Crystal Structure of a Multilayer Packed Major Light-Harvesting Complex： Implications for Grana Stacking in Higher Plants

Dear Editor, Grana thylakoids in plants comprise multiple, tightly appressed thylakoid membranes in the chloroplast, which greatly increase the area-to-volume ratio and significantly improve the ability of chloroplasts to capture light. Grana layers are stacked and interact through the stromal surface of proteins embedded in the grana membranes,
