Phloem unloading of sucrose: cloning, functional characterisation and regulation of novel membrane transporters. Sucrose is the principal form in which plant biomass, produced in photosynthetic leaves, is transported to non-photosynthetic organs for growth and storage. Sucrose transport proteins play pivotal roles in facilitating sucrose transport around plants. Hence activities of sucrose transporters directly impact on plant growth rates and crop yields. Our aim is to isolate hitherto unkno ....Phloem unloading of sucrose: cloning, functional characterisation and regulation of novel membrane transporters. Sucrose is the principal form in which plant biomass, produced in photosynthetic leaves, is transported to non-photosynthetic organs for growth and storage. Sucrose transport proteins play pivotal roles in facilitating sucrose transport around plants. Hence activities of sucrose transporters directly impact on plant growth rates and crop yields. Our aim is to isolate hitherto unknown membrane proteins that move sucrose at high rates between cells and discover their transport properties. Expected outcomes are to better understand mechanisms and regulation of sucrose transport and hence provide novel opportunities to enhance crop yield. The project will foster a productive international collaboration.Read moreRead less
Multifunctional channels as key components of biotrophic interfaces in legumes. In legumes there are two types of membrane interfaces between different genomes that are critical for growth and yield (nitrogen fixation and seed loading), which require cell-signalling pathways to control nutrient exchange. The membranes of these interfaces contain specialised proteins that form multifunctional channels through which water, uncharged molecules and electrolytes move. These channels are likely to be ....Multifunctional channels as key components of biotrophic interfaces in legumes. In legumes there are two types of membrane interfaces between different genomes that are critical for growth and yield (nitrogen fixation and seed loading), which require cell-signalling pathways to control nutrient exchange. The membranes of these interfaces contain specialised proteins that form multifunctional channels through which water, uncharged molecules and electrolytes move. These channels are likely to be responsible for supporting the bulk of transported nutrients and in controlling their exchange. We aim to discover how these channels function in nitrogen fixation and seed loading with a view to developing new technologies that may enhance crop productivity.Read moreRead less
Novel laser isotopic techniques to assess the potential for water-use efficiency improvement of Australian crops. This project aims to develop new methods to reduce the water used by grain crops while maintaining productivity by advancing knowledge of the regulation plant carbon gain and water loss.

This project aims to develop new methods to reduce the water used by grain crops while maintaining productivity by advancing knowledge of the regulation plant carbon gain and water loss. Novel laser-lased measurement systems developed and applied in this project will provide new mechanistic understanding of plant carbon-water dynamics for individual leaves and at the whole crop scale. Water availability is the most pressing environmental issue facing the Australian grain industry, so improvements in the efficiency with which water is used will have profound economic and environmental effects.Read moreRead less

Summary
Brassinosteroids and Water Stresses. Water use has become a major factor affecting agricultural development in Australia. Therefore, it is important to develop new techniques to sustain crop production in today's climate. Developing a clearer understanding of brassinosteroids, their underlying role in water stresses and their interaction with known stress-related hormones, such as abscisic acid and ethylene, will eventually enable more effective and efficient manipulation of plant growth in wate ....Brassinosteroids and Water Stresses. Water use has become a major factor affecting agricultural development in Australia. Therefore, it is important to develop new techniques to sustain crop production in today's climate. Developing a clearer understanding of brassinosteroids, their underlying role in water stresses and their interaction with known stress-related hormones, such as abscisic acid and ethylene, will eventually enable more effective and efficient manipulation of plant growth in water stressed areas. This project has the added advantage of working with a legume, a group of plants that make a substantial contribution to the Australian economy. Our increased knowledge of legume development will help underpin future growth of this sector. Read moreRead less
Genetic and Hormonal Regulation of Plant Growth. Leguminous plants make a substantial contribution to the Australian economy. To ensure future growth, we need to know more about how legume development is regulated. Genetic mutants, typically affecting the growth-promoting gibberellin plant hormones, played a key role in the green revolution, which transformed agriculture world-wide. Recent results show that gibberellin acts in concert with another hormone, auxin. We will generate new auxin-relat ....Genetic and Hormonal Regulation of Plant Growth. Leguminous plants make a substantial contribution to the Australian economy. To ensure future growth, we need to know more about how legume development is regulated. Genetic mutants, typically affecting the growth-promoting gibberellin plant hormones, played a key role in the green revolution, which transformed agriculture world-wide. Recent results show that gibberellin acts in concert with another hormone, auxin. We will generate new auxin-related mutants that will help us to understand how auxin and auxin-mediated interactions affect crop architecture and performance. Further benefit will accrue from training of students in state-of-the-art techniques, and the generation of new germplasm for use by other researchers and plant breeders. Read moreRead less
Genetic regulation of photomorphogenesis in legume crops to meet changing agronomic needs. 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.

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
Translocated signals regulating stem cell (meristem) activity in legumes. Translocation channels of phloem and xylem allocate nutrients to growing plant organs. They also mediate communication between organs through transport of signals that elicit responses to developmental and environmental cues. The most important sites for signal transduction are the stem cells of root and shoot apical meristems. This project will discover and identify these signals using a metabolomic/proteomic approach an ....Translocated signals regulating stem cell (meristem) activity in legumes.

They also mediate communication between organs through transport of signals that elicit responses to developmental and environmental cues. The most important sites for signal transduction are the stem cells of root and shoot apical meristems. This project will discover and identify these signals using a metabolomic/proteomic approach and relying on a unique feature of lupin that permits collection of transport fluids. The project will identify ways to modify signal action to enhance performance of legumes.Read moreRead less
