How is organelle function regulated by environmental cues and affected by abiotic stress?
Employing the diverse and cutting-edge technology platforms available at the Centre, we are able to undertake the measurement of changes in the key plant energy processes of photosynthesis, respiration and photorespiration in response to environmental signals such as changes in light, water availablility and temperature. Arabidopsis plants with defined mutations or having phenotypes indicative of stress phenomena are being generated and analysed at multiple molecular levels, using our technologies to identify: • alterations in gene transcription • changes in the organelle proteomes, notably the detection of proteins damaged or modified in response to stresses • altered metabolite fluxes and induction of novel metabolites • shifts in targeted cellular processes such as photosynthesis, mitochondrial electron transport and production of protective antioxidants. These data will be integrated with relevant data from the Centre’s organelle biogenesis and metabolomics discovery activities, an
