What defines sperm success? The influence of sperm on storage and paternity success in the honeybee Apis mellifera. The honeybee is a species of economic interest and becomes increasingly important for crop pollination, especially in areas where naturally occurring pollinating insects are declining. However, the bee industry struggles to breed sufficient numbers of bees, as climatic changes, parasites and pesticides can kill large numbers of bee hives. Breeding success in honeybees crucially dep ....What defines sperm success? The influence of sperm on storage and paternity success in the honeybee Apis mellifera. The honeybee is a species of economic interest and becomes increasingly important for crop pollination, especially in areas where naturally occurring pollinating insects are declining. However, the bee industry struggles to breed sufficient numbers of bees, as climatic changes, parasites and pesticides can kill large numbers of bee hives. Breeding success in honeybees crucially depends on queens receiving sufficient numbers of viable sperm. The study of honeybee sperm and its possible interactions with the queen can therefore optimize breeding regimes for example by providing ways to estimate male or sperm quality.Read moreRead less
A multidisciplinary research program to assess limiting factors and predict impacts of climate change for endangered Australian orchids. Climate change poses a significant threat to biodiversity. Australian sexually deceptive orchids are dependent on obligate and specialised interactions with pollinators and fungi. Consequently, they may face a high risk of extinction if climate change uncouples these interactions. Thus orchids provide an important bio-indicator of change. The tools and expertis ....A multidisciplinary research program to assess limiting factors and predict impacts of climate change for endangered Australian orchids. Climate change poses a significant threat to biodiversity. Australian sexually deceptive orchids are dependent on obligate and specialised interactions with pollinators and fungi. Consequently, they may face a high risk of extinction if climate change uncouples these interactions. Thus orchids provide an important bio-indicator of change. The tools and expertise developed will contribute directly to the conservation of endangered Australian orchids, and will take into account the risks of climate change. The project will contribute to the priority research goals of sustainable use of Australia's biodiversity as well as responding to climate change and variability. The project will also provide high quality, cross-disciplinary training.Read moreRead less
Mammalian histidine kinase: its characterisation and role in hepatic cellular proliferation. Protein kinases regulate all aspects of cellular metabolism, but there is a class of protein kinase, histidine kinases, which exists in mammalian cells, about which remarkably little is understood. This project will be the first detailed characterisation of such an enzyme and investigation of its cellular function. The enzyme to be characterised is hepatic and it has been implicated in the regulation of ....Mammalian histidine kinase: its characterisation and role in hepatic cellular proliferation. Protein kinases regulate all aspects of cellular metabolism, but there is a class of protein kinase, histidine kinases, which exists in mammalian cells, about which remarkably little is understood. This project will be the first detailed characterisation of such an enzyme and investigation of its cellular function. The enzyme to be characterised is hepatic and it has been implicated in the regulation of DNA replication in regenerating liver. We shall obtain a detailed picture of the role of this histidine kinase in liver cell biology and an insight into the more general biological role of this class of enzyme.Read moreRead less

State-of-the-art biophysical tools for the characterisation of molecular interactions. In the current era of 'the genome' there is more demand than ever before for the characterisation of the gene products - the oligonucleotides and proteins that carry out the important functions in the cell. The current proposal is to acquire a suite of instrumentation to characterise the kinetics, thermodynamics and overall affinities of interactions between biological macromolecules and their physiological bi ....State-of-the-art biophysical tools for the characterisation of molecular interactions. In the current era of 'the genome' there is more demand than ever before for the characterisation of the gene products - the oligonucleotides and proteins that carry out the important functions in the cell. The current proposal is to acquire a suite of instrumentation to characterise the kinetics, thermodynamics and overall affinities of interactions between biological macromolecules and their physiological binding partners or with novel ligands. This will reveal the role of the macromolecules of interest in the cell, and potentially lead to the discovery of drug molecules which could interfere with molecular interactions underlying disease.Read moreRead less
Targeting mitochondrial dysfunction in disease. Defects in mitochondria, the energy producing compartments within cells, lead to severe neurodegenerative diseases and contribute to the development of cancer. Treatment for such diseases caused by mutations in mitochondrial DNA remains unsatisfactory and mostly confined to supportive measures. The identification of proteins that regulate gene expression within mitochondria provides an unexplored resource of potential disease modulators and drug ta ....Targeting mitochondrial dysfunction in disease. Defects in mitochondria, the energy producing compartments within cells, lead to severe neurodegenerative diseases and contribute to the development of cancer. Treatment for such diseases caused by mutations in mitochondrial DNA remains unsatisfactory and mostly confined to supportive measures. The identification of proteins that regulate gene expression within mitochondria provides an unexplored resource of potential disease modulators and drug targets. This research will lead to new strategies in the design of improved anticancer drugs, which is an important Australian research priority that will promote and maintain good health, and provide potential commercial outcomes.Read moreRead less
Molecular machines: regulation of the catalysis and rotation of the enzyme ATP synthase. This project aims to elucidate the regulation of the molecular machine ATP synthase. ATP synthase is an enzyme that performs a critical role in all cells - the synthesis of ATP, the universal biological energy currency. It is known that the enzyme operates via rotation of a central stalk which is driven by a hydrogen ion gradient across a membrane.

This project aims to elucidate the regulation of the molecular machine ATP synthase. ATP synthase is an enzyme that performs a critical role in all cells - the synthesis of ATP, the universal biological energy currency. It is known that the enzyme operates via rotation of a central stalk which is driven by a hydrogen ion gradient across a membrane. Constructs of this molecule have been envisaged in the design of future biological nano-motors. Our work will provide an understanding of the regulation of this enzyme with potential application in the control of nano-motors.Read moreRead less

Sex, Sperm and Society. Insights into the evolutionary potential of sexual conflict in insects: a fundamental question in evolutionary biology.

Insights into the evolutionary potential of sexual conflict in insects: a fundamental question in evolutionary biology. Social insects are biologically and economically important species. Honeybees or stingless bees are used for crop pollination and honey production and invasive ants or termites are severe pest species causing economic damage. Part of the biological success of social insects is based on the capability to produce colonies with many workers although colonies typically contain only one or very few reproductives. Consequently, colony success is bound to queen fertility and studying social insect reproduction can therefore optimize breeding regimes of species of interest or offer new possibilities to control pest species. Detailed information on sperm form and function will provide pioneering insights into the complexity of sexual reproduction.Read moreRead less
