The cell wall substrate delivery mechanisms in plants. This project aims to study the delivery of substrates plants need to biosynthesise sugar polymers. Sugar polymers play key structural and functional roles in plant development and determine quality for all plant-based products including food, textile fibres, building materials and renewable biomass. However, unknown mechanisms regulate and control the transport mechanisms that deliver the building blocks for polysaccharide biosynthesis.

Sugar polymers play key structural and functional roles in plant development and determine quality for all plant-based products including food, textile fibres, building materials and renewable biomass. However, unknown mechanisms regulate and control the transport mechanisms that deliver the building blocks for polysaccharide biosynthesis. This project is expected to increase understanding of nucleotide sugar transport and develop and enhance the biological toolbox for applications involving modelling and engineering of plants, synthesis of industrial biopolymers and production of functional foods.Read moreRead less

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.

This project is part of the National Priorities "Frontier Technologies for Building and Transforming Australian Industries." Using innovative plant metabolic engineering technologies combined with sophisticated computer modeling we are generating green plants that produce renewable, biodegradable, bioplastics possessing properties such that they are suitable replacements for petroleum-derived products in many applications. During the course of these studies, we are increasing our basic level of understanding of plant metabolism of important bioenergy crops. The production of renewable, bioplastics in sugarcane will help to diversify the Australian sugarcane industry by providing a value-added product with significant world-wide markets.Read moreRead less

How do effector proteins from necrotrophic fungi cause disease in plants? This project aims to develop new knowledge to support the development of strategies to protect wheat from necrotrophic fungi. Crop losses caused by plant diseases are a significant economic, environmental and social challenge in a world facing increased demands on food, fibre and biofuels. Parastagonospora nodorum is an economically important necrotrophic fungal pathogen of wheat.

This project aims to develop new knowledge to support the development of strategies to protect wheat from necrotrophic fungi. Crop losses caused by plant diseases are a significant economic, environmental and social challenge in a world facing increased demands on food, fibre and biofuels. Parastagonospora nodorum is an economically important necrotrophic fungal pathogen of wheat. During infection, P. nodorum uses effector proteins to target sensitivity gene products in wheat. This process, known as necrotrophic effector-triggered susceptibility, results in plant cell death and disease. This project aims to investigate the structural basis of necrotrophic effector-triggered susceptibility in the P. nodorum – wheat pathosystem.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

Abiotic stress tolerance of cellulose synthesis in Arabidopsis. This project aims to delineate how two components, that are part of a protein-complex, synthesise cellulose and protect the complex against environmental stress function. Also, it aims to identify co-factors that assist in cellulose synthesis and microfibril assembly. Sustainable resources for fuel, food and feed are needed and plant biomass, largely consisting of cellulose, offers a great raw material for this purpose. However, our ....Abiotic stress tolerance of cellulose synthesis in Arabidopsis. This project aims to delineate how two components, that are part of a protein-complex, synthesise cellulose and protect the complex against environmental stress function. Also, it aims to identify co-factors that assist in cellulose synthesis and microfibril assembly. Sustainable resources for fuel, food and feed are needed and plant biomass, largely consisting of cellulose, offers a great raw material for this purpose. However, our understanding of how cellulose is synthesised is rudimentary. The results of this project could contribute towards tailoring cellulose production for industrial applications and for sustained biomass production.Read moreRead less
