Preparatory processes in rapid interceptive action. This project investigates the nature of the processes involved in preparing to act in response to a moving object: actions that elite sportspeople perform with amazing precision: timing to within a few thousandths of a second is routine when hitting a ball in tennis and cricket. The average person can be capable of something similar and it means being ready to make the right movement at the right time.

This project investigates the nature of the processes involved in preparing to act in response to a moving object: actions that elite sportspeople perform with amazing precision: timing to within a few thousandths of a second is routine when hitting a ball in tennis and cricket. The average person can be capable of something similar and it means being ready to make the right movement at the right time. Understanding the preparatory processes involved will be a significant scientific advance and knowledge of their workings and limits can contribute to the development of strategies for improving safety in dynamic environments such as city roads. This project will put an Australian laboratory at the cutting edge in this area of research.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
Insect host/vector genetic responses to rhabdovirus infection. Rhabdoviruses cause important diseases in humans, animals and plants. These viruses are transmitted by insect vectors in which they persist and propagate, an intimate and specific association. Insect-rhabdovirus interactions will be studied at the molecular level using a planthopper-maize rhabdovirus model. Insect genes specifically induced by rhabdovirus infection as well as the viral genes themselves will be identified and characte ....Insect host/vector genetic responses to rhabdovirus infection. Rhabdoviruses cause important diseases in humans, animals and plants. These viruses are transmitted by insect vectors in which they persist and propagate, an intimate and specific association. Insect-rhabdovirus interactions will be studied at the molecular level using a planthopper-maize rhabdovirus model. Insect genes specifically induced by rhabdovirus infection as well as the viral genes themselves will be identified and characterized using genomics and bioinformatics tools. We will extend the same approaches to a comparative analysis of these planthopper genes with other insect-rhabdovirus systems under investigation in our institutes. Identification of viral genes expressed in insects, the insect genes that respond to virus infection, and interpretation of the roles of these genes in insects, may indicate new opportunities to control serious plant and animal diseases through control of virus transmission.Read moreRead less

Molecular Cell Biology and Comparative Genomics Of Planctomycetes and Verrucomicrobia In Relation To Evolution Of Cytoskeletal Proteins and Membrane-bounded Compartments. 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.

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

Understanding an exotic disease: Initiation of sex and infection by the sugarcane smut Ustilago scitaminea. Australian sugar exports generate almost $2 billion in annual sales, making the sugar industry a critical facet of the Australian economy.

Australian sugar exports generate almost $2 billion in annual sales, making the sugar industry a critical facet of the Australian economy. In 2006, Australia's primary sugar producing region came under threat when an outbreak of sugarcane smut caused by the fungus Ustilago scitaminea first appeared in Queensland. Management of this potentially devastating disease has focused on breeding programmes aimed at developing resistant sugarcane cultivars, a complex process hampered by a lack of information about the mechanisms of smut resistance. Our research will provide key insight into the mechanisms by which U. scitaminea infects sugarcane, directing future breeding efforts and protecting this valuable industry against further outbreaks.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
