ARC Centre for Kangaroo Genome. In this Australian-led Kangaroo Genome Project, we will map and characterize the tammar wallaby genome at the molecular level. 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 ....ARC Centre for Kangaroo Genome. In this Australian-led Kangaroo Genome Project, we will map and characterize the tammar wallaby genome at the molecular level. 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
Developmental regulation of plant mitochondrial genome structure and copy number. Recombination is a major driving force behind mitochondrial DNA evolution and is responsible for the occurrence of cytoplasmic male sterile plants that are used by plant breeders to obtain high yield hybrids. A better understanding of the mechanisms that underlie mitochondrial and chloroplast genome maintenance and segregation will be a major fundamental scientific advance that will permit an integrated picture of ....Developmental regulation of plant mitochondrial genome structure and copy number. Recombination is a major driving force behind mitochondrial DNA evolution and is responsible for the occurrence of cytoplasmic male sterile plants that are used by plant breeders to obtain high yield hybrids. A better understanding of the mechanisms that underlie mitochondrial and chloroplast genome maintenance and segregation will be a major fundamental scientific advance that will permit an integrated picture of the interactions between the three plant genomes (nuclear, mitochondrial and chloroplastic). It is also a pre-requisite for the future manipulation of the cytoplasmic genomes leading to new ways to develop varieties with modified cytoplasms.Read moreRead less
LATERAL GENE TRANSFER, GENOME EVOLUTION AND THE EMERGENCE OF NEW DISEASES CAUSED BY FUNGAL PATHOGENS IN THE PLEOSPORALES. Normal evolution involves the transfer of genes within species. The modest variation between progeny powers natural selection. Lateral gene transfer is the movement of genetic material between species. It allows for large evolutionary steps. Although common in bacteria, it has rarely been described convincingly in higher organisms such as fungi, plants or animals. We have evi ....LATERAL GENE TRANSFER, GENOME EVOLUTION AND THE EMERGENCE OF NEW DISEASES CAUSED BY FUNGAL PATHOGENS IN THE PLEOSPORALES. Normal evolution involves the transfer of genes within species. The modest variation between progeny powers natural selection. Lateral gene transfer is the movement of genetic material between species. It allows for large evolutionary steps. Although common in bacteria, it has rarely been described convincingly in higher organisms such as fungi, plants or animals. We have evidence that one group of fungal pathogens is particularly adept at acquiring new genes that enable them to cause new diseases. We will determine the mechanism and frequency of gene transfer in this group. The work had fundamental significance in evolutionary biology, in the emergence of new diseases and in the use of genetically-modified organisms.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
