Pan genomes represent the diversity of a species, including structural and sequence variation, which cannot be provided by a reference genome alone. In this project we will characterise resistance gene diversity across the Brassicaceae pan genomes. Through comparison with resistance gene diversity in cultivated Brassica species we will understand selection underlying resistance gene evolution in wild species and subsequent domestication and breeding. Knowledge on how variation affects disease susceptibility, especially to the devastating fungal pathogen blackleg, and contributes to phenotypic variation, will lead to improved plant protection strategies and increased crop resilience.Read moreRead less
The More the Merrier? Investigating copy number variation in Brassicas. This project intends to develop an understanding of how gene copy number variation affects disease susceptibility to help in the design of novel plant protection strategies. Gene copy number variants (CNVs) are segments of DNA that have been duplicated or lost in the genome of one individual or line with respect to another. CNVs have been shown to contribute significantly to phenotypic differences in humans, including diseas ....The More the Merrier? Investigating copy number variation in Brassicas. This project intends to develop an understanding of how gene copy number variation affects disease susceptibility to help in the design of novel plant protection strategies. Gene copy number variants (CNVs) are segments of DNA that have been duplicated or lost in the genome of one individual or line with respect to another. CNVs have been shown to contribute significantly to phenotypic differences in humans, including disease susceptibility, and the same seems to apply in plants. This project aims to apply the genome sequences for Brassica species to detect CNVs from re-sequencing data. Knowing how this variation affects an individual or line’s disease susceptibility, especially to the devastating fungal pathogen blackleg, could improve plant protection strategies and crop production.Read moreRead less
Population Genetics of Fungal Pathogens that Threaten the Biosecurity of Australia's Eucalypts. Many new pathogens and diseases are emerging on exotic eucalypt plantations throughout the world. These emerging diseases pose a threat to native eucalypt forests and plantations in Australia. Vigilant quarantine measures are necessary to prevent the introduction of potentially devastating pathogens into Australia. However, incursions do occur and there is a great need to study these pathogens now, ....Population Genetics of Fungal Pathogens that Threaten the Biosecurity of Australia's Eucalypts. Many new pathogens and diseases are emerging on exotic eucalypt plantations throughout the world. These emerging diseases pose a threat to native eucalypt forests and plantations in Australia. Vigilant quarantine measures are necessary to prevent the introduction of potentially devastating pathogens into Australia. However, incursions do occur and there is a great need to study these pathogens now, before they enter Australia. By studying the population genetics of pathogens, their evolutionary potential can be estimated and with that the extent of the risk they pose to native and planted eucalypts in Australia can be determined.Read moreRead less
Simultaneous analysis of root-derived plant defences and the associated microbiome. Australia is dependent on sustainable agricultural yields, which need to be maintained or improved. This production capacity is currently under threat by new and existing diseases which are predicted to worsen with climate change. This project will provide a global picture of how disease resistance and soil microbial communities are causally linked, and provide new strategies for disease control. In doing so, it ....Simultaneous analysis of root-derived plant defences and the associated microbiome. Australia is dependent on sustainable agricultural yields, which need to be maintained or improved. This production capacity is currently under threat by new and existing diseases which are predicted to worsen with climate change. This project will provide a global picture of how disease resistance and soil microbial communities are causally linked, and provide new strategies for disease control. In doing so, it will develop intellectual property (IP) and infrastructure that can be used in soil health management. This will provide many benefits to Australia, including sustainable agriculture in the context of climate variability and an increased demand for food, biomaterials and biofuels.Read moreRead less
From the pouch to the grave: age and sex related changes in immunity in the Tasmanian devil. Tasmanian devils face extinction in the wild due to the emergence of a contagious cancer: Devil Facial Tumour Disease (DFTD). A comprehensive understanding of the devil immune system is necessary to better understand the disease and develop a vaccine against it. This project will characterise immune responses of healthy devils throughout life, from the pouch, to onset of puberty, to old age. This project ....From the pouch to the grave: age and sex related changes in immunity in the Tasmanian devil. Tasmanian devils face extinction in the wild due to the emergence of a contagious cancer: Devil Facial Tumour Disease (DFTD). A comprehensive understanding of the devil immune system is necessary to better understand the disease and develop a vaccine against it. This project will characterise immune responses of healthy devils throughout life, from the pouch, to onset of puberty, to old age. This project will then compare these responses in DFTD-affected devils to determine why DFTD affects older animals first and does not affect sexually-immature devils. Additional outcomes will include the development of novel antibiotics against human and animal diseases and an atlas of devil development using the latest imaging technologies.Read moreRead less
Whole-genome multivariate reaction norm model for complex traits. This project aims to develop a multivariate whole-genome genotype-covariate correlation and interaction model that can be applied to a wide range of existing genome-wide association study (GWAS) datasets. Genotype-covariate correlation and interaction (GCCI) are fundamental in biology but there is no standard approach to disentangle interaction from correlation in the whole-genome analyses. This project will address the key featur ....Whole-genome multivariate reaction norm model for complex traits. This project aims to develop a multivariate whole-genome genotype-covariate correlation and interaction model that can be applied to a wide range of existing genome-wide association study (GWAS) datasets. Genotype-covariate correlation and interaction (GCCI) are fundamental in biology but there is no standard approach to disentangle interaction from correlation in the whole-genome analyses. This project will address the key feature in biology, which relates to dissecting the complex mechanism of association and interaction. The proposed statistical model implemented in a context of a novel design based on multiple GWAS data sets is a paradigm shifting-tool with applications to multiple industries.Read moreRead less

Genetic regulation of developmental competence: molecular mechanisms that establish a competent state. Development is a key biological process for multicellular life. This project will study development using a simple, established experimental organism, a fungus, as a model for development in other organisms, including humans. Moreover, fungi directly impact on life at many levels and understanding their biology has direct benefits for society.
Intron splicing regulates gene silencing in Arabidopsis. Defective gene regulation (i.e. how genes switch on and off) can cause severe genetic disease in both plants and animals, including humans. This project will use plants as a model to investigate a cause of defective gene expression, and should reveal possible avenues for therapeutic intervention to correct genetic defects in plants and animals.
