Abstract

The processes contributing to oxidative stress, and associated tolerance mechanisms in algae and plants, are currently attracting much attention, whether in terms of ecological responses or underlying molecular mechanisms. Critically, measurement of contributory gross fluxes of oxygen cannot be undertaken using conventional gas analysers or electrodes since it is not possible to distinguish internal sources and sinks operating simultaneously in the light. The aim of this proposal is to establish a mass spectrometric facility to allow analysis of gaseous exchange across sections of intact leaves, organs or purified enzymes which will provide a focus for research in physiological ecology within the UK and Northern Europe. The Facility, to be based in the Department of Plant Sciences, University of Cambridge will be founded on a programme of ongoing research within that Department, which is analysing the ecological interactions between contrasting plant lifeforms, their impact on gaseous exchange and convergent evolution in the primary carboxylase, Rubisco. In addition, the Facility will attract visiting research staff and students from Universities and Research Institutes throughout the UK, many of whom have submitted research proposals in support of this application.
