The sponge genome project and the evolution of multicellularity: using comparative genomics and developmental biology to reconstruct the first animals. Recently the entire genome from a living fossil - a sponge from the Great Barrier Reef - was sequenced (jointly supported by the ARC and US Department of Energy). As this genome is assembled and analysed, many of the fundamental biological processes that underlie the construction and evolution of all animals, including humans, will be revealed. ....The sponge genome project and the evolution of multicellularity: using comparative genomics and developmental biology to reconstruct the first animals. Recently the entire genome from a living fossil - a sponge from the Great Barrier Reef - was sequenced (jointly supported by the ARC and US Department of Energy). As this genome is assembled and analysed, many of the fundamental biological processes that underlie the construction and evolution of all animals, including humans, will be revealed. In addition, sponge genomics will fuel innovations in medicine and biotechnology. Specifically, sponges are renowned for their capacity to synthesise bioactive compounds used in drug development, and high-grade silica used for semi-conductor construction. This project will identify the gene networks controlling these biosynthetic processes.Read moreRead less
Molecular and genetic analysis of epigenetic components in a model plant. Australia is a major exporter of agricultural food crops thus producers must maintain their competitive advantage in order to compete on the world stage. Food crops unfortunately have large, complex genomes that are not sequenced and a generation time of months that makes research outcomes slow to achieve. This project proposes to utilise a model plant that has a small completely sequenced genome and a short generation tim ....Molecular and genetic analysis of epigenetic components in a model plant. Australia is a major exporter of agricultural food crops thus producers must maintain their competitive advantage in order to compete on the world stage. Food crops unfortunately have large, complex genomes that are not sequenced and a generation time of months that makes research outcomes slow to achieve. This project proposes to utilise a model plant that has a small completely sequenced genome and a short generation time making it ideal to study the fundamental biological process of RNA silencing. Discoveries and outcomes from this project may have the potential to benefit Australian crops, ecosystems and human health.Read moreRead less

Discovery of novel microRNA components will provide new strategies for confronting a diverse array of challenges Australia faces, such as the increasing rates of certain cancers in our population, to stresses on our crop plants faced with environmental changes. The biological mechanisms underlying these disparate problems are unified by microRNA involvement in many instances. By finding microRNA controlling factors common to all higher organisms, we expect our community will benefit from the increased knowledge base that will help our researchers adopt new strategies in fighting diseases and improving our agricultural industry.Read moreRead less
Endosymbiotic DNA transfer. Interorganellar DNA movement is a major force in evolution. In higher organisms, the prokaryotic ancestors of mitochondria and chloroplasts donated many genes to the nucleus. Plants have unique potential in studies of the mechanisms that have driven genome evolution. We established experimentally that DNA moves from the chloroplast to the nucleus at high frequency and this provided us with a world lead in this scientifically new area. The relocated genes contribute to ....Endosymbiotic DNA transfer. Interorganellar DNA movement is a major force in evolution. In higher organisms, the prokaryotic ancestors of mitochondria and chloroplasts donated many genes to the nucleus. Plants have unique potential in studies of the mechanisms that have driven genome evolution. We established experimentally that DNA moves from the chloroplast to the nucleus at high frequency and this provided us with a world lead in this scientifically new area. The relocated genes contribute to the number and diversity of genes and gene function. Genetically manipulated (GM) crops use the chloroplast compartment to make high levels of protein, necessitating a full understanding of how transgenes behave within the cellular and the external environment.Read moreRead less
Improved models to understand the genomic architecture of complex traits. This project aims to improve modelling of the genetics underlying complex traits. The project will develop and test models for using genome-wide genetic data to investigate how much heritability (genetic effect) underlies traits of interest, where it lies in the genome, and how much of it is shared across traits. The new models will be implemented in statistical algorithms in a freely-available software package. This proj ....Improved models to understand the genomic architecture of complex traits.

The new models will be implemented in statistical algorithms in a freely-available software package. This project expects to increase understanding of biological mechanisms, the efficiency of genetic association analyses and the accuracy of genomic prediction, including the effects of interventions. The project will adapt human models to a wider range of organisms, in particular bacteria.Read moreRead less

Modern molecular tools have lead to an explosion in genome projects and unification of all areas of biology. The most basic need for such research is access to improving technologies for detecting DNA fingerprints that distinguish genetically-diverse genes, and determining which genes are "switched on" or 'off' in various situations. Real time PCR technology, pioneered by The University of Queensland (UQ) and Southern Cross University (SCU) using ARC funding in 1996, is now the technology of choice for much of this research. This project will provide high-throughput equipment for real time PCR, and will develop complementary high-throughput "nanoparticle" DNA genotyping technologies, with applications to medicine and agriculture.

Trafficking of DNA between chloroplast and nucleus in higher plants. Reliably high levels of diverse proteins can be produced in plant chloroplasts. Environmental risks are considered low for chloroplast genes because they are not transmitted by pollen. However, we recently discovered that DNA escapes from the tobacco chloroplast to the nucleus with unexpectedly high frequency. The associated environmental risks require immediate investigation. This project will determine the fate of chloroplast ....Trafficking of DNA between chloroplast and nucleus in higher plants. Reliably high levels of diverse proteins can be produced in plant chloroplasts. Environmental risks are considered low for chloroplast genes because they are not transmitted by pollen. However, we recently discovered that DNA escapes from the tobacco chloroplast to the nucleus with unexpectedly high frequency. The associated environmental risks require immediate investigation. This project will determine the fate of chloroplast DNA that has moved to the nuclear genome and gain insight into the evolutionary and environmental consequences of chloroplast DNA escape. The ubiquity of DNA escape also will be studied in an edible crop with a small genome, tomato.Read moreRead less
