Molecular pathways controlling light-regulated development in legumes. Legumes are widely grown as forage and grain crops and make a substantial contribution to the Australian economy. Light is an important determinant of plant architecture and productivity and we need to know more about how development is regulated by light in this important plant group. The natural light environment faced by plants is complex and varies with crop density, season and time of day. Understanding the interaction o ....Molecular pathways controlling light-regulated development in legumes. Legumes are widely grown as forage and grain crops and make a substantial contribution to the Australian economy. Light is an important determinant of plant architecture and productivity and we need to know more about how development is regulated by light in this important plant group. The natural light environment faced by plants is complex and varies with crop density, season and time of day. Understanding the interaction of photoreceptors and plant hormones in the control of growth is vital for manipulating crops to meet changing agronomic requirements. Training of students in state-of-the art techniques and the generation of new germplasm for use by other researchers and plant breeders will be other significant outcomes of the project.Read moreRead less
Ion transporters regulating plant adaptive responses to salinity and the modes of their control by compatible solutes in plant cells. Plants respond to saline conditions by a significant elevation in the level of compatible solutes in the cytosol. It appears that these solutes are not directly involved in conventional osmoprotection, but instead have a regulatory role in cell metabolism. This project will apply a range of state-of-the-art biophysical and molecular techniques to investigate the m ....Ion transporters regulating plant adaptive responses to salinity and the modes of their control by compatible solutes in plant cells. Plants respond to saline conditions by a significant elevation in the level of compatible solutes in the cytosol. It appears that these solutes are not directly involved in conventional osmoprotection, but instead have a regulatory role in cell metabolism. This project will apply a range of state-of-the-art biophysical and molecular techniques to investigate the modes of control exercised by compatible solutes over the activity of major plasma membrane transporters involved in plant adaptive responses to salinity. The work will substantially advance our understanding of salt tolerance and will provide a sound basis for genetic engineering of salt tolerant crops.Read moreRead less

The project examines the behavioural and welfare implications of alternative models of intra household decisions. A framework that integrates the household's earnings and expenditure decisions will be proposed and applied. The project introduces new measures of spousal power in making decisions and examines its impact on household outcomes. A satisfactory econometric methodology to test the conventional unitary model will be developed and applied. The usefulness of this research is underlined by examining the policy implications in areas that range from taxation in the developed country context to child health, child labour and gender bias in case of developing countries.Read moreRead less
Protecting Australia’s food future: shared responsibility for biosecurity. This project aims to investigate whether Australia’s ‘shared responsibility’ approach to biosecurity is capable of facing the growing threat from exotic pests and diseases. Through the analysis of policy documents and the use of semi-structured interviews, this project intends to contribute to a deeper understanding of the inter- and intra-organisational characteristics that influence implementation of biosecurity. Expect ....Protecting Australia’s food future: shared responsibility for biosecurity. This project aims to investigate whether Australia’s ‘shared responsibility’ approach to biosecurity is capable of facing the growing threat from exotic pests and diseases. Through the analysis of policy documents and the use of semi-structured interviews, this project intends to contribute to a deeper understanding of the inter- and intra-organisational characteristics that influence implementation of biosecurity. Expected outcomes include crucial insights into the capacity of a shared responsibility approach to protect agri-food production against biological threats, and the forms of institutional change that may be needed to enhance responsiveness to those threats. This in turn will benefit Australia's biosecurity system.Read moreRead less
Disease in endangered species: The importance of multiple-host infection and spatial structure. Pathogens are increasingly recognised as threats to endangered species. Managing such threats requires models to assess alternative strategies. Most current models deal with a single host and single pathogen, without spatial structure, although multiple-host pathogens pose the greatest conservation threats. This project develops a new generation of spatially-structured multiple-host models, and applie ....Disease in endangered species: The importance of multiple-host infection and spatial structure. Pathogens are increasingly recognised as threats to endangered species. Managing such threats requires models to assess alternative strategies. Most current models deal with a single host and single pathogen, without spatial structure, although multiple-host pathogens pose the greatest conservation threats. This project develops a new generation of spatially-structured multiple-host models, and applies them to two case studies. The first is the chytrid fungus that is thought to have lead to widespread declines and extinctions of frogs in Australia and overseas. The second is birdpox and malaria that have led to the extinction and endangerment of much of Hawaii's endemic avifauna.Read moreRead less
Genetic control of flowering in legumes. Flowering in plants is strongly regulated by environmental factors, with important consequences for their natural distribution and use in agriculture. This project will isolate genes, characterize genetic diversity and dissect molecular mechanisms that regulate flowering, contributing to fundamental biology, crop improvement and research training.
Neural correlates of performance trade-offs and interference in dual-task performance. Our daily lives are characterised by our ability to produce and sustain a wide range of different movement patterns and to deliberately change patterns as the situation demands. In this project we seek to understand the relationship between brain processes, attentional demands, and the control and learning of coordinated behaviour. A further aim will be to examine how this relationship may be altered as a re ....Neural correlates of performance trade-offs and interference in dual-task performance. Our daily lives are characterised by our ability to produce and sustain a wide range of different movement patterns and to deliberately change patterns as the situation demands. In this project we seek to understand the relationship between brain processes, attentional demands, and the control and learning of coordinated behaviour. A further aim will be to examine how this relationship may be altered as a result of aging, degenerative disease, or brain damage. This research will provide a foundation upon which rehabilitation strategies can be developed for the movement impaired.Read moreRead less
Investigating the genetic basis for heterogeneous susceptibility of Tasmanian devils to a novel infectious cancer. This project will use genetics and modelling to reveal why Tasmanian devils in northwest Tasmania are not dying from facial tumour disease, a new, unusual infectious cancer threatening this iconic carnivore with extinction. This project will predict extinction risk, develop management options, and provide a new template for managing emerging wildlife diseases.
Facilitatory and inhibitory mechanisms during interlimb coordination in young and older adults. The project seeks to understand how people coordinate their limbs and the factors which limit and enhance this capacity. This is of critical importance because coordination is a dominant deficit in aging and in patients suffering brain insult and neurodegenerative diseases. Disruption of this capacity compromises individual work productivity, mobility and independence. Proficient motor functioning is ....Facilitatory and inhibitory mechanisms during interlimb coordination in young and older adults. The project seeks to understand how people coordinate their limbs and the factors which limit and enhance this capacity. This is of critical importance because coordination is a dominant deficit in aging and in patients suffering brain insult and neurodegenerative diseases. Disruption of this capacity compromises individual work productivity, mobility and independence. Proficient motor functioning is an important lifestyle factor as humans age and deficits in coordinated muscle activity will increase the risk of falls which are the leading cause of injury in elderly adults. Identification of changes in brain processes involved in interlimb coordination will allow for the development of strategies to improve motor functions in the aged.Read moreRead less
