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
Mapping recombination blocks in Brassica. DNA technology provides new ways to study genomes. Understanding how the genome behaves during plant breeding will help design strategies for the breeding and selection of improved crop plants.
Characterising structural variation in the canola genome. Characterising structural variation in the canola genome. This project aims to develop and apply genomic tools to identify and characterise structural genome variation in canola, a major Australian export crop, to better understand genome evolution and accelerate canola breeding. Advances in DNA sequencing revolutionise our understanding of crop genomes, their evolution and impact on the inheritance on agronomic traits. Variation of genom ....Characterising structural variation in the canola genome. Characterising structural variation in the canola genome. This project aims to develop and apply genomic tools to identify and characterise structural genome variation in canola, a major Australian export crop, to better understand genome evolution and accelerate canola breeding. Advances in DNA sequencing revolutionise our understanding of crop genomes, their evolution and impact on the inheritance on agronomic traits. Variation of genome structure between individuals could be important in the inheritance of important agronomic traits. Recent advances in technology permit the detailed characterisation of structural variation on a previously unfeasible scale. Anticipated outcomes are enhanced global food security, supporting rural Australian economies, and accelerating the improvement of other major crops.Read moreRead less

Summary
The Life And Death Of Plant Genes. My recent work has demonstrated that in contrast to animal genes, many plant genes show presence/absence variation within a species, with associated trait variation. In this project, I will explore models of gene birth and death by comparing genomes of Brassicaceae, including the model Arabidopsis and Brassica crop species. By comparing many genomes I will learn how new genes were born. I will build models that predict the likelihood of gene loss based on a gen ....The Life And Death Of Plant Genes. My recent work has demonstrated that in contrast to animal genes, many plant genes show presence/absence variation within a species, with associated trait variation. In this project, I will explore models of gene birth and death by comparing genomes of Brassicaceae, including the model Arabidopsis and Brassica crop species. By comparing many genomes I will learn how new genes were born. I will build models that predict the likelihood of gene loss based on a gene’s physical environment, function, and expression. The project will build on our understanding of plant genetic diversity. Expected outcomes of this research include the identification of key genomic elements in gene birth and loss and support strategies to improve plant cultivars.Read moreRead less
Defining the Brassica pan-genome and establishing methods for gene conversion based crop improvement. Gene content varies between individual varieties. The project aims to apply novel genomic tools to identify and characterise the fixed and variable gene content in the important crop canola and use this to understand genome evolution as well as develop tools to accelerate canola breeding.

Gene content varies between individual varieties. The project aims to apply novel genomic tools to identify and characterise the fixed and variable gene content in the important crop canola and use this to understand genome evolution as well as develop tools to accelerate canola breeding. The project team have developed and used a high-resolution genotyping approach to demonstrate that gene conversions, short recombination events which lead to the non-reciprocal exchange of genomic regions during meiosis, are abundant in crop genomes. The project aims to develop methods and resources to characterise gene conversion in canola and establish a basis for gene conversion based crop improvement.Read moreRead less
Establishing novel breeding methods for canola improvement. It is imperative to ensure reliable food production in the coming years of climate change and increasing population. Genomics offers the greatest potential to increase food production. This project will apply genomic selection methods to accelerate canola oilseed breeding to ensure continued increases in production of this important food and national export.
Improving heat and drought tolerance in canola through genomic selection in Brassica rapa. This project aims to improve heat and drought tolerance in canola by identifying stress tolerance genes in the genetically diverse turnip family. An effective large-scale screening test for heat and drought tolerance will be developed and a number of heat- and drought-tolerant lines will be identified for genomic breeding and selection.

Summary
New Brassica crop species through evolutionary breeding. This projects aims to investigate natural mechanisms by which plants evolve into new species through hybridisation, using Brassica species (canola, cabbages and mustards) as a model. Understanding these processes will allow us to make new, widely adapted Brassica crop species for agricultural production.
Advancing our understanding of plant responses to low phosphorus availability beyond the transcriptome. Phosphorus is essential for plant growth. Plants have evolved mechanisms to cope with the poor availability of phosphorus in many soils. This project will improve Australia's knowledge of how plants alter the expression of genes and proteins to activate their mechanisms for coping with poor phosphorus availability in some soils.
Towards genome methylation based crop improvement. Deoxyribonucleic acid (DNA) methylation is a form of genetic control that regulates crop performance and the crop's response to the environment. Improving understanding of the inheritance of methylation in relation to crop performance will provide the basis for methylation based breeding for climate resilient crops.
