Mitochondrial function in plants and the role of metabolism is the energy efficiency of plants

Mitochondria undertake respiration which provides chemical energy from the oxidative degradation of organic and amino acids in plant cells. Their functions are highly integrated into the nitrogen, phosphorus and carbon metabolism of plants and are directly involved in the abiotic and biotic stress tolerance of plants.

Professor Millar’s research has provided key new insights into antioxidant defence pathways in mitochondrial, diurnal rhythms in mitochondrial metabolism, tissue-specific mitochondrial functions, plant-specific features of the electron transport chain, regulatory networks governing respiratory activity in plants, and the mechanisms of mitochondria damage during oxidative stress. The Millar research group also currently working on advances in plant proteome analysis to allow measurements of protein turnover rates and targeted quantitation of enzymes in metabolic pathways in both model plants and crops. In international collaborations using novel dataset and software developments, they have been involved in building plant proteome databases, protein location prediction and protein-protein interaction prediction in plants.
