An epigenetic basis for foetal programming. The social and economic impact of adult-onset diseases such as diabetes, hypertension and atherosclerosis is increasing. Evidence indicates that a mother's nutrition influences the risk of her children developing some diseases later in life. This proposal aims to elucidate the mechanism underlying this phenomenon. By understanding the mechanism through which maternal nutrition affects disease risk, we may make it possible to design early diagnosis and ....An epigenetic basis for foetal programming. The social and economic impact of adult-onset diseases such as diabetes, hypertension and atherosclerosis is increasing. Evidence indicates that a mother's nutrition influences the risk of her children developing some diseases later in life. This proposal aims to elucidate the mechanism underlying this phenomenon. By understanding the mechanism through which maternal nutrition affects disease risk, we may make it possible to design early diagnosis and intervention strategies. Our work may suggest intervention strategies - such as supplementation of at-risk mothers with key molecules such as methyl donors - during foetal and early postnatal life, which could be key to preventing premature morbidity and mortality.Read moreRead less
Regulation of principal components of the antioxidant system in table grapes. An expanded ?health-claims? system will likely be enacted by Food Standards Australia New Zealand within two years. Horticultural industries are attracted to the promotional ?point of difference? this offers.

An expanded ?health-claims? system will likely be enacted by Food Standards Australia New Zealand within two years. Horticultural industries are attracted to the promotional ?point of difference? this offers. Many health-promoting compounds are antioxidants, including polyphenols that are abundant in fruit such as grape and citrus. Antioxidants are also involved in the plant's defences against abiotic and biotic stress. Here, the WA Table Grape industry has committed funds for an APAI to study regulation of antioxidants in relation to nutritional and postharvest qualities. Effects of preconditioning with mild oxidative stresses will be assayed, postharvest, using molecular and biochemical techniques.Read moreRead less
Programming of appetite and bodyweight by the interaction of maternal diet and angiotensin during peri-natal life. The project describes a phenotype for appetite and body weight that can be altered by maternal dietary omega-3 PUFA (environmental factors), at a critical period during peri-natal life (developmental phase) and that the effect on body weight is opposite when endogenous angiotensin is increased (hormonal factor). The project aims to discover how these different factors interact to p ....Programming of appetite and bodyweight by the interaction of maternal diet and angiotensin during peri-natal life. The project describes a phenotype for appetite and body weight that can be altered by maternal dietary omega-3 PUFA (environmental factors), at a critical period during peri-natal life (developmental phase) and that the effect on body weight is opposite when endogenous angiotensin is increased (hormonal factor). The project aims to discover how these different factors interact to produce the phenotype by defining the critical period and systematically identifying genes that are expressed during this period. The effect of manipulating maternal dietary omega-3 PUFA and the role of angiotensin will then be examined. The project will discover how genetic, hormonal and environmental factors interact during the perinatal period of life to program food intake and body weight in adult life. Read moreRead less

This research proposal will be a key element in the emerging program in evolutionary and ecological functional genomics at the University of Queensland. Our studies utilize modern genomics approaches to address diverse national priorities from conservation of biological resources in the face of climate change, to understanding how genetic history contributes to drug susceptibility. The research will contribute to the intellectual foundation upon which rigorous environmental and biomedical research is built. Social impact will be seen in the training of a new generation of integrative genome biologists, and the shaping of attitudes toward the role of genetics in human biology.Read moreRead less
Genetic Basis of Variable Expression of Glycan Xeno-Autoantigens by Cattle. Meat and dairy products from cattle contain sugar structures (glycans) that are not made by humans. These structures can be recognised by the immune system and lead to allergic reactions, inflammation and potentially cancer. These non-human structures are called xeno-autoantigens or XAs. We have discovered individual cattle that do not produce one of these XAs. We will study the gene required to make XA in the XA-free ca ....Genetic Basis of Variable Expression of Glycan Xeno-Autoantigens by Cattle. Meat and dairy products from cattle contain sugar structures (glycans) that are not made by humans. These structures can be recognised by the immune system and lead to allergic reactions, inflammation and potentially cancer. These non-human structures are called xeno-autoantigens or XAs. We have discovered individual cattle that do not produce one of these XAs. We will study the gene required to make XA in the XA-free cattle to find the underlying mutation. The same approach will be used to look for natural XA-free individuals in other food species. This knowledge may enable us to create a test to facilitate the natural breeding of non-GMO, XA-free livestock to benefit Australian primary producers and provide safer food for consumers.Read moreRead less
Evaluation of Bacillus amyloliquefaciens H57 as a probiotic in livestock using animal nutrition studies and metagenomics. To improve animal production, gene sequencing will unravel how microbial communities in the rumen of sheep and cattle and the gastro intestinal tract of poultry respond to feed quality and probiotic bacteria. The animal nutrition trials will also measure weight gain and feed utilisation efficiency, particularly for nitrogen, protein and energy.

Summary
A walk on the wild side: understanding disease resistance across plants. Plants are in constant battle with pests and pathogens. Wild species host genetic diversity, providing sources of disease resistance, while the narrow genetic base of crop varieties leads to an increasing reliance on the unsustainable application of chemical fungicides. Here I will apply the latest genomics approaches to characterise disease resistance gene diversity across the plant kingdom. Comparison of gene diversity wi ....A walk on the wild side: understanding disease resistance across plants. Plants are in constant battle with pests and pathogens. Wild species host genetic diversity, providing sources of disease resistance, while the narrow genetic base of crop varieties leads to an increasing reliance on the unsustainable application of chemical fungicides. Here I will apply the latest genomics approaches to characterise disease resistance gene diversity across the plant kingdom. Comparison of gene diversity within and between plant families will improve our understanding of resistance gene evolution in wild species and the impact of domestication and breeding on resistance gene diversity. Translation of this knowledge will support breeding for crop resilience, leading to durable resistance and more sustainable crop productionRead moreRead less
