Confocal optical section of a living chlorenchyma cell (stained with the nucleic
acid stain acridine orange) of Bienertia cycloptera, which possesses
a novel mechanism for C4 photosynthesis. Enzymes and organelles are
partitioned into two separate compartments within a single chlorenchyma cell.
The nucleus (green) is juxtaposed between a large, central cytoplasmic compartment,
densely packed with chloroplasts (red autofluorescence), and a peripheral compartment
with uniformly distributed chloroplasts. The cover is dedicated to co-author,
Vincent Raymond Franceschi (1953-2005), who contributed to the discovery of
single-cell C4 photosynthesis.
