Understanding the role of endogenous siRNAs in the maintenance of genomic defenses. The inappropriate expression of retrotransposons can cause increased genomic instability. The underlying molecular pathways that control retrotransposon expression are not known. This project proposes to investigate this question at a molecular level how naturally occurring small endogenous noncoding RNAs (endo-siRNAs) enforce the epigenetic silencing of retrotransposons and examine the likely impact of endo-siRN ....Understanding the role of endogenous siRNAs in the maintenance of genomic defenses. The inappropriate expression of retrotransposons can cause increased genomic instability. The underlying molecular pathways that control retrotransposon expression are not known. This project proposes to investigate this question at a molecular level how naturally occurring small endogenous noncoding RNAs (endo-siRNAs) enforce the epigenetic silencing of retrotransposons and examine the likely impact of endo-siRNAs expression in the packaging and maintenance of retrotransposons. Understanding this fundamental question will advance the scientific knowledge of small RNA functions in our genomic defense systems. Read moreRead less
Discovering sex determining genes in a reptile with genetic and environmental sex determination. Reptile sex determination is particularly fascinating because it is triggered either by genes on sex chromosomes or by the nest temperature. This project will identify and characterise candidate sex determining genes in a model reptile to understand how genes control sexual differentiation and how they interact with temperature.
Was an ancient bird-like sex chromosome system ancestral to reptiles and mammals? Recent discoveries reveal amazing similarity in the sex chromosomes of distantly related animals. This project will use advanced DNA technology to explore diverse sex chromosomes in reptiles to discover whether this signifies ancient and unsuspected common ancestry, or the convergent redeployment of genes and chromosomes predisposed to determine sex.
Improving access to phylogenomic resources for under-resourced species: a new look at existing tools. This project will have an impact on our understanding of how to most effectively use existing genomic resources to benefit a wider range of species and to better design new genomic resources. By doing so, improved access to genomic resources will be provided to species that currently have few options.
Genomic signatures of adaptive diversification in woodland Eucalyptus. This project aims to map the sources of adaptive alleles underlying diversification is to reveal insights into the mechanisms of speciation. The source of the raw material for evolution can have significant impacts on the speed with which populations can adapt. An emerging pattern in speciation research is the importance of ancient alleles and introgressed genes, which differ in the genomic signatures left by selection. Eucal ....Genomic signatures of adaptive diversification in woodland Eucalyptus.

The source of the raw material for evolution can have significant impacts on the speed with which populations can adapt. An emerging pattern in speciation research is the importance of ancient alleles and introgressed genes, which differ in the genomic signatures left by selection. Eucalyptus offers a unique opportunity to explore these modes of evolution using the latest genomic tools. Improving our understanding of adaptation and genetic variation in woodland eucalypts is expected to make a significant contribution to their conservation, management and restoration.Read moreRead less

Distributed memory cluster:
This project aims to establish a new supercomputing facility. The NSW research community has used high performance computing (HPC) to achieve major breakthroughs across a diverse range of disciplines including astrophysics, bioinformatics, environmental science, information technology and engineering. As the use of HPC increases, the application-specific needs of the research community become more diverse, requiring greater flexibility as well as higher performance. The present facility is no longer internationally competitive, and is hampering progress in cutting edge research. The new cluster is designed to provide a greater than 10-fold increase in computing capability.Read moreRead less

The molecular basis of division of labour in the beehive. This study will dissect the genes and gene networks underpinning behaviour using cutting edge molecular and computational techniques. As a model, this project will study the division of labour in a social insect, the honeybee.
Genome-wide discovery of translation control mechanisms. This project aims to reveal currently unknown molecular details of protein synthesis, a step of gene expression that is central to all of life. To achieve this, innovative methods based on next-generation sequencing will be deployed in the yeast model organism.

Historical pest genomes inform debate about how rapid evolution proceeds. This project plans to compare the genomes of archived and contemporary specimens to discover how two key Australian pest moths have adapted to insecticides, aiding prediction of how they may respond in the future. Agricultural pest species are often capable of rapid adaptation to insecticides, resulting in widespread genetic resistance.

This project plans to compare the genomes of archived and contemporary specimens to discover how two key Australian pest moths have adapted to insecticides, aiding prediction of how they may respond in the future. Agricultural pest species are often capable of rapid adaptation to insecticides, resulting in widespread genetic resistance. Does this resistance build on existing genetic variation, or are fresh mutations used to produce a fast adaptive response? How do adaptive strategies differ among key Australian pests? This project aims to answer these questions and advance understanding of mechanisms that underpin rapid evolution to improve approaches toward pest management and agricultural protection.Read moreRead less

Beyond genes: How the extended genotype of plants facilitates adaptation. Adaptation to environmental change is required for species to persist, however rapid environmental change may exceed the limits of traditional genetic adaptation leading to widespread decline. Recent work has highlighted the 'extended genotype' as an additional factor influencing adaptive phenotypes.

Adaptation to environmental change is required for species to persist, however rapid environmental change may exceed the limits of traditional genetic adaptation leading to widespread decline. Recent work has highlighted the 'extended genotype' as an additional factor influencing adaptive phenotypes. This project aims to examine DNA methylation and polyploidisation as both a cause and consequence of the adaptation process using natural populations of the model cereal Brachypodium distachyon. The project aims to determine the architecture of these features and how their variability impacts adaptive traits such as flowering time. From the functional role of the extended genotype the project endeavours to predict and select genetic responses to the environment.Read moreRead less
