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.

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
Unique plant hormone responses: the key to nitrogen-fixing nodules. This project aims to build a model of the signals that regulate root nodule formation, unique root organs formed by some plants that host nitrogen-fixing bacteria. Nitrogen is often limited in the soil and agriculture relies on nitrogen fertiliser. Sustainable sources of plant nutrients are required to ensure food security and minimise the environmental impact of intensive farming. This project will provide fundamental informati ....Unique plant hormone responses: the key to nitrogen-fixing nodules. This project aims to build a model of the signals that regulate root nodule formation, unique root organs formed by some plants that host nitrogen-fixing bacteria. Nitrogen is often limited in the soil and agriculture relies on nitrogen fertiliser. Sustainable sources of plant nutrients are required to ensure food security and minimise the environmental impact of intensive farming. This project will provide fundamental information on why some species can form nitrogen-fixing nodules by examining the role of plant hormones. This will build the knowledge base required to potentially expand this symbiosis into non-legumes, harnessing the huge advantage nodule forming species have in staple crops.Read moreRead less
Genetic control of flowering in legumes. Flowering in plants is strongly regulated by environmental factors, with important consequences for their natural distribution and use in agriculture. This project will isolate genes, characterize genetic diversity and dissect molecular mechanisms that regulate flowering, contributing to fundamental biology, crop improvement and research training.
