Reduced Water Consumption in Commercial Malting Processes. The successful outcome for the project will be the production of barley varieties that can be successfully malted with a single steep, rather than the conventional two steeps currently employed. The objective will be achieved through the reduction of cell wall beta-glucan in barley grain. This will result in water savings of around 40%, or 1,500 megalitres per annum, for the Australian malting industry. The 1,500 megalitres saving in ....Reduced Water Consumption in Commercial Malting Processes. The successful outcome for the project will be the production of barley varieties that can be successfully malted with a single steep, rather than the conventional two steeps currently employed.

This will result in water savings of around 40%, or 1,500 megalitres per annum, for the Australian malting industry. The 1,500 megalitres saving in water use would be sufficient to support the domestic water consumption of 30,000 people, based upon the use of 140 litres per person per day that was recently achieved in Brisbane.Read moreRead less
Channels for improved crop salt and water stress tolerance. Water and salt are critical factors for the Australian agricultural industry. Crops use proteins called aquaporins to move water across cell membranes, and a newly discovered subset of these proteins can also transport salts. This project aims to reveal the molecular pathways that regulate water and salt transport via aquaporins using multidisciplinary techniques in genetics, molecular biology and electrophysiology.

Deciphering how plants control water and salt co-transport. This project aims to increase our understanding of how plant cells regulate solute transport. Crop growth depends on water uptake and transport, and the rapid movement of water across plant cell membranes requires transporters such as aquaporins. Preliminary data indicates that a series of signals can switch aquaporins between functioning as highly selective water channels and salt transport channels. The project aims to reveal the mole ....Deciphering how plants control water and salt co-transport. This project aims to increase our understanding of how plant cells regulate solute transport. Crop growth depends on water uptake and transport, and the rapid movement of water across plant cell membranes requires transporters such as aquaporins. Preliminary data indicates that a series of signals can switch aquaporins between functioning as highly selective water channels and salt transport channels. The project aims to reveal the molecular pathways that regulate water and salt co-transport, using genetics, molecular biology, and electrophysiology data to decipher how plants regulate and coordinate aquaporin solute transport during growth and in osmotic adjustment. The project has the potential to lead to improvements in crop-plant solute transport traits, enhanced agricultural productivity, and yield stability in saline and water limited environments.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

The green marine macroalga Caulerpa taxifolia is one of the world's worst invasive species. In Australia 'exotic strains' of this alga are a listed pest species. Invasions in NSW and SA have caused environmental harm and managing them has cost $10 million since 2000. We propose to integrate ecology, physiology and genetic analyses to provide data to better respond to this pest, potentially savings millions of dollars per year. We will produce the first empirical evidence of the effects of climate change and ocean acidification on this marine pest, in the context of increasing coastal human populations.Read moreRead less
Developing biotechnology solutions for improving phosphate acquisition in plants using functional genomics in rice. Global supplies of the most currently used phosphate fertilisers are predicted to be exhausted in less than a century. These fertilisers are non-renewable resources based on phosphate rock deposits and their use are key drivers of both plant production costs and environmental damage in Australia and internationally.

Global supplies of the most currently used phosphate fertilisers are predicted to be exhausted in less than a century. These fertilisers are non-renewable resources based on phosphate rock deposits and their use are key drivers of both plant production costs and environmental damage in Australia and internationally. Using the power of genetic and functional genomics analyses in rice, this project will reveal key controllers of phosphate acquisition in plants. Hence, novel biotechnology based solutions can be implemented in a variety of cereal crops to aid reduced use of phosphate fertiliser in agriculture and unlock the large phosphate pool not used by plants in soil.Read moreRead less
Understanding why aluminium and other trace metals are toxic to plants - the key to improving crop yield in degraded soils. Aluminium toxicity drastically reduces plant growth in acid soils, costing Australia approximately $1.5 billion per annum in lost productivity. This project will aim to identify the reasons behind the toxicities of aluminium and other metals and has the potential to increase yields in 50 per cent of Australia’s agricultural land which is acidic.
