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

A new regional analytical biological TEM (BioTEM) will provide critical support to acclaimed medical and biological groups researching nationally significant age-related health, agricultural and environmental questions. The BioTEM, for example, will allow a unique opportunity to detect metal uptake and accumulation in bone-forming cells. This research will provide insight into metal induced afflictions, such as nasal ulcer, lung cancer, contact dermatitis and hypersensitivity reactions like asthma. The BioTEM will also be used to study how plants take up nutrients and how they use these compounds for growth, development and reproduction. Successes in this research will transfer to the important development of salt-tolerant plant species.Read moreRead less
The regulation of skeletal muscle mass. This project aims to delineate a pathway involved in regulating skeletal muscle mass, and examine whether disrupting mitochondrial phospholipid synthesis affects mitochondrial structure and function, causing muscle wasting.

Proteomic techniques to assess oxidative stress in muscle wasting diseases. Australia will experience a significant increase in the proportion of its population that is over 65 years of age over the next 50 years. There will be an increased demand for health services related to injury from falls unless effective preventive strategies are put in place. Loss of muscle mass contributes to falls, so development of preventative strategies has the potential for considerable benefits.

Australia will experience a significant increase in the proportion of its population that is over 65 years of age over the next 50 years. There will be an increased demand for health services related to injury from falls unless effective preventive strategies are put in place. Loss of muscle mass contributes to falls, so development of preventative strategies has the potential for considerable benefits. Oxidative stress is a key intermediary in muscle wasting. This PhD project examines a possible mechanism by which oxidative stress causes muscle wasting. An appropriately tailored therapy to minimise oxidative stress has the potential to ameliorate loss of muscle mass.
