Efficient organelle transformation. Chloroplasts and mitochondria are the powerhouses of plant and animal cells. Ability to express introduced genes in these organelles has enormous biotechnological potential in agriculture and medicine, but practical development has been almost stalled for 15 years by very low transformation efficiency. Plastid transformation is today routine only in tobacco; and mitochondrial transformation has been achieved only in yeasts and algae.

Ability to express introduced genes in these organelles has enormous biotechnological potential in agriculture and medicine, but practical development has been almost stalled for 15 years by very low transformation efficiency. Plastid transformation is today routine only in tobacco; and mitochondrial transformation has been achieved only in yeasts and algae. We have developed a solution, and achieved the key technical requirements for proof of concept. This collaboration between industry, government and university partners will deliver key Australian-owned IP, for environmentally-friendly plant biofactories, and for treatment of mitochondrial genetic disorders.Read moreRead less

Real time PCR and nanoparticle diagnostic facilities for high-throughput quantitative analysis of genomic structure and gene expression. Modern molecular tools have lead to an explosion in genome projects and unification of all areas of biology. The most basic need for such research is access to improving technologies for detecting DNA fingerprints that distinguish genetically-diverse genes, and determining which genes are "switched on" or 'off' in various situations.

Modern molecular tools have lead to an explosion in genome projects and unification of all areas of biology. The most basic need for such research is access to improving technologies for detecting DNA fingerprints that distinguish genetically-diverse genes, and determining which genes are "switched on" or 'off' in various situations. Real time PCR technology, pioneered by The University of Queensland (UQ) and Southern Cross University (SCU) using ARC funding in 1996, is now the technology of choice for much of this research. This project will provide high-throughput equipment for real time PCR, and will develop complementary high-throughput "nanoparticle" DNA genotyping technologies, with applications to medicine and agriculture.

Control of Wolbachia replication: maintaining a stable symbiosis. This project will use a comparative genomics approach to better understand how Wolbachia infections of insects are able to maintain themselves in insects without causing pathology. The results will allow us to better understand a distinguishing characteristic of an intracellular symbiont, namely replication control. The results also have the potential to lead to new approaches to insect pest control through a better understanding ....Control of Wolbachia replication: maintaining a stable symbiosis.

The results also have the potential to lead to new approaches to insect pest control through a better understanding of how Wolbachia might be used to skew insect population age structure.Read moreRead less
A New Window into Transgene Silencing in Plants: mechanisms of copy-number independent, 5' sequence dependent, post-transcriptional silencing in a complex polyploid. Silencing of introduced genes is a major problem limiting plant molecular improvement. Sugarcane, a complex polyploid, shows the most efficient transgene silencing ever observed in plants. Silencing operates on the RNA, depends on the upstream sequence of the gene, and is independent of copy number. Other plant species develop endop ....A New Window into Transgene Silencing in Plants: mechanisms of copy-number independent, 5' sequence dependent, post-transcriptional silencing in a complex polyploid. Silencing of introduced genes is a major problem limiting plant molecular improvement. Sugarcane, a complex polyploid, shows the most efficient transgene silencing ever observed in plants. Silencing operates on the RNA, depends on the upstream sequence of the gene, and is independent of copy number. Other plant species develop endopolyploidy with age, and show unpredictable or patchy silencing. We speculate that differential silencing is a natural control mechanism in the exploitation of polyploidy in plants. The sugarcane system provides an exceptional opportunity to identify the sequences that trigger and protect from silencing, and to develop approaches to avoid the problem.Read moreRead less
Phasevarions of Haemophilus influenzae: mechanisms and origins of a novel epigenetic system controlling coordinated random switching in expression of multiple genes. Central to the utilisation of biological information is our ability to identify and interpret DNA sequence information from genomes. In bacteria that cause disease, these investigations can identify key aspects of the infectious process or potential components of vaccines or new targets for antibiotics. Our recent work has identifie ....Phasevarions of Haemophilus influenzae: mechanisms and origins of a novel epigenetic system controlling coordinated random switching in expression of multiple genes. Central to the utilisation of biological information is our ability to identify and interpret DNA sequence information from genomes. In bacteria that cause disease, these investigations can identify key aspects of the infectious process or potential components of vaccines or new targets for antibiotics. Our recent work has identified a new genetic system, the 'phasevarion', that mediates random expression of multiple genes. The proposed research aims to advance our understanding of gene expression at the most basic level, revealing how bacteria generate diverse populations to evade environmental and immune stresses, and facilitating improved interpretation and use of DNA sequences for researchers and industry in this field.Read moreRead less

Planctomycetes and verrucomicrobia are evolutionarily distinct groups of bacteria which possess unusual cell structure and which share some significant genes important in cell biology with eukaryotes e.g. in verrucomicrobia the cytoskeleton protein tubulin. These bacteria are important for understanding the transition from non-nucleated cells with simple cell division to nucleated cells with chromosome separation via cytoskeletal protein movement.The project will compare genomes of of planctomycetes and verrucomicrobia to determine their relationship, determine whether the tubulin homolog of verrucomicrobia can form cytoskeleton structures, and characterize the cytoskeleton of ammonium-oxidizing planctomycetes used in wastewater treatment.Read moreRead less
Novel vaccines and serotyping scheme for Haemophilus parasuis. Glasser's disease, caused by the bacterium Haemophilus parasuis, is a significant problem in Australian and overseas pig industries. Current approaches to the management of Glassers disease utilise antibacterials and also vaccines. However, antibacterials are of limited effectiveness in juvenile pigs (weaners) that are difficult to medicate other than by injection, and current vaccines are only protective against the serotypes incl ....Novel vaccines and serotyping scheme for Haemophilus parasuis. Glasser's disease, caused by the bacterium Haemophilus parasuis, is a significant problem in Australian and overseas pig industries. Current approaches to the management of Glassers disease utilise antibacterials and also vaccines. However, antibacterials are of limited effectiveness in juvenile pigs (weaners) that are difficult to medicate other than by injection, and current vaccines are only protective against the serotypes included in the vaccine. We propose to examine the immune response to natural infection and identify potential vaccine candidates which will then be tested in vaccine trials. The APAI will focus on developing a DNA-based typing scheme for H. parasuis.Read moreRead less

Our aim is to set up a world-class facility for proteomics research which will allow a large cohort of scientists at several institutions to identify individual proteins in vanishingly small samples of very complex mixtures. This facility will enable investigation of the control of gene expression, the intricate organisation of proteins within cells, and proteins which are potential drug targets. This equipment is an essential resource for Queensland research groups.Read moreRead less
