The evolutionary transition from anaerobic to aerobic metabolism. This project aims to find out how life on Earth survived the revolutionary changes when cyanobacteria first released oxygen into the atmosphere. These events led to a transition from anoxic (oxygen-free) to oxic (oxygen-rich) conditions. A comparative genomic view across a series of photosynthetic organisms will be performed at the molecular level with ecological interpretation. Understanding of what metabolic changes occurred in ....The evolutionary transition from anaerobic to aerobic metabolism. This project aims to find out how life on Earth survived the revolutionary changes when cyanobacteria first released oxygen into the atmosphere. These events led to a transition from anoxic (oxygen-free) to oxic (oxygen-rich) conditions. A comparative genomic view across a series of photosynthetic organisms will be performed at the molecular level with ecological interpretation. Understanding of what metabolic changes occurred in response to the shifts in the environment will have wide implications for predicting the evolutionary events that are still occurring today, such as rapidly changing climatic conditions. This fundamental research will enhance Australia's profile in this field.Read moreRead less
The link between environmental stress and disease onset in prawn aquaculture. The federal government has set a target for prawn aquaculture production to increase fourfold by 2010. A major barrier is disease: losses of 20% of production to viral diseases are not uncommon. To be internationally competitive, Australia needs to develop high health production systems. Most prawn stock carry chronic viral infections, but only exhibit disease symptoms following environmental stress. This project will ....The link between environmental stress and disease onset in prawn aquaculture. The federal government has set a target for prawn aquaculture production to increase fourfold by 2010. A major barrier is disease: losses of 20% of production to viral diseases are not uncommon. To be internationally competitive, Australia needs to develop high health production systems. Most prawn stock carry chronic viral infections, but only exhibit disease symptoms following environmental stress. This project will identify environmental stressors that activate viral disease in Penaeus monodon. Outcomes will be incorporated into on-farm managerial regimes to minimize risk of crop loss to disease. Development of biomarkers as indicators of stress related risks may be commercialized.Read moreRead less

Membrane attack complex/perforin-like proteins in developmental and neurobiology. This project will aim to use the fruit fly as a model system to understand how members of the perforin-like superfamily, a family of proteins more usually associated with mammalian immunity, function in embryonic and neural development. These data will eventually provide central insight into human diseases such as cancer and autism spectrum disorder.

Defining a role for non-coding RNAs in gonadal sex differentiation. This project aims to increase knowledge in the area of developmental biology, studying how gene regulation by so-called non-coding RNAs contributes to tissue patterning. The project plans to use a unique model system: gonadal development in the chicken embryo. It also plans to use novel molecular approaches that exploit the chicken model to study the role of microRNAs and a long non-coding RNA in patterning the embryonic gonad. ....Defining a role for non-coding RNAs in gonadal sex differentiation.

It also plans to use novel molecular approaches that exploit the chicken model to study the role of microRNAs and a long non-coding RNA in patterning the embryonic gonad. The project aims to provide a deeper understanding of how genes operate to control tissue patterning and organogenesis. It may thus inform the field of sex determination specifically, and, more broadly, stem cell biology and tissue engineering.Read moreRead less
