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

System-level characterisation of the siphonophore, Indo-Pacific man o' war. The Indo-Pacific man o' war (bluebottle), is a cnidarian from the siphonophore order. These animals frequent Australian beaches in swarms and cause thousands of stings every year. The project proposes to profile the genome, transcriptome, epigenome, and proteome of the bluebottle to gain insight into its life cycle, its behaviour, and toxins. Expected outcomes include the generation of novel information related to bluebo ....System-level characterisation of the siphonophore, Indo-Pacific man o' war. The Indo-Pacific man o' war (bluebottle), is a cnidarian from the siphonophore order. These animals frequent Australian beaches in swarms and cause thousands of stings every year. The project proposes to profile the genome, transcriptome, epigenome, and proteome of the bluebottle to gain insight into its life cycle, its behaviour, and toxins. Expected outcomes include the generation of novel information related to bluebottle gene regulation and its toxin repertoire, which will be highly beneficial for the design of future sting treatment strategies. Given that the bluebottle is a colony made of functionally specialised polyps, this study will also provide significant novel insight into the origins and evolution of animal multicellularity.Read moreRead less
Understanding disease resistance gene evolution across the Brassicaceae. Pan genomes represent the diversity of a species, including structural and sequence variation, which cannot be provided by a reference genome alone.

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
Identifying the diversity and evolution of loci associated with adaptation to aridity/heat and salinity in ancient cereal crops. This project will use ancient grains of wheat, barley and rye to find 'lost' genetic diversity at key genes associated with resistance to aridity, salt and disease. This project will make the proteins of key genes, and study their interaction with the environment over time by measuring ions in the grains to reveal the ancient environmental conditions.

Summary
Role of DNA methylation in response to low nutrient availability in plants. DNA methylation (mC) is a covalent modification of DNA essential for the establishment and maintenance of correct gene expression patterns and recently suggested to be responsive to some environmental cues in plants. Using cutting edge technologies, this project aims to identify nutrient stress-induced mC changes and investigate the role that these changes may play in transcriptional regulation, as well as assessing whet ....Role of DNA methylation in response to low nutrient availability in plants. DNA methylation (mC) is a covalent modification of DNA essential for the establishment and maintenance of correct gene expression patterns and recently suggested to be responsive to some environmental cues in plants. Using cutting edge technologies, this project aims to identify nutrient stress-induced mC changes and investigate the role that these changes may play in transcriptional regulation, as well as assessing whether these changes can be transmitted to the next generation to confer intergenerational stress responsiveness. Altogether this project aims to provide fundamental knowledge of the role of mC in plant gene regulation and stress response as well as paving the way for the next generation of novel crop-improvement strategies.Read moreRead less
