We have discovered natural products with biological activity in plants and mammals. These molecules affect plant shape and development and the process of mammalian blood vessel formation. We seek to understand how these molecules work. More understanding is required before one can begin to utilise these molecules for possible beneficial agriculture or human health outcomes. Plant shape influences such things as yield or more drought-resilient root systems. Importantly, we have discovered specific molecules that either promote or inhibit blood vessel formation. A better understanding of how these molecules work could lead to novel treatments for cancer or cardiovascular disease.Read moreRead less

Chromatin structure and pervasive transcription. This project aims to understand mechanisms that repress pervasive transcription and to identify chromatin characteristics that repress transcription initiation outside the promoter regions. Chromatin characteristics, such as position, occupancy and turnover-rate of nucleosomes, establish an elaborate genomic indexing mechanism, which defines functional units in the genome. Defects in this process increase pervasive transcription, toxic accumulatio ....Chromatin structure and pervasive transcription. This project aims to understand mechanisms that repress pervasive transcription and to identify chromatin characteristics that repress transcription initiation outside the promoter regions. Chromatin characteristics, such as position, occupancy and turnover-rate of nucleosomes, establish an elaborate genomic indexing mechanism, which defines functional units in the genome. Defects in this process increase pervasive transcription, toxic accumulation of non-coding transcripts and genomic instability. This work aims to understand eukaryotic genome organisation and may have long-term therapeutic implications for cancer and ageing-related diseases.Read moreRead less

The ecological dynamics of secreted bacteriocins and the evolution of multiple bacteriocin production in Escherichia coli. Bacteria produce compounds known as bacteriocins that are toxic to other microorganisms. The success of bacteria as bio-control agents and in probiotic formulations for the control microbial pathogens is, in part, due to bacteriocins. Bacteriocins may also have a role as replacements for traditional antibiotics and as natural food preservatives. The potential usefulness of b ....The ecological dynamics of secreted bacteriocins and the evolution of multiple bacteriocin production in Escherichia coli. Bacteria produce compounds known as bacteriocins that are toxic to other microorganisms. The success of bacteria as bio-control agents and in probiotic formulations for the control microbial pathogens is, in part, due to bacteriocins. Bacteriocins may also have a role as replacements for traditional antibiotics and as natural food preservatives. The potential usefulness of bacteriocins as the active agent in bio-control agents, as antibiotic replacements, as food preservatives, and as part of the repertoire of traits in probiotic formulations requires a sound understanding of the eco-evolutionary dynamics of bacteriocins. Understanding the ecology and evolution of bacteriocins is the goal of the proposed research.Read moreRead less

In Australia, Ross River virus (RRV) represents significant concern to human health. Between 1992-2005 more than 50,000 notifications of RRV infection have been reported. While not fatal, the disease is responsible for morbidity in the community/individual that can have both social and economic costs. The project has several national benefits. It will help elucidate whether there is any association between RRV strain and increased risk of RRV transmission and/or occurrence of more severe cases of human disease. It will help develop technologies that can lead towards the identification of viral markers, which could provide new avenues in the design of novel antiviral strategies.
