Finding the missing links in salt and water transport in plants. Grain crops and horticultural plants use proteins called aquaporins to move water across cell membranes, but a group of these proteins can also transport some important nutrient ions as well as toxic sodium ions. This project aims to reveal the molecular pathways that regulate water and ion transport via aquaporins using advanced techniques in biophysics and molecular biology. These results will provide novel insights into how plan ....Finding the missing links in salt and water transport in plants. Grain crops and horticultural plants use proteins called aquaporins to move water across cell membranes, but a group of these proteins can also transport some important nutrient ions as well as toxic sodium ions. This project aims to reveal the molecular pathways that regulate water and ion transport via aquaporins using advanced techniques in biophysics and molecular biology. These results will provide novel insights into how plants coordinate and adapt to changing water and salt conditions, addressing a missing link in how ions and water move in and out of plant vacuoles. Benefits include an expanded, innovative range of targets for plant breeding programs to improve plant productivity in our changing climate.Read moreRead less
ARC Centre of Excellence in Plant Energy Biology. We propose a novel approach to improve sustainable yield by optimising the overall efficiency of energy capture, conversion and use by plants. Efficiency gains in metabolism, transport, and development will be more effective than optimising single nutrient inputs or product outputs. Improving multiple parameters simultaneously is a necessary solution to the increasing demand for more crop yield from finite land, water, and nutrient resources. Unp ....ARC Centre of Excellence in Plant Energy Biology. We propose a novel approach to improve sustainable yield by optimising the overall efficiency of energy capture, conversion and use by plants. Efficiency gains in metabolism, transport, and development will be more effective than optimising single nutrient inputs or product outputs. Improving multiple parameters simultaneously is a necessary solution to the increasing demand for more crop yield from finite land, water, and nutrient resources. Unpredictable environmental challenges adversely affect plant growth and further perturb plant energy balance, limiting yield. The epigenetic controls, gene variants and signals discovered will provide a new basis for sustainable productivity of crops and will future-proof plants in changing climates.Read moreRead less
Control points in nitrogen uptake: enhancing the response of cereals to nitrogen supply and demand. Vast amounts of nitrogen fertiliser are applied to cereal crops to maintain yields. By uncovering what limits nitrogen uptake in cereals, this project will provide the scientific basis for improving nitrogen use efficiency and decreasing fertiliser use, with significant economic and environmental benefits.
Controlling accumulation of elements in the shoots of higher plants by manipulating processes in specific cell types in the roots. This project will provide novel, fundamental understanding of the processes controlling accumulation of elements in the shoots of plants.

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.

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

Summary
Getting to the root of salt-tolerance in the model cereal crop, barley. The root system is the first part of the plant to sense high concentrations of sodium and chloride ions in saline soils. The ability of roots to maintain growth in response to salinity is an important adaptation, increasing root soil exploration for nutrient and water uptake. The aim of this project is to identify the molecular mechanisms that control and regulate root growth in response to salinity using barley as a cereal ....Getting to the root of salt-tolerance in the model cereal crop, barley. The root system is the first part of the plant to sense high concentrations of sodium and chloride ions in saline soils. The ability of roots to maintain growth in response to salinity is an important adaptation, increasing root soil exploration for nutrient and water uptake. The aim of this project is to identify the molecular mechanisms that control and regulate root growth in response to salinity using barley as a cereal model. The knowledge gained in barley will provide important information for increasing salinity tolerance in other Australian cereal crops, most notably wheat.Read moreRead less
Dissecting chloride transport in plants to secure an untapped source for improving plant productivity. Chloride and nitrate are central to physiological processes that determine crop yield and food production, but their uptake and transport within the plant body are antagonistic.

Chloride and nitrate are central to physiological processes that determine crop yield and food production, but their uptake and transport within the plant body are antagonistic. This project will gain a fundamental understanding of the mechanisms underlying this antagonism. This will provide new tools for improving salinity tolerance and the efficiency of fertiliser use, which can be used for the development of new crop varieties. Improving these traits will be essential if we are to successfully address the threats to Australian and global food security posed by salinity, and the rising economic and environmental costs of inefficient fertiliser use.Read moreRead less

A signalling pathway for future crop improvement. This project aims to decipher a mechanism that controls plant gas exchange – the process that emits oxygen, loses water, absorbs carbon dioxide and is essential for plant growth for food, fibre and fuel production. When plants encounter stressful conditions such as drought, high temperatures or flooding, they adapt their physiology to maintain viability and re-establish growth. This project will manipulate stress-induced gamma-aminobutyric acid’s ....A signalling pathway for future crop improvement.

When plants encounter stressful conditions such as drought, high temperatures or flooding, they adapt their physiology to maintain viability and re-establish growth. This project will manipulate stress-induced gamma-aminobutyric acid’s capacity to control plant gas exchange to help secure future food production, through improving crop tolerance to stresses such as low water availability and high temperatures – conditions associated with a changing Australian climate.Read moreRead less
