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.

Structure and metabolism of bioactive carbohydrates from brown algae. Brown algae produce a diversity of species-specific carbohydrates in their cell walls that exhibit a variety of biological activities that can be exploited for the development of functional food and biopharmaceutical formulations. However, the metabolic pathways responsible for the biosynthesis of these carbohydrates are poorly characterised. This multidisciplinary project aims to understand the molecular events that control t ....Structure and metabolism of bioactive carbohydrates from brown algae. Brown algae produce a diversity of species-specific carbohydrates in their cell walls that exhibit a variety of biological activities that can be exploited for the development of functional food and biopharmaceutical formulations. However, the metabolic pathways responsible for the biosynthesis of these carbohydrates are poorly characterised. This multidisciplinary project aims to understand the molecular events that control the structure and metabolism of bioactive carbohydrates in the prominent Australian brown alga Ecklonia radiata, with particular focus on alginates and fucoidans. This knowledge will be used to produce in yeast bioactive oligosaccharides that are of high commercial interest to the biopharmaceutical industry.Read moreRead less
