| Research Abstract |
We developed the imaging technique using a confocal microscopy to observed photosynthetic proteins in live plant cells. Using a moss Physcomitrella patens, whose rate of homologous recombination of the nuclear genes is extremely high, we fused a green fluorescent protein (GFP) to the C-terminal region of LHCB9, a moss specific light-harvesting antenna protein. As a result, we visualized the LHCB9-GFP in the giant chloroplast thylakoid membranes in live plant cells for the first time. The results obtained here will be useful for the visualization of other important proteins related to the light energy transfer in chloroplast thylakoid membranes.
