What is the function of gamma-aminobutyric acid-gated anion channels in plants? The project will identify the molecular basis of gamma-aminobutyric acid (GABA) signalling in plants. This is significant because GABA regulates proteins that release molecules involved in root-soil interactions, growth, and fertilisation. The project's discoveries will allow improvement of these agronomic traits that ultimately determine crop yield.
Functional network analysis of plant metabolism in response to salinity and temperature through targeted proteomics. This project will measure changes in plant metabolism and provide methods and a pipeline for quantification and modelling. It will assess nitrogen linked metabolism under environmental stress experienced in Australian wheat cropping systems and build fundamental knowledge of changes in networks of nitrogen metabolism in model plants.
Molecular mechanisms governing the role of calcium in aluminium toxicity and tolerance in plants. Aluminium is the most important yield-limiting factor in acid soils throughout the world. The problem of aluminium toxicity is aggravated by continuous acidification of arable land. Mechanisms of aluminium toxicity in plant cells are poorly understood. The present project seeks to elucidate the molecular basis of the interaction between intracellular calcium homeostasis and plasma membrane potential ....Molecular mechanisms governing the role of calcium in aluminium toxicity and tolerance in plants.

Mechanisms of aluminium toxicity in plant cells are poorly understood. The present project seeks to elucidate the molecular basis of the interaction between intracellular calcium homeostasis and plasma membrane potential in aluminium toxicity to plants. Knowledge of primary triggers of aluminium toxicity will pay off in a breeding programme aimed at selecting crop genotypes with increased resistance to aluminium toxicity.Read moreRead less

Summary
New facilities for multiplex gas-exchange (MGX) measurements of plant performance during climate-controlled growth. Precise study of oxygen and carbon dioxide gas exchange can quantify the underlying factors responsible for plant growth. This dedicated facility will increase the scope and accuracy of Australian research into plant productivity thereby allowing improved understanding of factors affecting plants' adaptability to environmental change and plant competition or pathogen effects.

Western Australia is home to a range of world-leading plant science research groups. Establishing a world-class multi-purpose phytosphere facility in WA will enable these groups to remain at the forefront of their research fields and continue to attract high-profile international scientists and students. Such a facility will result in significant advancement of our understanding of the impact of climate change on plants through biotic stresses (e.g., disease epidemiology, plant-pathogen interactions) and in interaction with abiotic variables (e.g., CO2 concentrations, temperature, light intensity, humidity, moisture stress, airborne pollutants such as SO2), and allow crop yield optimisation in future environments.Read moreRead less

Aluminium uptake across the root-cell plasma membrane. Aluminium toxicity limits crop growth in acid soils that occupy about 24 million hectares of agricultural land in Australia. Liming can increase pH of the surface soil, but is frequently too expensive in the low-input Australian agriculture. Surface-applied lime is poorly effective in ameliorating subsoil acidity, and incorporating lime deep into the profile is prohibitively expensive and technically difficult. Hence, Al-resistant crop culti ....Aluminium uptake across the root-cell plasma membrane. Aluminium toxicity limits crop growth in acid soils that occupy about 24 million hectares of agricultural land in Australia. Liming can increase pH of the surface soil, but is frequently too expensive in the low-input Australian agriculture. Surface-applied lime is poorly effective in ameliorating subsoil acidity, and incorporating lime deep into the profile is prohibitively expensive and technically difficult. Hence, Al-resistant crop cultivars are important part of sustainable farming in Australia. This project will characterise early triggers of Al toxicity in plants, providing a foundation for increasing Al resistance in crop cultivars. Understanding the physiological basis of Al toxicity will lead to improved crop breeding strategies.Read moreRead less
Unravelling the secrets of the rhizosphere of crops. Phosphate is one of the most important limiting nutrients for crop growth and production. Plant acquisition of soil phosphate largely depends on root proliferation to accelerate soil exploration, and on phosphate bioavailability mediated by root exudates and rhizosphere microorganisms. Central to this is the need for a better understanding of the complex biogeochemical interfaces in the rhizosphere. This project explores recently developed non ....Unravelling the secrets of the rhizosphere of crops. Phosphate is one of the most important limiting nutrients for crop growth and production. Plant acquisition of soil phosphate largely depends on root proliferation to accelerate soil exploration, and on phosphate bioavailability mediated by root exudates and rhizosphere microorganisms. Central to this is the need for a better understanding of the complex biogeochemical interfaces in the rhizosphere. This project explores recently developed non-destructive imaging, isotope, and metabolism techniques to generate a systematic research tool in tracking rhizosphere interactions and imaging phosphate dynamics from macroscale to nanoscale levels. This study will provide new opportunities to improve crop nutrient use efficiency and crop production.Read moreRead less

The project’s goal is to improve crop breeding for increased efficiency of acquiring soil resources. Increasing a crop’s efficiency in capturing soil resources (water and nutrients) is an imperative task in ensuring food security. This project plans to use barley as the model cereal crop and characterise root traits in a panel of cultivars assembled to represent maximum diversity as well as in biparental mapping population followed by association and linkage mapping to identify genetic markers linked with specific root traits. These markers will be incorporated into a computer model of 3-D root structure and function. The enhanced computer model would be able to simulate optimal root systems for specific environments and generate a list of selectable root-trait markers.Read moreRead less
