implication of this disease. An Australian developed intervention would increase the global visibility of its science, leading to increased investments.Read moreRead less

Understanding how plants generate the huge diversity of shapes seen in nature is both a scientific challenge and a biotechnological opportunity. Microtubules dominate cell architecture, providing dynamic, yet rigid, frameworks for defining or changing growth polarity. We recently discovered and cloned MOR1, a gene that is essential for organizing microtubules and controlling morphogenesis. This places us in a strong position to resolve a long-standing mystery: how are microtubules organized? We intend to define MOR1's structural attributes, identify its interacting proteins and innovate an ambitious screen for additional genes that have related functions. This project should stimulate new ideas and applications.Read moreRead less

The possibility of manipulating a single molecule seems at first unreal, indeed 5 years ago it was pure science fiction. Through the gaining popularity of the Atomic Force Microscope (AFM) many perspectives about the molecular world are changing. Macroscopic effects such as adhesion and lubrication are now discussed in light of measurements made with this instrument. Newer work includes the observation of single protein unfolding experiments. The biophysics oriented project detailed in this application will extend the AFM: into multi-molecular systems formed by self-assembly, such as cell membranes; into polyelectrolyte-surface interactions; and, finally into the sequencing of DNA.Read moreRead less
