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
The role of the ammonium transport bHLHm1/AMF1 regulatory loci in plants. 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 i ....The role of the ammonium transport bHLHm1/AMF1 regulatory loci in plants. 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

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
How do plant roots align nitrogen uptake to soil opportunities? Improved nitrogen use efficiency (NUE) in crop plants is required to achieve sustainable plant agriculture practices that maximise productivity while minimising nitrogen fertiliser-dependent pollution. Current high-input monoculture plant production systems suffer from poor NUE and can contribute to local and global nitrogen pollution outcomes. Improving how plants manage their nitrogen uptake will improve NUE and help support Aust ....How do plant roots align nitrogen uptake to soil opportunities? Improved nitrogen use efficiency (NUE) in crop plants is required to achieve sustainable plant agriculture practices that maximise productivity while minimising nitrogen fertiliser-dependent pollution. Current high-input monoculture plant production systems suffer from poor NUE and can contribute to local and global nitrogen pollution outcomes. Improving how plants manage their nitrogen uptake will improve NUE and help support Australian plant agriculture. This project will investigate novel technologies that re-engineer nitrate transport activity. The project will also investigate the biochemical and molecular links between nitrogen uptake on root development required for improved plant growth.Read moreRead less
Novel methods for the production of micronutrient-enriched rice. The increasingly productive Australian rice industry generated AUD$1 billion revenue in 2012. By targeting a rice gene that we recently identified as a key regulator of iron uptake and transport, this project will produce high value, micronutrient-enriched rice grain to improve the nutritional health of people in Australia and throughout the world.
Modelling spatial and temporal dynamics of rhizosphere exudation. Existing crop root systems are poorly suited to Australian soils with low nutrient availability. Using a simulation model to develop computer-aided design of 3-D root structure and function, tailored to particular environments, this project will enhance breeding for increased nutrient-use efficiency.
Tailoring physiologically-based nanomaterial fertilisers for the biofortification of zinc in broadacre crops. Soil zinc deficiency is a global issue causing low crop yield and malnutrition. This project will develop a new class of fertiliser formulations by combining advanced chemistry techniques with plant physiology knowledge and nanomaterial manufacturing. These products will be designed for enhanced agronomic efficiency and environmental safety.
Engineered graphene-based nanofertilizers to improve crop nutrition. This project seeks to evaluate the unique properties of graphene to more effectively engineer novel fertilizers with properties that can enhance nutrient efficiency and reduce losses to the environment. More efficient and effective fertilizer formulations are needed to improve nutrient use efficiency in agricultural systems globally, and for effective biofortification of staple food crops with essential micronutrients.

More efficient and effective fertilizer formulations are needed to improve nutrient use efficiency in agricultural systems globally, and for effective biofortification of staple food crops with essential micronutrients. Nitrogen may be lost from soil through leaching and gaseous losses to the atmosphere. Phosphorus, as well as copper, manganese and zinc, are prone to reactions in soils and during manufacturing which reduces their effectiveness.Read moreRead less
Carbon costs of plant nutrient and water uptake. This project aims to investigate how much carbon plants need to invest belowground in return for water and nutrients. By using economic principles of supply and demand the project will quantify carbon expenditure for water and nutrients in grasslands and crops under different climate and land management scenarios.

This project aims to investigate how much carbon plants need to invest belowground in return for water and nutrients. By using economic principles of supply and demand the project will quantify carbon expenditure for water and nutrients in grasslands and crops under different climate and land management scenarios. This project will use triple and quadruple isotope labelling techniques and explore the dependency of carbon investment on plant-microbial interactions and availability of belowground resources. Expected outcomes include new knowledge to build a universal framework about plant carbon-water-nutrient economics. This will benefit global carbon cycling models and efforts to increase nutrient and water use efficiencies in agricultural crops.Read moreRead less

This project aims to generate bread containing high amounts of biologically available iron through targeted manipulation of plant-derived phytonutrients at several points along the wheat-to-bread supply chain. The project expects to generate new knowledge for developing healthier bread and address consumer demands for value-added food products. Anticipated outcomes are novel plant breeding and food manufacturing techniques that enhance the nutritional composition of wheat grain and bread making products, resulting in higher-value agricultural commodities and breads. The project should benefit bread retailers and crop growers involved in Australia’s $4.7 billion bread market and reduce the environmental impacts of bread production.Read moreRead less
