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.
New approaches for screening cereal germplasm for enhanced microbial pathogen resistance and desirable grain texture. The trait of grain hardness (texture) is of significance to the Australian infrastructure, as exports of hard wheat contribute over 5 billion dollars per year on average to the national economy and hard wheats are also important for domestic usage. The genes responsible for grain texture also impart resistance to bacterial and fungal pathogens which can cause extensive damage. ....New approaches for screening cereal germplasm for enhanced microbial pathogen resistance and desirable grain texture. The trait of grain hardness (texture) is of significance to the Australian infrastructure, as exports of hard wheat contribute over 5 billion dollars per year on average to the national economy and hard wheats are also important for domestic usage. The genes responsible for grain texture also impart resistance to bacterial and fungal pathogens which can cause extensive damage. However, the Australian gene pool has very limited genetic diversity in grain textures and thus possibly in pathogen resistance. The project will work out the science behind these two traits and identify lines with new variants of textures and pathogen resistances, thus greatly benefiting the national infrastructure and local primary industries.Read moreRead less
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

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 ....Factors causing wheat stripe rust epidemics.

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
Cellulose-based composites as models for primary plant cell walls of cereals and grasses. Cereals and grasses are the lynchpins of the Australian Agri-Food industry. Cell walls provide shape, form and barrier properties to the plant and are the basis for both post-harvest mechanical properties and direct nutritional benefits. There is as yet no validated model for the molecular assembly, architecture and mechanical behaviour of cereal/grass cell walls. This project aims to derive such a model, s ....Cellulose-based composites as models for primary plant cell walls of cereals and grasses. Cereals and grasses are the lynchpins of the Australian Agri-Food industry. Cell walls provide shape, form and barrier properties to the plant and are the basis for both post-harvest mechanical properties and direct nutritional benefits. There is as yet no validated model for the molecular assembly, architecture and mechanical behaviour of cereal/grass cell walls. This project aims to derive such a model, so that predictions can be made concerning the effects of tailoring either plant composition (e.g. at the gene level) or post-harvest treatment in order to achieve desired plant or food properties. The findings will also be relevant to understanding how individual features of cell walls affect digestibility and nutritional properties.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
