Improving the ability of crops to use water, light and fertiliser more efficiently would have economic benefits and ease the environmental impacts associated with agricultural practices. It is thought that such improvements can be made by enhancing the efficiency of the photosynthetic protein, Rubisco, which fixes most of the CO2 in the biosphere. The research proposed here uses unique Rubisco transplantation capabilities that I have developed to improve our fundamental understanding of how Rubisco is processed and its activity regulated in plants. This will pave the way for our ongoing efforts to engineer and transplant more efficient Rubisco into crops.Read moreRead less

New technologies will be developed to save time, money and effort in rapid preparation of protein samples for structural genomics. Systems will be devised for preparing sufficient isotope-labelled proteins for nuclear magnetic resonance spectroscopy without using living organisms, for efficiently identifying points at which proteins can be broken into smaller fragments with the right properties, and for joining the ends of proteins and peptides together to make them much more stable. This combination of technologies are widely applicable to current problems in protein chemistry, molecular biology, functional genomics and the medical sciences.Read moreRead less
Developing an Essential Research Platform for the Molecular Engineering of Photosystem II. Sunlight reaching the earth is used by plants and algae to drive photosynthesis and to store chemical energy. Possibly the most fundamental contribution photosynthesis makes to earth is to generate gaseous oxygen, the result of solar driven water-splitting chemistry. However, the mechanism behind water-splitting is not exactly known. In this proposal we will construct a new model cyanobacteria host to stu ....Developing an Essential Research Platform for the Molecular Engineering of Photosystem II. Sunlight reaching the earth is used by plants and algae to drive photosynthesis and to store chemical energy. Possibly the most fundamental contribution photosynthesis makes to earth is to generate gaseous oxygen, the result of solar driven water-splitting chemistry. However, the mechanism behind water-splitting is not exactly known. In this proposal we will construct a new model cyanobacteria host to study water splitting. The host organism will be genetically modified to enable mechanistic questions of water oxidation to be tested and will provide new and pure forms of isolated protein. This model organism will provide team of international researchers with a remarkable tool new to study photosynthesis.Read moreRead less
Mechanism of higher-order chromatin formation and its role in controlling gene expression. The organization of genomic DNA into chromatin has solved one of the most difficult engineering problems required for the development of a multicellular organism; the compaction of over two meters DNA into a cell almost one millionth this size. Importantly, this compaction of the genome into chromatin has also been exploited by the cell to regulate the expression of genes. The aim of this investigation is ....Mechanism of higher-order chromatin formation and its role in controlling gene expression. The organization of genomic DNA into chromatin has solved one of the most difficult engineering problems required for the development of a multicellular organism; the compaction of over two meters DNA into a cell almost one millionth this size. Importantly, this compaction of the genome into chromatin has also been exploited by the cell to regulate the expression of genes. The aim of this investigation is to elucidate how genes are assembled into complex active or inactive chromatin structures by employing a novel in vitro system. This information will have important implications for gene therapy strategies.

The Dynamic Control of Chromatin Structure. A human chromosome is a highly heterogeneous global structure because along its axis, it folds to different extents to form either highly compacted domains that repress the expression of genes or less condensed regions that enable genes to be turned on. Changes to the structure or stability of chromosomes, and the corresponding alterations to gene expression, have been linked to many diseases states like defects in human development and cancer. This s ....The Dynamic Control of Chromatin Structure. A human chromosome is a highly heterogeneous global structure because along its axis, it folds to different extents to form either highly compacted domains that repress the expression of genes or less condensed regions that enable genes to be turned on. Changes to the structure or stability of chromosomes, and the corresponding alterations to gene expression, have been linked to many diseases states like defects in human development and cancer. This study will uncover the underpinning mechanism of how our chromosomes are organised into distinct functional domains, which may offer the potential to develop new strategies to correct chromosomal abnormalities.

Evolvability and the Evolution of Complexity. Anyone engaging in a moment's reflection on the striking richness, diversity, and complexity of the biological world is faced with the question: how did it get here? Though natural selection is central to answering this question, important new work has identified various conditions that make some lineages of organisms "evolvable": capable of changing in ways that radically expand the range of further possible changes. This project will clarify and in ....Evolvability and the Evolution of Complexity. Anyone engaging in a moment's reflection on the striking richness, diversity, and complexity of the biological world is faced with the question: how did it get here? Though natural selection is central to answering this question, important new work has identified various conditions that make some lineages of organisms "evolvable": capable of changing in ways that radically expand the range of further possible changes. This project will clarify and integrate these various conditions using empirical examples and simple models. The resulting work from this project will provide a clearer general understanding of what biological complexity is, and how science has compelling candidates for understanding how it evolves.Read moreRead less
