Methane is an extremely potent greenhouse gas. Recent evidence suggests that tree-mediated fluxes may be a significant, but overlooked source of methane to the atmosphere. This project aims to quantify the magnitude and drivers of tree-mediated methane fluxes from Australia’s dominant forest types. Innovatively, we will be using a novel combination of empirical field based measurements, gas tracer experiments, microbial analysis and modelling methods. Expected outcomes are a mechanistic understanding of tree-mediated methane fluxes, helping to constrain regional, national and global methane budgets. The results of this study will help inform publicly funded greenhouse gas abatement strategies, ensuring a maximal return on investment.Read moreRead less
Deciphering organelle transport mechanisms in plants. Plant growth, productivity and seed yield all depend on organelle function which requires metabolites and proteins
to be transported across membranes. This mechanism of transport is carried out by specific transporters that have
the ability to transport macromolecules, and regulate organelle function. We have identified new transporters that
are involved in amino acid and protein transport in the mitochondria, chloroplast and peroxisomes. We ....Deciphering organelle transport mechanisms in plants. Plant growth, productivity and seed yield all depend on organelle function which requires metabolites and proteins
to be transported across membranes. This mechanism of transport is carried out by specific transporters that have
the ability to transport macromolecules, and regulate organelle function. We have identified new transporters that
are involved in amino acid and protein transport in the mitochondria, chloroplast and peroxisomes. We will assign
function to each protein and investigate the importance in regulating organelle biogenesis. This will allow us to
modulate plant energy production for optimal growth and to withstand abiotic stress, all of which have
agriculturally beneficial consequences. Read moreRead less
