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
Plasmid maintenance and interactions with the host cell and its genome. Plasmids are extrachromosomal genetic elements that play a central role in the evolution of bacteria. They are the most dynamic component of the bacterial genome, augmenting the host chromosome by conferring a range of significant phenotypes that facilitate environmental adaptation. This project aims to elucidate fundamental aspects of the relationship between plasmids and their bacterial hosts. Significant outcomes include ....Plasmid maintenance and interactions with the host cell and its genome. Plasmids are extrachromosomal genetic elements that play a central role in the evolution of bacteria. They are the most dynamic component of the bacterial genome, augmenting the host chromosome by conferring a range of significant phenotypes that facilitate environmental adaptation. This project aims to elucidate fundamental aspects of the relationship between plasmids and their bacterial hosts. Significant outcomes include understanding the molecular basis of efficient plasmid inheritance in bacterial populations, and exploration of the innovative hypothesis that plasmids modulate expression of the host chromosome, a possibility that would profoundly alter our view of how plasmids influence host phenotype.Read moreRead less
Bacterial Cell Division: Discovering how it begins and the network of protein interactions it requires. All cells must coordinate cell division with chromosome replication to ensure that the DNA is partitioned equally into newborn cells. We will establish the defect of a novel mutant blocked in the earliest stage of cell division in bacteria to obtain unique information about this vital regulatory step. We will use our newly discovered protein interaction network to establish what role protein i ....Bacterial Cell Division: Discovering how it begins and the network of protein interactions it requires. All cells must coordinate cell division with chromosome replication to ensure that the DNA is partitioned equally into newborn cells. We will establish the defect of a novel mutant blocked in the earliest stage of cell division in bacteria to obtain unique information about this vital regulatory step. We will use our newly discovered protein interaction network to establish what role protein interactions play in integrating cell division with other biological pathways in the cell to ensure its tight regulation. Our discoveries will facilitate the design of new antibiotics that target cell division to fight antibiotic-resistant bacteria and bioterrorism organisms.Read moreRead less
Investigating the Ability of Honey to Inhibit Bacterial Biofilms Found in Chronic Wounds. Chronic (non-healing) wounds are a serious health problem in Australia. One quarter of our institutionalized aged population have pressure ulcers. The difficulty in treating these wounds is that most contain communities of bacteria, called biofilms, that are not killed by conventional antibiotics. Special honeys from Australia and NZ that are effective in chronic wound treatment can eradicate these biofilms ....Investigating the Ability of Honey to Inhibit Bacterial Biofilms Found in Chronic Wounds. Chronic (non-healing) wounds are a serious health problem in Australia. One quarter of our institutionalized aged population have pressure ulcers. The difficulty in treating these wounds is that most contain communities of bacteria, called biofilms, that are not killed by conventional antibiotics. Special honeys from Australia and NZ that are effective in chronic wound treatment can eradicate these biofilms. This project will identify the components in honey that do this and determine how they do it, to provide a more effective chronic wound treatment. It will decrease the prevalence of these wounds in Australia and the associated personal trauma and health costs.Read moreRead less
Establishing how bacterial cells position the division site. Cell division is essential for life. It is required for bacterial infections and, if uncontrolled, causes diseases such as cancer. We will establish how bacterial cells position the division site precisely to ensure faithful production of newborn cells. We will use the latest technology in bacterial cell biology to provide novel, clear-cut information to maintain Australia at the leading edge of this important area of research.

We will establish how bacterial cells position the division site precisely to ensure faithful production of newborn cells. We will use the latest technology in bacterial cell biology to provide novel, clear-cut information to maintain Australia at the leading edge of this important area of research. There is an alarming increase in antibiotic resistant bacteria and an imminent threat of bioterrorism. This research allows the opportunity for the development of new antibiotics to protect Australia protected from these dangerous bacteria. Read moreRead less
Regulating the earliest step in bacterial cell division: Z ring assembly. Cell division is essential for survival. What are the cues that signal cells to divide at the right place and at the right time? How do cells ensure that when division occurs to produce two newborn cells, each one receives the correct amount of DNA? The answers to these questions are essential to understand how organisms reproduce and grow. But they remain unknown. This research addresses these questions in bacteria. Our d ....Regulating the earliest step in bacterial cell division: Z ring assembly. Cell division is essential for survival.

How do cells ensure that when division occurs to produce two newborn cells, each one receives the correct amount of DNA? The answers to these questions are essential to understand how organisms reproduce and grow. But they remain unknown. This research addresses these questions in bacteria. Our discoveries will have a significant impact on our understanding of the regulation of this vital process and will facilitate the design of novel antibiotics that target it.Read moreRead less
Conservation genetics of humpback whales off Western Australia: Implications for the management of the Antarctic Group IV population. We will define the geographic structuring and gene flow of humpback whales comprising Antarctic Area Group IV, and which migrate off the coast of Western Australian. With this information we will develop guidelines for commonwealth, state, industry, and non-government organisations, for conserving and managing discrete (genetic) populations of humpback whales off ....Conservation genetics of humpback whales off Western Australia: Implications for the management of the Antarctic Group IV population. We will define the geographic structuring and gene flow of humpback whales comprising Antarctic Area Group IV, and which migrate off the coast of Western Australian. With this information we will develop guidelines for commonwealth, state, industry, and non-government organisations, for conserving and managing discrete (genetic) populations of humpback whales off Western Australia. We can then manage these cetaceans at the appropriate geographic scale, and assign conservation priority in relation to population genetic structure gained from this study.Read moreRead less
Simulating viral evolution and genetic complexity. This project has direct relevance to understanding the growth of viral infections, and therefore has possible practical applications in disease research and control. Examples of these are emerging diseases in humans such as those caused by HIV-1, SARS coronavirus and Dengue virus, which cause considerable human suffering throughout the world.

This project has direct relevance to understanding the growth of viral infections, and therefore has possible practical applications in disease research and control. Examples of these are emerging diseases in humans such as those caused by HIV-1, SARS coronavirus and Dengue virus, which cause considerable human suffering throughout the world. A major part of current research into these diseases involves attempts to model the evolutionary genetics and dynamics of virus populations in order to understand how to control epidemics, develop vaccines and design drugs. The research program is designed to provide new computational modelling tools for this purpose, which may have wider applications as well.

Molecular genetic analyses of trinucleotide repeat expansions. Several neuronal diseases like Huntington's disease, Frederick's ataxia and fragile X syndrome are caused by expansion of trinucleotide repeat sequences in the deoxyribonucleic acid (DNA). These diseases show progressive severity in subsequent generations. Here we use a simple plant model with a very similar DNA mutation to study the genetic basis of repeat expansions over several generations across populations. This proposal will im ....Molecular genetic analyses of trinucleotide repeat expansions. Several neuronal diseases like Huntington's disease, Frederick's ataxia and fragile X syndrome are caused by expansion of trinucleotide repeat sequences in the deoxyribonucleic acid (DNA). These diseases show progressive severity in subsequent generations. Here we use a simple plant model with a very similar DNA mutation to study the genetic basis of repeat expansions over several generations across populations. This proposal will improve our mechanistic understanding of genetic diseases in populations. In addition, this proposal is expected to lead to identification of potential targets and technologies that would be of interest to Australian industry.Read moreRead less
