Molecular basis of rust infection and host plant resistance. Plant diseases threaten agricultural productivity in Australia, with rust fungi being a major problem for cereal grain production. This project will investigate molecular processes underlying the infection of plants by rust fungi and will provide basic knowledge for development of novel and durable disease resistance strategies.
How is the plant genome reactivated and controlled during seed germination? This project aims to determine the mechanisms by which plant genomes are regulated during seed germination. The genomes of cells in mature, inactive seeds are repressed, but later must be rapidly reactivated to allow the gene expression that drives early seedling growth and development. This project will study proteins that turn genes on and off, and how these interact with the structure of DNA, in order to understand ho ....How is the plant genome reactivated and controlled during seed germination? This project aims to determine the mechanisms by which plant genomes are regulated during seed germination. The genomes of cells in mature, inactive seeds are repressed, but later must be rapidly reactivated to allow the gene expression that drives early seedling growth and development. This project will study proteins that turn genes on and off, and how these interact with the structure of DNA, in order to understand how spatial and temporal patterns of gene expression are controlled. It will advance our understanding of genome regulatory programs controlling germination and growth, and how they vary between Arabidopsis and barley. This can improve our ability to manipulate seed behaviour which would benefit growers and producers. Read moreRead less
Mitochondrial Biogenesis and Signalling in Plants . This proposal aims to define the mechanisms of how mitochondrial growth and stress signalling interact and are regulated. Mitochondria are central machines in cells that use energy obtained through photosynthesis to drive growth and also play an important role in sensing and responding to non-optimal environmental growth conditions. As mitochondrial growth and stress signalling are antagonistic, growth is retarded when stress signalling is acti ....Mitochondrial Biogenesis and Signalling in Plants . This proposal aims to define the mechanisms of how mitochondrial growth and stress signalling interact and are regulated. Mitochondria are central machines in cells that use energy obtained through photosynthesis to drive growth and also play an important role in sensing and responding to non-optimal environmental growth conditions. As mitochondrial growth and stress signalling are antagonistic, growth is retarded when stress signalling is activated. Thus, the outcomes will be new knowledge and understanding of how plants balance growth and stress responses. This benefit of this knowledge and understanding is that it can be used to pursue novel avenues to optimise crop performance in changing and adverse environments.Read moreRead less
