Unique epigenetic states in plant stem cell niches for safeguarding genome integrity. Plant stem cells are the foundation cells of all plant growth and development, including generation of the reproductive cells. Therefore, it is critical that stem cells defend against attacks that may damage the genome. A unique epigenetic state in plant stem cell niches has been discovered that may protect the genome from damage due to parasitic DNA elements. Using sophisticated genomics, genetics, and cellula ....Unique epigenetic states in plant stem cell niches for safeguarding genome integrity. Plant stem cells are the foundation cells of all plant growth and development, including generation of the reproductive cells. Therefore, it is critical that stem cells defend against attacks that may damage the genome. A unique epigenetic state in plant stem cell niches has been discovered that may protect the genome from damage due to parasitic DNA elements. Using sophisticated genomics, genetics, and cellular technologies, this project will investigate how stem cell epigenetic state is linked to genome defence, how environmental stresses can disrupt the defence system, and the role of the system in driving new genetic diversity. This knowledge is of high importance as agricultural crops enter an era of increasingly challenging conditions.Read moreRead less
Perceptual suppression mechanisms in the Drosophila brain. This project will investigate common processes underlying three means to losing conscious perception: selective attention, sleep and general anaesthesia. By studying these suppression mechanisms in a genetic model, the fly Drosophila melanogaster, fundamental processes will be highlighted that are required in the brain for maintaining perception in general.
Deciphering the regulation and function of the epigenome in eukaryotic development and stress response. The epigenome is an additional regulatory code superimposed upon plant and animal genomes that controls how they operate. This project will aim to understand the information encoded in the epigenome and how it changes in development and environmental stress, enabling manipulation of its function in crops and correction of its dysfunction in disease.

Summary
Encounters with hominins: the history of human arrival in Sahul. This project aims to provide a detailed understanding on the remarkably complex encounters between archaic and modern human populations in Island Southeast Asia, New Guinea and Australia during the Pleistocene. The project plans to provide the largest collection of human genetic diversity from this vast geographical region and significantly advance current knowledge on one of the most intriguing questions in human evolution.

This project aims to provide a detailed understanding on the remarkably complex encounters between archaic and modern human populations in Island Southeast Asia, New Guinea and Australia during the Pleistocene. The project plans to provide the largest collection of human genetic diversity from this vast geographical region and significantly advance current knowledge on one of the most intriguing questions in human evolution. These insights are expected to bring important social and cultural benefits for Australia by unveiling the singularly deep genetic history of Aboriginal Australians, including their ancient connection to indigenous communities from Indonesia and New Guinea that extends back to when people first arrived in Australia.

Evolutionary analyses of short-read sequences from pooled samples. This project aims to provide biologists with a means of making sound, statistical inferences about evolution by using next-generation data from mixed samples. When biologists make statements about history, they use evolutionary trees, frequently reconstructed from the genetic data of many individuals. Next-generation sequencing provides large amounts of genetic data at low cost, but biologists have difficulty using these data for ....Evolutionary analyses of short-read sequences from pooled samples. This project aims to provide biologists with a means of making sound, statistical inferences about evolution by using next-generation data from mixed samples. When biologists make statements about history, they use evolutionary trees, frequently reconstructed from the genetic data of many individuals. Next-generation sequencing provides large amounts of genetic data at low cost, but biologists have difficulty using these data for evolutionary research, particularly when they sample mixtures of DNA from many individuals. The anticipated value of this project is that it allows evolutionary biologists to capitalise on the benefits of next-generation sequencing, without sacrificing their ability to make reliable inferences about history.Read moreRead less

In this project we combine unique expertise, international collaboration and novel genetic information about Australia's unique egg-laying mammals (echidna and platypus) to investigate major aspects of reproduction. This work will address fundamental aspects of sex chromosome biology and advance our understanding of mammalian reproduction. The knowledge gained will have application in captive breeding and conservation of these extraordinary Australian mammals. The project also provides opportunity to train research students in cutting edge molecular biology and informatics.Read moreRead less

Western Australian Zebrafish Facility. Zebrafish facility: The zebrafish as a model vertebrate organism is fast approaching the importance of the laboratory mouse. This facility will enable the research community to fully embrace the zebrafish as a powerful research tool.
Complex trait analyses based on genome-wide approaches. This project aims to develop whole genome approaches that can improve the estimation and prediction power by using information from the dynamic genetic architecture of complex traits (i.e. the changes of genetic characteristics and effects when varying effective population size and genetic backgrounds).

This project aims to develop whole genome approaches that can improve the estimation and prediction power by using information from the dynamic genetic architecture of complex traits (i.e. the changes of genetic characteristics and effects when varying effective population size and genetic backgrounds). The project intends to deliver advanced statistical models, efficient algorithms and design by combining data from close relatives, population samples or from different populations (e.g. multi-ethnicities or multi-breeds). The expected outcome is to better understand the dynamic architecture of complex traits and develop methods with improved power, precision and accuracy in genomic analyses.Read moreRead less
The roles and regulators of new plant cells linked to root transport. Plant genomics has moved to the single cell resolution, allowing precise investigations of previously hidden cell types and cell states that respond to environmental stress and that vary among differentially adapted plant populations. Here, we will extend our pioneering efforts that have mapped and discovered novel root cell types, to determine their salt and nutrient stress responses, and to elegantly dissect the underling ca ....The roles and regulators of new plant cells linked to root transport. Plant genomics has moved to the single cell resolution, allowing precise investigations of previously hidden cell types and cell states that respond to environmental stress and that vary among differentially adapted plant populations. Here, we will extend our pioneering efforts that have mapped and discovered novel root cell types, to determine their salt and nutrient stress responses, and to elegantly dissect the underling causal genetic variation. The unique cell markers and regulatory networks will be validated with tissue specific and transgenic tools that can work across a host of plant species to reveal adaptive cellular responses to harsh environmental conditions.Read moreRead less
Epigenetics, environment, and evolution. This project will aim to understand how biological information can exist and be passed from one generation to the next without being encoded in the gene sequence, and also how our early environment can modify this so-called "epigenetic" information to alter disease risk.
