The facility will also provide a platform to rapidly accelerate our present capacity for Xenopus oocyte expression analysis of nutrient transport proteins. This facility will greatly aid our current research quantum in this field and allow for new discoveries related to nutrient transport in plants.Read moreRead less
Symbiotic transport proteins in legumes. Some plants form a symbiosis with soil bacteria (rhizobia) that convert atmospheric nitrogen to ammonia which is then supplied to the plant. This enables legumes to grow without application of nitrogen-based fertilizer, avoiding environmental problems such as run-off and land degradation, thereby contributing to sustainable agriculture practise. We will investigate the interactions between plant and rhizobia, focusing on identifying genes and proteins wh ....Symbiotic transport proteins in legumes.

This enables legumes to grow without application of nitrogen-based fertilizer, avoiding environmental problems such as run-off and land degradation, thereby contributing to sustainable agriculture practise. We will investigate the interactions between plant and rhizobia, focusing on identifying genes and proteins which govern nutrient exchange between the partners and development of the special structures in the roots that house the bacteria. Subsequent manipulation of these genes and proteins may allow us to identify control points and enhance nitrogen fixation.

Domestication of blue-banded bees for greenhouse pollination. The tomato industry is currently shifting towards production in greenhouses, which allows climate control and improved pest management. A lack of pollinators is an obstacle to this move. This project will establish protocols for large-scale use of native blue-banded bees as pollinators in greenhouses, especially for tomatoes. Pollination by native bees increases fruit weight by 15%, comparable to the effects of bumblebees used overs ....Domestication of blue-banded bees for greenhouse pollination. The tomato industry is currently shifting towards production in greenhouses, which allows climate control and improved pest management. A lack of pollinators is an obstacle to this move. This project will establish protocols for large-scale use of native blue-banded bees as pollinators in greenhouses, especially for tomatoes. Pollination by native bees increases fruit weight by 15%, comparable to the effects of bumblebees used overseas. Significant economic, environmental and health benefits are expected from this project. The outcome will satisfy an industry need and remove an environmental threat by finding indigenous substitutes for alien bumblebees.Read moreRead less
Integrating a physical and functional genetic map of Prunus dulcis. Genome wide physical mapping is the centrepiece of current genomics research in virtually all plant and animal species. The proposal seeks to champion the development of Prunus dulcis (Rosaceae) as a model perennial species towards parity with other plant model systems for gene discovery and validation. The Rosaceae represents a rich repository of genes of relevance to perenniality, adaptation, sustainable agriculture, health a ....Integrating a physical and functional genetic map of Prunus dulcis. Genome wide physical mapping is the centrepiece of current genomics research in virtually all plant and animal species. The proposal seeks to champion the development of Prunus dulcis (Rosaceae) as a model perennial species towards parity with other plant model systems for gene discovery and validation. The Rosaceae represents a rich repository of genes of relevance to perenniality, adaptation, sustainable agriculture, health and nutrition and the bioindustries. Ultimately, comparative genomics across the family will advance molecular eco-genetics via dissection of traits determining adaptive response. Access to user-friendly molecular markers will also bring greater precision to breeding programmes. Read moreRead less

Upgrade and expansion of Newcastle Plant Growth Facility. The project will upgrade and expand the Newcastle Plant Growth Facility. The upgrades will improve glasshouse environments for the production of high quality plant material. This outcome will be achieved through increasing solar transmittance and more effective temperature control. Expansion will address unmet demand for standard and PC2 plant growth space.

The project will upgrade and expand the Newcastle Plant Growth Facility. The upgrades will improve glasshouse environments for the production of high quality plant material. This outcome will be achieved through increasing solar transmittance and more effective temperature control. Expansion will address unmet demand for standard and PC2 plant growth space. Together the infrastructure additions will enhance productivity and excellence of core areas of plant biology research at Newcastle in nutrient transport, cell development as well as environment management and rehabilitation . In addition, they will underpin new collaborative initiatives at the interfaces between plant biology with transgenic delivery of reproductive vaccines and phytoremediation.Read moreRead less
Protecting cereal grain development at high temperatures. This project aims to investigate new temperature-responsive factors that regulate cereal grain development to protect grain production under heat stress. The new research will leverage international collaborations with access to cutting-edge genetic and technological resources, and refine novel X-ray imaging techniques in Australia, to observe how temperature affects flower structure and function in barley and rice.

This project aims to investigate new temperature-responsive factors that regulate cereal grain development to protect grain production under heat stress. The new research will leverage international collaborations with access to cutting-edge genetic and technological resources, and refine novel X-ray imaging techniques in Australia, to observe how temperature affects flower structure and function in barley and rice. Favourable mutations that optimise plant yield and fitness will be defined and explored in other, more complex, cereals such as wheat. Expected outcomes will be fundamental breakthroughs in understanding how plants respond to, and buffer, the effects of heat to lead to translational breeding strategies that bolster grain yield.Read moreRead less
Targeting chloroplasts to enhance crop salt tolerance. Yield losses in crop plants due to increasingly saline soils are linked to the effects of salt on chloroplasts. By comparing chloroplast water- and salt-transport mechanisms of closely related salt-loving and salt-sensitive plants, this Fellowships aims to discover how chloroplasts maintain function in saline conditions. Novel biophysics and molecular techniques will be used to characterise transporters in model plants, and proof-of-concept ....Targeting chloroplasts to enhance crop salt tolerance. Yield losses in crop plants due to increasingly saline soils are linked to the effects of salt on chloroplasts. By comparing chloroplast water- and salt-transport mechanisms of closely related salt-loving and salt-sensitive plants, this Fellowships aims to discover how chloroplasts maintain function in saline conditions. Novel biophysics and molecular techniques will be used to characterise transporters in model plants, and proof-of-concept complementation experiments aim to confer salt tolerance on sensitive plants. These fundamental insights are likely to lead to rapid, step-change improvements in salt tolerance, especially in agriculturally relevant crops, to benefit Australia’s agri-industry and ensure food security in the future.Read moreRead less

This project aims to investigate the role of a regulatory locus in the regulation of ammonium transport in plants and the interacting genetic and biochemical signalling promoting the interaction. Ammonium is an important nutrient source for plant growth and development. It has been recently identified that a new transport mechanism (AMF1 ) mediates ammonium transport across legume root nodule cellular membranes. AMF1 was identified through a transcriptional interaction with a membrane localised bHLHm1 transcription factor. Both bHLHm1 and AMF1 belong to a unique chromosomal regulatory locus common across sequenced dicot plant species.Read moreRead less
Transport systems that underpin nitrogen efficient maize. This project aims to define the nitrogen transport network involved in the uptake, storage and redistribution of inorganic nitrogen (nitrate and ammonium) over the developmental life cycle of maize. This information will provide novel insight into the genetic control of nitrogen use in maize and other cereal crops.
