Novel compounds as natural herbicides for weed management. The development by weeds of herbicide resistance has undermined these systems and limited prospect for development of new chemicals with different modes of actions through traditional methods. Such methods of searching for new herbicides are yielding diminishing returns and the associated costs are becoming prohibitive.

The development by weeds of herbicide resistance has undermined these systems and limited prospect for development of new chemicals with different modes of actions through traditional methods. Such methods of searching for new herbicides are yielding diminishing returns and the associated costs are becoming prohibitive.
This project aims to develop herbicides by evaluating, isolating and identifying novel natural compounds present in a range of weeds and crop plants.
The outcomes will be reduced herbicide inputs, and the development of a new group of natural herbicides to counteract the threat imposed by the development of herbicide resistance.

Functional and structural characterisation of Defective embryo and meristems (Dem) proteins involved in plant development. The proposed research will lead to advances in understanding the regulation of plant development, a process impacting on agriculture, environmental management and human health, areas designated as national research priorities.

The proposed research will lead to advances in understanding the regulation of plant development, a process impacting on agriculture, environmental management and human health, areas designated as national research priorities. This understanding is required for modifying plant growth and architecture to fit particular environments, for example generating plants with more extensive and deeper roots to mine the soil moisture and nutrients to enhance crop productivity in Australia, and maintaining the competitive advantage of Australian agriculture in view of the range of environmental conditions encountered in this country. The project will also contribute to the health of the Australian population through consumable plants in the diet.Read moreRead less

Summary
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
Plant cell wall - aluminium interactions: a role in aluminium stress. Soil acidity, resulting in Al toxicity, affects production on circa 50% of Australia's intensively used agricultural land, resulting in 8.5 times more foregone agricultural income than dryland salinity (National Land and Water Resources Audit, 2001). Often, remediation with lime is not possible or affordable. By understanding Al reactions with cell wall components, we aim to identify root parameters related to Al resistance by ....Plant cell wall - aluminium interactions: a role in aluminium stress. Soil acidity, resulting in Al toxicity, affects production on circa 50% of Australia's intensively used agricultural land, resulting in 8.5 times more foregone agricultural income than dryland salinity (National Land and Water Resources Audit, 2001). Often, remediation with lime is not possible or affordable. By understanding Al reactions with cell wall components, we aim to identify root parameters related to Al resistance by plants. These parameters will be useful as selection markers to identify and breed Al-tolerant crop genotypes. This, in turn, will improve yields and farm profitability, allowing farmers to use lime to prevent further acidification. This increases sustainability of cropping operations on the 50 Mha with acid soils.Read moreRead less

Aquaporins in roots: resolving observations linking them to diverse processes in water relations and plant productivity. The knowledge we gain will benefit Australia by allowing better management of plant water use and productivity. This is critical for adaptation to a drier climate where water is a critical resource.

The knowledge we gain will benefit Australia by allowing better management of plant water use and productivity. This is critical for adaptation to a drier climate where water is a critical resource. Large quantities of water move through aquaporin proteins in plants, therefore our understanding of these and the way they influence other processes in plant growth could enable us to manipulate plants to conserve water or to extract it more efficiently from the soil. Molecular aspects of the project could reveal new unexploited links between water and plant productivity. High calibre PhD and Honours students will also be educated to maintain the momentum of international excellence within Australia in the field of plant water relations.Read moreRead less
Active bicarbonate transporters from cyanobacteria: physiological properties, genetic regulation, and introduction into plants for crop improvement.

An intriguing set of membrane transport proteins that accumulate bicarbonate into marine cyanobacterial cells will be investigated. These proteins support the crucial process of photosynthetic carbon dioxide fixation in marine cyanobacteria (blue-green algae), which are major contributors to global carbon dioxide sequestration and form one of the foundations of the marine food web. These bicarbonate "transporters" will also be transferred into a model plant system to test whether the efficiency of photosynthesis can be improved, with corresponding gains in the water-use efficiency of these plants. If successful this technology will have profound global implications for improving crop production in semi-arid areas.Read moreRead less
