Remodelling encapsulin nanocages to help enhance plant carbon fixation. Nature has evolved mechanisms in microbial systems to improve photosynthetic efficiency by saturating the enzyme Rubisco with carbon dioxide. These carbon concentrating mechanisms are genetically complex, precluding successful introduction into crops. Our simpler approach is to use encapsulins, a new source of robust bacterial pore-containing nanocages made from a single gene. This project will optimise the development of sy ....Remodelling encapsulin nanocages to help enhance plant carbon fixation. Nature has evolved mechanisms in microbial systems to improve photosynthetic efficiency by saturating the enzyme Rubisco with carbon dioxide. These carbon concentrating mechanisms are genetically complex, precluding successful introduction into crops. Our simpler approach is to use encapsulins, a new source of robust bacterial pore-containing nanocages made from a single gene. This project will optimise the development of synthetic encapsulin-Rubisco carbon-fixing nanoreactors and transform them into leaf chloroplasts to test their impact on plant photosynthesis and growth. Our genetically simpler solution will aid ongoing global efforts to deliver overdue step change improvements in agricultural productivity.Read moreRead less

This proposal aims to establish an Australian Advanced Metabolic Signal Discovery and Imaging platform. The platform consists of an ultra-high resolution gas chromatography mass spectrometer and an imaging mass spectrometry upgrade for a second existing high resolution mass spectrometer. The facility will break barriers currently limiting discovery and localisation of metabolic changes during plant and animal development under environmental stress; integral chemical signals exchanged in host-microbe interactions; and volatile signatures linked to ecosystem health and developmental anomalies in animals. Results will inform innovative strategies to enhance biological adaptation, climate resilience and plant, animal, and ecosystem health.Read moreRead less
Transcriptional and translational regulation of the neuronal protein tau. The microtubule-associated protein tau is important for brain development and performance. To perform these functions, tau levels and its variants are tightly controlled in brain cells. However, the factors that regulate tau remain largely unknown. This project will employ latest gene technologies to identify the molecular regulators of tau, for each step of the process from DNA to the protein. The outcome of this study wi ....Transcriptional and translational regulation of the neuronal protein tau. The microtubule-associated protein tau is important for brain development and performance.
