Wheat biomarkers - the effect of nitrogen withdrawal on the proteome and peptidome. Nitrogen is a crucial macroelement for plants. Its importance is highlighted by the wide use of agricultural nitrogen fertilizers in Australia and world wide. This comes at substantial costs for the environment and the economy, due to low nitrogen use efficiency of cereals and environmental impacts. By understanding plant responses to nitrogen we can improve nitrogen efficiency.

Its importance is highlighted by the wide use of agricultural nitrogen fertilizers in Australia and world wide. This comes at substantial costs for the environment and the economy, due to low nitrogen use efficiency of cereals and environmental impacts. By understanding plant responses to nitrogen we can improve nitrogen efficiency. This project will identify proteins and peptides as biomarkers of plant responses to nitrogen withdrawal. Such biomarkers can be used in plant breeding and in agricultural prediction of plant nitrogen requirements with the potential to reduce agricultural costs and environmental impacts.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

Continual improvement to agricultural plant production is key to maintaining future sustainable growth in Australian agriculture. Our respective research teams are focussed on improving how plants utilise both nitrogen and water. Many questions remain with respect to where, how and when plants use and or access these important nutrients. The proposed facility will enable plant scientists to begin in-depth analysis of both nitrogen transport mechanisms and the ability to model root development and water allocation in crop species. This research will ultimately lead to improved knowledge on how plants respond to their environment and where modifications can be made to generate sustainable crops suited to Australian agriculture.Read moreRead less

Agro-ecosystem sensor capability for elevated carbon dioxide-free air research facility: This project will provide infrastructure upgrades to the Australian Grains Free Air Carbon dioxide Enrichment (AGFACE) facility, globally the only FACE facility in low rainfall, non-irrigated agri-ecosystems. Low rainfall, non-irrigated agriculture systems play a very significant role in global crop production and are predicted to be negatively affected by climate changes. The requested infrastructure will enable direct, plot scale measurements of crop water balance and water status, including crucial influence factors such as root growth and architecture and crop canopy temperatures, and allow manipulation experiments to develop adaptation options to improve crop resource use efficiencies.

This research hub aims to provide Australian growers and industrial stakeholders with improved plant materials to maximise production, environmental sustainability and profitability. In particular, the research aims to improve the nitrogen delivery capacity of legumes and their resilience to abiotic stress, which will be an important consideration as our climate changes. Grain legumes are often grown in rotation with cereal crops for their high nutritional seed value and their unique ability to develop a self-sufficient nitrogen-fixing symbiosis with soil bacteria. Maintaining legume productivity against the challenges of climate change and the need for increased food production is important to the future of Australian agriculture.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.

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

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, cytosolic pH and aluminium uptake across the plasma membrane 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
