Deciphering the regulatory principles of metazoan development. This proposal aims to elucidate how regulatory elements in the genome, known as enhancers, determine the identity and function of animal tissues. Currently, it is believed that enhancers cannot be traced across evolutionarily distant animals. The project uses novel concepts, computational and molecular approaches to identify deeply conserved enhancers. It further dissects the mechanism of function by proteomics and high-throughput ge ....Deciphering the regulatory principles of metazoan development. This proposal aims to elucidate how regulatory elements in the genome, known as enhancers, determine the identity and function of animal tissues. Currently, it is believed that enhancers cannot be traced across evolutionarily distant animals. The project uses novel concepts, computational and molecular approaches to identify deeply conserved enhancers. It further dissects the mechanism of function by proteomics and high-throughput genomics. The expected outcomes will overturn our current view on enhancer evolution and reposition our understanding of how enhancers are functionally encoded in the genome. The work is an important contribution to understanding cellular complexity and species evolution with wide-ranging impact in genetics.Read moreRead less
Unravelling the biochemical fingerprint of Australian native plants for sustainable farm forestry and other applications. Dryland salinity is an issue of national significance due to its impact on primary industries which contribute billions of dollars to our economy. However, millions of hectares of arable land are now affected by salinity, with devastating effects on crops, native plants, water quality and wildlife.

Dryland salinity is an issue of national significance due to its impact on primary industries which contribute billions of dollars to our economy. However, millions of hectares of arable land are now affected by salinity, with devastating effects on crops, native plants, water quality and wildlife. This project works with the rural community and exploits the unique gene pool of certain Australian salinity-tolerant plants for environmental benefits (revegetation, salinity control) and simultaneous economic returns through using these for timber and perennial fodder. The project thus addresses the national priorities of preventing the expansion of salinity, putting it to sustainable uses and preserving biodiversity.Read moreRead less

Summary
Evolution of genome architecture. The project aims to understand how changes to genome architecture over evolutionary time are linked to the diversity of animal morphology. Our genome sequence is arranged into higher order structures that enable coordinated gene expression. The appropriate expression of genes in time and space is necessary to produce the multitude of cell types that make up a multicellular organism. Yet, to date, genome topology is poorly explored, especially between species. Th ....Evolution of genome architecture. The project aims to understand how changes to genome architecture over evolutionary time are linked to the diversity of animal morphology. Our genome sequence is arranged into higher order structures that enable coordinated gene expression. The appropriate expression of genes in time and space is necessary to produce the multitude of cell types that make up a multicellular organism. Yet, to date, genome topology is poorly explored, especially between species. The project involves comparisons of the 3D structure of genomes in divergent species. These findings are expected to inform the underlying principles of gene regulation in animals and species evolution.Read moreRead less
Establishment of the Australian Cane Toad Genome Program. The Cane Toad is one of Australia's greatest environmental menaces, and is in the top 100 of the "World's Worst invader species". Over a billion toads infest Northern Australia, and they will soon invade WA and move further into NSW. Their poisons and voracious appetite could make many native mammals, birds and reptiles extinct. The only possibility to eradicate the Toad is by biological control, but there is no known control agent. We wi ....Establishment of the Australian Cane Toad Genome Program. The Cane Toad is one of Australia's greatest environmental menaces, and is in the top 100 of the "World's Worst invader species". Over a billion toads infest Northern Australia, and they will soon invade WA and move further into NSW. Their poisons and voracious appetite could make many native mammals, birds and reptiles extinct. The only possibility to eradicate the Toad is by biological control, but there is no known control agent. We will identify the 'Toad's Achilles' heel' against which control agents can be developed. We can do this by identifying every Toad gene. This project forms the first step to this goal by establishing the Australian Cane Toad Genome Program. Toad control will help preserve Australia's unique natural heritage.Read moreRead less

The aim of this multicentred study (University of Sydney, Australian National University, Australian Institute of Sport) is to find genes in the cardiac and musculoskeletal systems that are involved in modifying human physical performance. From this knowledge, it is proposed to develop novel physical training programs in our national sporting institutions based on an individual's genetic information. In the broader community, knowledge of genes which contribute to the normal and healthy functioning of the cardiac and musculoskeletal systems will be invaluable in understanding and preventing breakdowns in these body systems.Read moreRead less
Old genes learning new tricks: characterising regulatory changes driving increased heart complexity during vertebrate evolution. The heart has dramatically increased in morphological complexity during vertebrate evolution but the molecular basis driving these major changes remains unknown. Using comparative genomics approaches, this project will explore changes in the regulation of genes involved in heart formation that lead to changes in cardiac structure.

The heart has dramatically increased in morphological complexity during vertebrate evolution but the molecular basis driving these major changes remains unknown. Using comparative genomics approaches, this project will explore changes in the regulation of genes involved in heart formation that lead to changes in cardiac structure. It will elucidate for the first time the cardiac regulatory repertoire in zebrafish and will compare it with that of fly and mouse using cutting-edge bioinformatics pipelines. This work will unravel cardiac-specific regulatory modifications that give rise to evolutionary changes. On a broader scale, it will shed new light on the role of regulatory innovations over gene innovations in the emergence of new traits.Read moreRead less
Developing the Dunnart as a Model Species for Marsupial Research. The project aims to develop a marsupial model capable of genome manipulations to take our understanding of marsupial biology to the next level. In doing so, the project would produce the first comprehensive transcriptome data defining early cell lineage specification in a marsupial.

The project aims to develop a marsupial model capable of genome manipulations to take our understanding of marsupial biology to the next level. In doing so, the project would produce the first comprehensive transcriptome data defining early cell lineage specification in a marsupial. Combined with similar data from mouse and human, it would enable us to examine diversity in early mammals. In addition, it would identify cohorts of genes with fundamental roles in differentiation of the earliest cell lineages: trophoblast, pluriblast and hypoblast. The project may identify maternally localised transcripts with a marsupial-specific role in trophoblast–pluriblast specification, giving new insights into the fundamental pathways maintaining pluripotency in mammals and the evolution of the mammalian genome.Read moreRead less

Marsupial genomes are uniquely valuable because they provide comparisons that reveal new human genes, regulatory sequences and marsupial-specific genes. These will deliver new products and information useful for medicine, industry, agriculture and conservation. We will construct integrated genetic and physical maps of the genome, clone the whole genome as large inserts in BAC vectors, and build a "golden path" with minimal overlap. We will construct libraries of expressed genes from tammar tissues and array them for use in analysing gene expression.Read moreRead less
