IDENTIFYING CONTROL ELEMENTS IN CHLOROPLAST GENE EXPRESSION. Energy from sunlight is captured by photosynthesis in plants, providing the basis for the terrestrial food chain. This process takes place in chloroplasts, subcellular structures that derived from photosynthetic bacteria a billion years ago.

This process takes place in chloroplasts, subcellular structures that derived from photosynthetic bacteria a billion years ago. Chloroplasts have their own DNA, containing genes encoding the most important photosynthetic proteins. This project aims to provide the world’s best resources for the study of chloroplast genes. In the process, we will discover how these important genes are regulated to provide photosynthetic proteins in the right amounts, in the right cells, at the right time. The knowledge and resources gained will facilitate improvement of photosynthetic function in future agricultural crops.Read moreRead less

Many plants and animals can alter their genetic information via RNA (ribonucleic acid) editing, a process that is often essential for the growth and development of the organism. This ability provides accurate control over gene expression and has great potential as a biotechnological tool in agriculture and medicine. RNA editing could be used to switch genes on or off in biotechnological production systems with an unprecedented degree of precision, or to correct genetic diseases. This project aims to understand two RNA editing pathways in plants, one of which is found nowhere else and likely to involve a novel enzymatic mechanism. We will use the understanding gained to develop novel RNA processing tools usable in any living organism.Read moreRead less

Summary
A synthetic biology approach for mining the secondary metabolomes of fungal phytopathogens. Synthetic biology approaches will be employed to identify the secondary metabolites produced by the two important wheat pathogens, Stagonospora nodorum and Mycosphaerella graminicola. This will lead to the discovery of novel chemicals and facilitate our understanding of the roles of secondary metabolites in wheat diseases.
Synthetic biology tools for just-in-time control of biosynthetic pathways. Synthetic biology enables sustainable synthesis of precious chemicals, ranging from drugs to biomaterials. Using microbes, high production levels are usually attained by overexpressing the genes that make the desired product, but this simple approach often fails for antibiotics and other compounds that are toxic to microbes.

Synthetic biology enables sustainable synthesis of precious chemicals, ranging from drugs to biomaterials. Using microbes, high production levels are usually attained by overexpressing the genes that make the desired product, but this simple approach often fails for antibiotics and other compounds that are toxic to microbes. Using synthetic biology this project builds genetic circuits enabling smart, just-in-time activation of target genes, which is pervasive in natural pathways. Using these circuits we will boost 1) the production of a valuable antibiotic and 2) calcite precipitation in self-healing concrete. This approach enables the biosynthesis of many other chemicals, leading to cleaner and greener bio-factories.Read moreRead less
