Is transport of miRNAs essential for plant development? This project will provide knowledge of how a new class of biologically active molecule (micro RNA) regulates expression of genes at sites in the plant that are critical for growth and development. MicroRNAs are believed to influence the size and shape of plants, how rapidly they grow and how well they produce and fill seeds.

This project will provide knowledge of how a new class of biologically active molecule (micro RNA) regulates expression of genes at sites in the plant that are critical for growth and development. MicroRNAs are believed to influence the size and shape of plants, how rapidly they grow and how well they produce and fill seeds. These molecules are part of a group of bioactive signals that move throughout the plant, functioning like hormones but directly influencing how well critical genes work. Their exploitation holds great promise for manipulating plant performance and enhancing crop yields. Read moreRead less
Carboxylate exudation and phosphate nutrition in Hakea prostrata (Proteaecea). Nonmycorrhizal Proteaceae are very successful in acquiring phosphate from nutrient-impoverished soils; their cluster roots account for this. They are also extremely sensitive to phosphate toxicity. We will elucidate aspects of production and release of carboxylates that are associated with functioning of cluster roots, using Hakea prostrata (Proteaceae) as a model. Types and rates of exudation by cluster roots, as in ....Carboxylate exudation and phosphate nutrition in Hakea prostrata (Proteaecea). Nonmycorrhizal Proteaceae are very successful in acquiring phosphate from nutrient-impoverished soils; their cluster roots account for this. They are also extremely sensitive to phosphate toxicity. We will elucidate aspects of production and release of carboxylates that are associated with functioning of cluster roots, using Hakea prostrata (Proteaceae) as a model. Types and rates of exudation by cluster roots, as influenced by development and environmental signals, will be assessed. Our findings will provide key information on adaptive mechanisms associated with both phosphate acquisition from phosphate-fixing soils and phosphate toxicity.Read moreRead less
Genome Approaches to Investigate Metabolic Coordination in Plant Cells. Metabolism of C and N in legume nodules requires interaction between the symbiotic bacteria and plant organelles, particularly metabolism in plastids and mitochondria. Fixed N is assimilated through the de novo synthesis of purines in both plastids and mitochondria. However, each of the nine pathway enzymes is encoded by a single gene, indicating each protein is targeted to both organelles. Purine metabolism will provide ....Genome Approaches to Investigate Metabolic Coordination in Plant Cells. Metabolism of C and N in legume nodules requires interaction between the symbiotic bacteria and plant organelles, particularly metabolism in plastids and mitochondria. Fixed N is assimilated through the de novo synthesis of purines in both plastids and mitochondria. However, each of the nine pathway enzymes is encoded by a single gene, indicating each protein is targeted to both organelles. Purine metabolism will provide a model to assess the more general occurrence of dual-targeted proteins in plants. The aim is to identify and eventually exploit the signalling mechanism(s) that mediate communication between plastids and mitochondria.Read moreRead less

Summary
Oxidative stress bioanalytical facility. The primary national benefit of this application is that it will provide a currently unavailable, state-of-the-art facility for Australian scientists to define precisely how changes in cellular redox state contribute to biological processes relevant to health and diseases. The facility will uniquely complement, and in many cases integrate with existing facilities in this area of research in Australia. It will act as a platform for major national and inter ....Oxidative stress bioanalytical facility. The primary national benefit of this application is that it will provide a currently unavailable, state-of-the-art facility for Australian scientists to define precisely how changes in cellular redox state contribute to biological processes relevant to health and diseases. The facility will uniquely complement, and in many cases integrate with existing facilities in this area of research in Australia. It will act as a platform for major national and international research collaborations, develop cutting-edge technology and unique local skills, and contribute to Australia maintaining a leading position in redox-related research in biology and medicine. In doing so, the facility will increase the likelihood of gaining future, value-adding funding.Read moreRead less
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

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
