A novel role for phytochrome in dormancy release inhibition. Seed dormancy contributes to the persistence of weeds in agriculture by enabling seeds to remain viable in the soil for many years, and is a major reason why annual ryegrass (Lolium rigidum) has become the most economically damaging weed in Australian agriculture. Recently we discovered a new way to control dormancy release and germination in these seeds. This project to identify the changes occurring within the seeds during dormancy r ....A novel role for phytochrome in dormancy release inhibition. Seed dormancy contributes to the persistence of weeds in agriculture by enabling seeds to remain viable in the soil for many years, and is a major reason why annual ryegrass (Lolium rigidum) has become the most economically damaging weed in Australian agriculture. Recently we discovered a new way to control dormancy release and germination in these seeds. This project to identify the changes occurring within the seeds during dormancy release will underpin our efforts to manipulate emergence timing in order to improve the efficacy of current weed control practices and contribute to sustainable farming systems.Read moreRead less

Summary
Enhancing resistance to wheat stripe rust disease. This project aims to investigate why wheat succumbs to stripe rust fungus, a grave threat to global wheat production. Wheat is the primary agricultural and revenue crop of Australia, cultivated since early European settlement. Severe disease epidemics arise when the fast evolving rust pathogen breaks down host plant genetic resistance. This project will investigate the molecular mechanisms of host-pathogen recognition and the consequences of pat ....Enhancing resistance to wheat stripe rust disease. This project aims to investigate why wheat succumbs to stripe rust fungus, a grave threat to global wheat production. Wheat is the primary agricultural and revenue crop of Australia, cultivated since early European settlement. Severe disease epidemics arise when the fast evolving rust pathogen breaks down host plant genetic resistance. This project will investigate the molecular mechanisms of host-pathogen recognition and the consequences of pathogen variation to determine the causes of resistance breakdown. The expected outcome is robust rust-resistant wheat cultivars to maintain global food security.Read moreRead less
Building better Brassicas: Understanding disease resistance mechanisms across the Brassicaceae. Brassica species are important crops producing cooking oil, vegetables and biofuel, grown in diverse environments with a high economic and export value. Blackleg disease, caused by the fungus Leptospheria maculans, is the most important disease of brassica crops world-wide. The newly available brassica genome sequence provides the resources to study the co-evolution of this plant and pathogen. This pr ....Building better Brassicas: Understanding disease resistance mechanisms across the Brassicaceae. Brassica species are important crops producing cooking oil, vegetables and biofuel, grown in diverse environments with a high economic and export value. Blackleg disease, caused by the fungus Leptospheria maculans, is the most important disease of brassica crops world-wide. The newly available brassica genome sequence provides the resources to study the co-evolution of this plant and pathogen. This project will characterise the evolution and conservation of resistance genes in wild and cultivated brassicas, using next-generation sequencing technology, to assess their potential for crop improvement. An understanding of the evolution of genes responsible for resistance will lead to improved plant protection strategies for brassica crops.Read moreRead less
Mediator: a new concept for controlled gene expression in plant biotechnology. The Mediator protein complex is a new control point for the activation of all genes in higher organisms and the purpose of this project is to understand how three Mediator subunits regulate disease resistance in plants. The outcomes provide a new concept to direct natural gene expression towards robust crop plants able to cope with climatic variations.
Deciphering the role of microRNAs during pathogen attack: new concepts for disease resistance in plants. Small non-coding RNAs called ‘microRNAs’ regulate diverse pathways in plants including plant defence against pathogens. This project will investigate the roles of plant microRNAs in response to four economically important viruses and compare these to a bacterial and a fungal pathogen. The aim is to dissect the underlying molecular mechanism of microRNA-based gene regulation during pathogen in ....Deciphering the role of microRNAs during pathogen attack: new concepts for disease resistance in plants. Small non-coding RNAs called ‘microRNAs’ regulate diverse pathways in plants including plant defence against pathogens. This project will investigate the roles of plant microRNAs in response to four economically important viruses and compare these to a bacterial and a fungal pathogen. The aim is to dissect the underlying molecular mechanism of microRNA-based gene regulation during pathogen infection and specifically identify common microRNAs which have evident impact during virus attack. This study is crucial due to its focus on virus diseases that cause severe damage to many crop plants; a global issue with strong implications for food security. This project is expected to provide basic new concepts for disease resistance in plants.Read moreRead less
Genomic strategies for reducing losses during processing and improving the nutritional value of wheat in human diets. Wheat breeding requires efficient tools to allow selection of varieties with both high grain yield and good functional and nutritional value. Whole genome analysis will be used to develop screening methods to deliver wheat varieties with novel processing and nutritional properties for human diets contributing to global food and nutritional security.
Novel oxygen sensing tools for monitoring the effects of dredging on Australian seagrass communities. Seagrass meadows sustain marine biodiversity and the fishing industries on Australian coasts. Dredging of ports and shipping channels is contributing to their rapid global decline. The project will use state-of-the-art technologies in bio-optics and genomics to create a toolkit for seagrass managers to make informed decisions to safeguard seagrass meadows.
Interactive effects of salinity and nutrients: linking physiological processes with patterns in mangrove forest productivity.

The proposed research will provide insight into physiological mechanisms that underpin mangrove productivity along salinity and aridity gradients, and determine how these factors affect plant responses to nutrient enrichment. Plant traits that increase salt and drought tolerance will be identified, thereby assisting development of plant varieties suited to Australian conditions. The results will also contribute to development of process-based models to better manage mangrove resources with climate change and increasing nutrient influx from urban or agricultural activities. Such models are essential for managing mangrove productivity for sustainable fisheries, and protecting the ecological well being of the coastal zone.Read moreRead less
