ARC Future Fellowship - impacts of climate change on plant respiration
From 2009-2013, Owen Atkin held an ARC Future Fellowship to invesigate mitochondrial and intact tissue respiratory responses to drought and global warming scenarios. The research led to several papers (see below), with many of those studies forming the basis of future work within the ARC Centre of Excellence in Plant Energy Biology (2014-2021).
