Caption: The image shows two pollen grains viewed by fluorescence microscopy. A pair of red sperm cells are visible in the normal pollen grain (top left) whilst only one red germ cell is present in mutant pollen (bottom right). The sperm cells are visualized using the monomeric red fluorescent protein mRFP1 derived from a coral species.
