Discovery of new genes for plant cellulose biosynthesis and improved fibre production. Cellulose, the world's most abundant biopolymer, is important to the cotton and forest industries and for human and animal nutrition. Before biotechnology can manipulate cellulose, we must identify the enzymes of the synthesis pathway and understand how their properties determine the properties of the cellulose they produce. Not all enzymes are known and any relationships to cellulose properties remain unexplo ....Discovery of new genes for plant cellulose biosynthesis and improved fibre production. Cellulose, the world's most abundant biopolymer, is important to the cotton and forest industries and for human and animal nutrition. Before biotechnology can manipulate cellulose, we must identify the enzymes of the synthesis pathway and understand how their properties determine the properties of the cellulose they produce. Not all enzymes are known and any relationships to cellulose properties remain unexplored. This study extends our successful mutational analysis of cellulose synthesis in Arabidopsis and initiates the molecular analysis of organisms making cellulose with distinctive properties. It will significantly advance knowledge of cellulose biosynthesis and identify novel genes for fibre improvement.Read moreRead less
Taming the intruders: the domestication of Tigger transposable elements in mammals. It has become apparent that most of the DNA that makes us what we are is actually comprised of the remnants of invading parasitic DNA acquired over time. A continual battle exists between host which tries to silence or remove this DNA, and the parasite that tries to multiply and spread. We are currently investigating an intriguing aspect of this process that involves host genomes 'domesticating' parasitic DNA to ....Taming the intruders: the domestication of Tigger transposable elements in mammals.

This project aims at combining molecular genetics, transcriptome and proteome analysis to identify genes and pathways underlying high light stress tolerance in previously isolated mutants of the chlorophyte Chlamydomonas reinhardtii. Comprehensive profiles of transcriptome-proteome linkage will be constructed without the complications of multicellularity for this unicellular photosynthetic model organism. We will establish a public proteome reference database and provide new microarrays and molecular markers beneficial for research in Chlamydomonas. We expect to advance understanding of high light resistance mechanisms so that it will eventually be applicable to improve productivity in crop plants growing under various environmental stress conditions.Read moreRead less
Flipping the mattress: infinite polyurethane recycling by synthetic biology. Australia is covered in billions of tonnes of plastic and yet <10% is recycled today. Polyurethane (PU) is ubiquitous in our everyday lives, from lacquer coatings to elastane clothing to durable foam padding in car seats, cushions and mattresses. Currently, there are few avenues for PU recycling and much ends up in landfill e.g., a single mattress produces 15-20kg of PU foam waste. Luckily, biodegradation of PU can occu ....Flipping the mattress: infinite polyurethane recycling by synthetic biology. Australia is covered in billions of tonnes of plastic and yet <10% is recycled today. Polyurethane (PU) is ubiquitous in our everyday lives, from lacquer coatings to elastane clothing to durable foam padding in car seats, cushions and mattresses. Currently, there are few avenues for PU recycling and much ends up in landfill e.g., a single mattress produces 15-20kg of PU foam waste. Luckily, biodegradation of PU can occur naturally via various microbial means and from insects, like Galleria mellonella larvae. The overall aim of this research project is to understand plastic biodegradation and translate nature’s solutions into flexible and efficient synthetic enzyme technologies that can sustainably recycle commonly used PU foams.

Role of mRNA polyadenylation control in gene expression. Several benefits would come from a more complete understanding of the function of the messenger RNA poly(A) tail. It is frequently targeted by mechanisms that control cellular protein synthesis. This is most evident in developmental biology, where tail length control regulates maternal mRNA expression. Our previous work suggests that it has much wider importance for cellular function than previously thought and thus its study will produce ....Role of mRNA polyadenylation control in gene expression.

This is most evident in developmental biology, where tail length control regulates maternal mRNA expression. Our previous work suggests that it has much wider importance for cellular function than previously thought and thus its study will produce knowledge of broad relevance to modern life sciences and its applications in medicine and biotechnology. Finally, a better understanding of yeast cellular biology is of benefit to the food and biotechnology sector of industry.Read moreRead less
TraitCapture: Genomic modelling for plant phenomics under environmental stress. This project aims to develop software to integrate new hyper-spectral and 3D growth models of plant phenomics with population genomics to identify heritable developmental traits across varied environments. Genome wide association studies aim to then be used to identify causal genes. Functional structural plant models incorporating genetic variation will be used to predict growth under simulated stress environments. ....TraitCapture: Genomic modelling for plant phenomics under environmental stress.

Genome wide association studies aim to then be used to identify causal genes. Functional structural plant models incorporating genetic variation will be used to predict growth under simulated stress environments. The research team unites international industry, the Australian Plant Phenomics Facility, and university statistical geneticists.

Epigenetic reprogramming of development by nutritional factors in honeybee. The project aims to study the mechanism by which a specialised nutrition can change or even reverse the process of adult cell fate. The project will use a previously unexplored method of nutritional reprogramming of imaginal discs in honeybees by royal jelly and identify novel components of both the genetic and epigenetic systems that are most potent as reprogramming factors.

The project aims to study the mechanism by which a specialised nutrition can change or even reverse the process of adult cell fate. The project will use a previously unexplored method of nutritional reprogramming of imaginal discs in honeybees by royal jelly and identify novel components of both the genetic and epigenetic systems that are most potent as reprogramming factors. The project seeks to improve our understanding of how epigenetic remodelling of the information content of the genome contributes to conversion of cell fate in vivo and in vitro. More broadly, the project could potentially establish the honeybee imaginal discs as a model for understanding pluripotency and environmentally controlled developmental plasticity.Read moreRead less
