The identification of Mycosphaerella graminicola effectors that promote pathogenicity on wheat. Fungal diseases are one of the greatest challenges to sustainable wheat production in the 21st century. Septoria tritici blotch is one such disease as it inflicts millions of tonnes in yield losses per annum. This project will identify the molecular basis of Septoria tritici blotch and assess its potential as an Australian biosecurity threat.
Factors causing wheat stripe rust epidemics. This project aims to tackle wheat stripe rust, one of the most important fungal diseases of wheat in Australia, causing losses of up to $125 million a year. This project expects to gain insights into the fungal evolution and the molecular mechanism that causes hyper-virulent pathogen isolates. The expected outcome is to identify and characterise multiple genetic factors in the pathogen that contribute to wheat stripe rust epidemics in Australia.

This project expects to gain insights into the fungal evolution and the molecular mechanism that causes hyper-virulent pathogen isolates. The expected outcome is to identify and characterise multiple genetic factors in the pathogen that contribute to wheat stripe rust epidemics in Australia. This project will contribute to improved disease management strategies to contain wheat stripe rust, resulting in higher wheat yields, reduced application of fungicides and increased revenue for Australian wheat farmers.Read moreRead less

Uncovering how rust fungi cause devastating plant diseases. This project aims to generate a new understanding of how rust fungi infect plant cells using single-cell sequencing technologies and data-driven investigations. This project expects to discover conserved rust infection strategies and the first characterisations of mechanisms that transfer virulence proteins from the fungus to the plant.

This project aims to generate a new understanding of how rust fungi infect plant cells using single-cell sequencing technologies and data-driven investigations. This project expects to discover conserved rust infection strategies and the first characterisations of mechanisms that transfer virulence proteins from the fungus to the plant. Innovations and new knowledge from this project will be of high-impact and of benefit to the Australian and international community through knowledge discovery about conserved rust infection mechanisms. This project expects to deliver strategies for effective rust disease management that will in the future lessen the impact of rust diseases on agriculture and natural ecosystems in Australia.Read moreRead less
The role of auxin in root organ specification - from symbiont to parasite. Sustainable agriculture in a changing climate depends on strategies to maximise crop performance and to minimise crop losses due to parasites. This project aims to identify genes and molecular mechanisms that symbiotic and parasitic microbes, which affect major crop plants, use to alter plant growth in a beneficial or detrimental way.
Molecular basis of synergy between PIs and defensins against fungi. The plant defensin nicotinamide adenine dinucleotide dehydrogenase subunit 1 (NaD1) has potent antifungal activity against agricultural and human pathogens and has potential in the treatment of serious diseases that affect crop production and human health. NaD1 has been found to permeabilise membranes and allows entry of other molecules into the fungal cytoplasm. While screening for molecules that enhance the activity of defensi ....Molecular basis of synergy between PIs and defensins against fungi. The plant defensin nicotinamide adenine dinucleotide dehydrogenase subunit 1 (NaD1) has potent antifungal activity against agricultural and human pathogens and has potential in the treatment of serious diseases that affect crop production and human health. NaD1 has been found to permeabilise membranes and allows entry of other molecules into the fungal cytoplasm. While screening for molecules that enhance the activity of defensins a number of proteinase inhibitors were identified that act synergistically with NaD1. This project aims to identify the molecular basis of this synergy which is expected to lead to better control of fungal diseases of crops and in humans.Read moreRead less
Determining how the soluble dietary fibre beta-glucan is made in cereals. This Project aims to define the molecular mechanisms that control the processes involved in the biosynthesis and regulation of mixed linkage glucan, a major soluble dietary fibre in the cell walls of cereal grains. Plant cell walls determine the quality of most plant-based products used in modern human societies, yet the regulatory mechanisms responsible for their modulation are not well understood. Key distinguishing feat ....Determining how the soluble dietary fibre beta-glucan is made in cereals.

Plant cell walls determine the quality of most plant-based products used in modern human societies, yet the regulatory mechanisms responsible for their modulation are not well understood. Key distinguishing features of the Project will be the international, integrative, and multidisciplinary approach towards addressing this major challenge in plant biology and the potential of the fundamental scientific discoveries to benefit end-users in the food, feed and beverage industries.Read moreRead less

Summary
Understanding how water-transporting vessels in plants are made. This project aims to understand how cytoskeleton-associated proteins underpin the formation of water-conducting vessels. Uncovering molecular mechanisms that lead to efficient water transport in plants opens up new avenues to address food and crop safety, particularly in times of environmental change.
Cell wall synthesis and regulation in Nicotiana pollen tubes, a model tip-growing cell with a simple wall. Cell walls of plants determine the quality of most plant-based products and represent the world's largest renewable carbon resource. This project will address current gaps in our knowledge of wall structure and function at the molecular, genetic and biochemical levels using the relatively simple walls of tobacco pollen tubes as a model.
Re-engineering rice root architecture to maximise water use efficiency. This project aims to discover gene networks responsible for producing deeper and more branched roots in rice plants. The roots of plants are the primary mechanism for absorbing water and nutrients from the soil. Manipulating roots to penetrate deeper with greater branching allows plants to thrive with less water and less nutrients. The project will identify key genes and proteins responsible for this process, and alter their ....Re-engineering rice root architecture to maximise water use efficiency.

The roots of plants are the primary mechanism for absorbing water and nutrients from the soil. Manipulating roots to penetrate deeper with greater branching allows plants to thrive with less water and less nutrients. The project will identify key genes and proteins responsible for this process, and alter their expression in order to assess the role of these regulatory elements in root development in rice plants. The project expects to provide new, more sustainable varieties of rice which will help provide enhanced food security.Read moreRead less

This project aims to discover how the functions of different proteins change as they age, and to define factors that dictate protein stability inside plants. This project will change protein turnover rates in plants by altering a regulator of this process to assess the role of this regulator in different plant developmental transitions. Expected outcomes include showing how protein abundance can be altered in plants for our future agricultural and biotechnology needs. This will provide significant benefits, such as discovering processes inside plant cells that maintain the quality of different kinds of proteins and propose how different kinds of proteins can be stabilised for plant biotechnology applications.Read moreRead less
