Abstract

We need a better understanding of cyanobacteria as physical systems, to complement the recent advances that have been made in their molecular biology. A combination of Fluorescence Recovery After Photobleaching (FRAP) and confocal microscopy will be used to investigate structure, membrane dynamics and diffusion in cyanobacteria. We will determine whether the thylakoid and plasma membranes are contiguous, and rates of diffusion in the cytoplasm and between the cytoplasm and the periplasm will be measured. The diffusion of markers between adjacent cells in filaments will be monitored, to test models for signalling during heterocyst development. We will generate mutants with elongated cells that will be suitable for FRAP measurements of membrane dynamics. This will allow genetic investigation of the factors determining the mobility of thylakoid membrane components.
