Targeting chloroplasts to enhance crop salt tolerance. Yield losses in crop plants due to increasingly saline soils are linked to the effects of salt on chloroplasts. By comparing chloroplast water- and salt-transport mechanisms of closely related salt-loving and salt-sensitive plants, this Fellowships aims to discover how chloroplasts maintain function in saline conditions. Novel biophysics and molecular techniques will be used to characterise transporters in model plants, and proof-of-concept ....Targeting chloroplasts to enhance crop salt tolerance. Yield losses in crop plants due to increasingly saline soils are linked to the effects of salt on chloroplasts. By comparing chloroplast water- and salt-transport mechanisms of closely related salt-loving and salt-sensitive plants, this Fellowships aims to discover how chloroplasts maintain function in saline conditions. Novel biophysics and molecular techniques will be used to characterise transporters in model plants, and proof-of-concept complementation experiments aim to confer salt tolerance on sensitive plants. These fundamental insights are likely to lead to rapid, step-change improvements in salt tolerance, especially in agriculturally relevant crops, to benefit Australia’s agri-industry and ensure food security in the future.Read moreRead less
Transport systems that underpin nitrogen efficient maize. This project aims to define the nitrogen transport network involved in the uptake, storage and redistribution of inorganic nitrogen (nitrate and ammonium) over the developmental life cycle of maize. This information will provide novel insight into the genetic control of nitrogen use in maize and other cereal crops.
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
Why is the peribacteroid membrane transcription factor SAT1 required for legume nitrogen fixation and what is its role in other symbiotic systems? This project will investigate the functional activity of the plant membrane bound basic helix-loop-helix (bHLH) transcription factor SAT1 in both nitrogen fixing (Rhizobia) and phosphorus acquiring (Arbuscular Mycorrhizal) symbioses found in plants. The project will identify its regulation and downstream activities across both symbiosis using selected ....Why is the peribacteroid membrane transcription factor SAT1 required for legume nitrogen fixation and what is its role in other symbiotic systems?

The project will identify its regulation and downstream activities across both symbiosis using selected legumes and or cereals.Read moreRead less
