roGFP fluorescence in flowers (pistil, anther, and germinated pollen) (stage 14) on germination medium. The first column shows fluorescence resulting from excitation at 405 nm, the second shows fluorescence resulting from excitation at 488 nm, and the last column shows the ratio of fluorescence at 405/488 nm. PG, pollen grain; PT, pollen tube; SP, stigmatic papillae.
