The dynamics of organic matter turnover in soils to improve the productivity of Australia's agricultural industries. Two recent national reports on the soils issues facing Australian agriculture (Reeves et al, 1997; CSIRO, 2000) concluded that soil structural degradation remains, after salinisation, our major threat to the sustainability of agricultural production. This research will provide fundamental understanding of how the dynamics of organic matter turnover benefit aggregate formation and ....The dynamics of organic matter turnover in soils to improve the productivity of Australia's agricultural industries. Two recent national reports on the soils issues facing Australian agriculture (Reeves et al, 1997; CSIRO, 2000) concluded that soil structural degradation remains, after salinisation, our major threat to the sustainability of agricultural production. This research will provide fundamental understanding of how the dynamics of organic matter turnover benefit aggregate formation and stability. This will advance the understanding of organic matter from simply considering the quantity of carbon present, to one of predicting the short- and long-term benefits to soil structure. This approach is innovative in the study of soil health, and has the potential to greatly advance the development of conservation farming systems.Read moreRead less

The Insect-Plant Chemical Ecology Network (IPCEN). We bring together plant molecular biology, entomology and analytical chemistry to transform three leading fields of Australian research into an advanced science with far reaching capabilities in innovative research and applied outcomes. Expertise studying the biochemical pathways that produce specific plant compounds and expertise in insect recognition and response to these chemicals will be brought together.

We bring together plant molecular biology, entomology and analytical chemistry to transform three leading fields of Australian research into an advanced science with far reaching capabilities in innovative research and applied outcomes. Expertise studying the biochemical pathways that produce specific plant compounds and expertise in insect recognition and response to these chemicals will be brought together. This will lead to new research outcomes and solutions to problems in agriculture, horticulture, forestry and protection of Australia's native flora. Researchers are struggling to create these links, constrained by disciplinary boundaries and geographical isolation. Key industries and researchers already support this proposal.Read moreRead less
Systemic control of nodule proliferation. We aim to clone and characterize the functions of the supernodulation (NTS-1) locus of soybean using positional cloning and functional genomics approaches. Supernodulation fascinatingly results from a mutant Nts-1 gene functioning in the shoot, although the phenotype is expressed as excessive nodule proliferation in the root. The cloned gene will be used to monitor expression changes after inoculation with Bradyrhizobium, treatment with nitrate, nod-fac ....Systemic control of nodule proliferation. We aim to clone and characterize the functions of the supernodulation (NTS-1) locus of soybean using positional cloning and functional genomics approaches. Supernodulation fascinatingly results from a mutant Nts-1 gene functioning in the shoot, although the phenotype is expressed as excessive nodule proliferation in the root. The cloned gene will be used to monitor expression changes after inoculation with Bradyrhizobium, treatment with nitrate, nod-factor, xylem exudates and phytohormones. We will use RT-PCR, in situ hybridisation and reporter gene expression in transgenic plants. Microarray analysis of soybean ESTs (4200 arrayed) will analyse concurrent gene expression changes in both root and shoot.Read moreRead less

Plants and plant-based industries are essential for the provision of food, clothing and building materials and underpin the economies of rural communities. Plant yield and quality and the biodiversity of natural systems are dramatically reduced by disease. The fundamental knowledge gained from our research will enable manipulation of the factors that enhance disease resistance resulting in a significant benefit to Australian agriculture and protection of our natural resources. The current reliance for disease control on chemicals that damage the environment will be reduced and our research will contribute directly to the provision of cheaper, simpler and more effective methods of control.

Functional genomics approaches to the mechanisms of starch mobilisation in Arabidopsis. Starch is a key carbon and energy reserve that underpins plant growth. This in turn underpins much of Australia's $60 billion agriculture industry. Starch also provides most of the calories in the human diet and is a renewable commodity supporting manufacturing industries. Dependence of society on starch will increase as it becomes used more for novel materials and for bio-ethanol production, which in turn w ....Functional genomics approaches to the mechanisms of starch mobilisation in Arabidopsis. Starch is a key carbon and energy reserve that underpins plant growth. This in turn underpins much of Australia's $60 billion agriculture industry. Starch also provides most of the calories in the human diet and is a renewable commodity supporting manufacturing industries. Dependence of society on starch will increase as it becomes used more for novel materials and for bio-ethanol production, which in turn will create new jobs in the rural economy. A major quality problem in cereal grain is pre-harvest starch breakdown caused by warm wet weather triggering events associated with germination. By understanding starch metabolism in plants we will be better able to manage and enhance growth of crop plants, starch production and seed quality.Read moreRead less

Understanding the roles of small RNAs and their pathways is a new field of research that is giving, and will continue to give profound insights into how multicellular organisms regulate gene expression at a genomic level. Research in this area has already led to RNA interference technology, by which almost any gene can be switched off, and there is considerable potential for other gene silencing and trait modification technologies to emerge.

Metabolomic and genetic approaches to the discovery of genes that direct carbon partitioning in plants. Plants make starch, sucrose, cell walls (fibre), oil, organic acids, vitamins and other products of great economic and social importance.

Plants make starch, sucrose, cell walls (fibre), oil, organic acids, vitamins and other products of great economic and social importance. The partitioning of carbon resources into such products determines crop productivity and quality. This partitioning is strongly influenced by nutrients, water and salinity. The powerful genomics resources of Arabidopsis including the new discipline of metabolomics, will be deployed to understand the regulation of carbon partitioning in leaves and to discover genes that direct partitioning. National research capability will be enhanced and new resources will be generated to breed crops with improved yield potential and product quality under varied environmental conditions.Read moreRead less
