Abstract

The aim is to understand the mechanism of stromule formation between chloroplasts and to determine the size limits for movement of proteins and nucleic acid from chloroplast to chloroplast via stromules. The presence of envelope membranes in the stromules will be examined with green fluorescent protein fusions to targeting sequences for the inner and outer envelope membranes in transgenic tobacco plants. The size limit for protein movement will be investigated using GFP fusions to stromal proteins, including subunits of Rubisco and ribosomes, and localised two-photon photobleaching. Movement of the nucleic acids will be examined following microinjection of fluorescent-labelled RNA and DNA into single chloroplasts. The possible involvement of an actin-based motor system will be examined biochemically.
