Identifying the diversity and evolution of loci associated with adaptation to aridity/heat and salinity in ancient cereal crops. This project will use ancient grains of wheat, barley and rye to find 'lost' genetic diversity at key genes associated with resistance to aridity, salt and disease. This project will make the proteins of key genes, and study their interaction with the environment over time by measuring ions in the grains to reveal the ancient environmental conditions.
How common and what is the significance of cis-acting regulatory variation and genomic imprinting in plants? Plant based processes provide truly sustainable solutions to many of the challenges facing Australia. The proposed research will help elucidate how plants regulate variation in gene expression rather than changes in the structure of encoded proteins. This is an area of gene expression, that has not been approached before, that explains the plant's ability to respond to external stimuli. ....How common and what is the significance of cis-acting regulatory variation and genomic imprinting in plants? Plant based processes provide truly sustainable solutions to many of the challenges facing Australia. The proposed research will help elucidate how plants regulate variation in gene expression rather than changes in the structure of encoded proteins. This is an area of gene expression, that has not been approached before, that explains the plant's ability to respond to external stimuli. Variation between plant species in the number of genes does not fully explain the differences between them. This information will come not from seqenceing genomes but from investigation of regulatory elements. Read moreRead less
Microgenomics - a tool to dissect effects of salinity on gene expression in specific cell types of Arabidopsis and rice. This project will provide novel, fundamental understanding of the cell type-specific processes involved in salinity tolerance in higher plants. As such, it will impact on our understanding of a range of processes relevant to salinity tolerance, an area of great importance to Australian agriculture and environmental sustainability.

Harnessing Mendel’s workhorse: meiotic crossovers for genetic diversity in crop breeding. Introducing genetic diversity from wild species into elite lines of wheat and barley may increase their resistance to the stresses they are exposed to in the field. Modern breeding cultivars could capture up to ten times more genetic variation. This project aims to gain fundamental insights into the genetic and environmental factors that limit the rates at which new genomic combinations can be made. This wi ....Harnessing Mendel’s workhorse: meiotic crossovers for genetic diversity in crop breeding. Introducing genetic diversity from wild species into elite lines of wheat and barley may increase their resistance to the stresses they are exposed to in the field. Modern breeding cultivars could capture up to ten times more genetic variation. This project aims to gain fundamental insights into the genetic and environmental factors that limit the rates at which new genomic combinations can be made. This will transform wheat and barley breeding methods, unlocking available genetic diversity to produce new varieties. Read moreRead less
Reconstructing wheat evolution using ancient DNA. The domestication of wild grasses by farmers was a step change in human history; it led to the emergence of modern cereals and with them, western civilisation. This project will apply modern DNA sequencing methods to 5000-year-old cereal seeds to reconstruct the history of wheat, barley and other crops, and identify lost ancient forms and diversity.

Plant genomics has direct benefit to crop improvement, especially as focussed in the applicants' laboratories. Thus, the Australian agri-food sector will benefit substantially from the acceleration in plant functional genomics that will arise from the installation of the robotics equipment described in the current application, by both underpinning more applied research and also being used directly in crop improvement programs such as are based at the Waite Campus. The outputs will include crops with increased tolerance to biotic and abiotic stresses, a reduced dependence on chemical inputs such as fertilisers and improved food quality, with consequent benefits to the environment and human health and nutrition.Read moreRead less
The genetic and molecular organisation of the self incompatibility gene region in the grasses. Self-incompatibility (SI) is a cell-cell recognition process used by plants to prevent self-pollination and force outcrossing. It is widespread, occurring in a third of plant families. Although studies of SI go back to the 1800s, the origin of SI remains a mystery. Recent advances in the molecular characterisation of SI loci in some species has re-ignited debate on its origins but has provided few answ ....The genetic and molecular organisation of the self incompatibility gene region in the grasses.

Although studies of SI go back to the 1800s, the origin of SI remains a mystery. Recent advances in the molecular characterisation of SI loci in some species has re-ignited debate on its origins but has provided few answers. This project uses the grasses to explore the origins of SI. As a model system, the grasses offer detailed genetic and molecular data and aspects of floral architecture associated with SI can be investigatedRead moreRead less

Control points in nitrogen uptake: enhancing the response of cereals to nitrogen supply and demand. Vast amounts of nitrogen fertiliser are applied to cereal crops to maintain yields. By uncovering what limits nitrogen uptake in cereals, this project will provide the scientific basis for improving nitrogen use efficiency and decreasing fertiliser use, with significant economic and environmental benefits.
Reduced Water Consumption in Commercial Malting Processes. The successful outcome for the project will be the production of barley varieties that can be successfully malted with a single steep, rather than the conventional two steeps currently employed. The objective will be achieved through the reduction of cell wall beta-glucan in barley grain. This will result in water savings of around 40%, or 1,500 megalitres per annum, for the Australian malting industry. The 1,500 megalitres saving in ....Reduced Water Consumption in Commercial Malting Processes.

This will result in water savings of around 40%, or 1,500 megalitres per annum, for the Australian malting industry. The 1,500 megalitres saving in water use would be sufficient to support the domestic water consumption of 30,000 people, based upon the use of 140 litres per person per day that was recently achieved in Brisbane.Read moreRead less
