Fluorescence microscopic images of <i>Acropora tenuis</i> polyps associated with clade C1 or D <i>Symbiodinium</i> algae, and aposymbiotic polyps 20, 58, and 80 days after inoculation. Ikuko Yuyama Tomihiko Higuchi 10.1371/journal.pone.0098999.g003 https://plos.figshare.com/articles/figure/_Fluorescence_microscopic_images_of_Acropora_tenuis_polyps_associated_with_clade_C1_or_D_Symbiodinium_algae_and_aposymbiotic_polyps_20_58_and_80_days_after_inoculation_/1052258 <p>Bright green fluorescence can be seen in the body walls and tentacles of polyps associated with clade C1 algae. On day 20, polyps associated with clade D algae show little green fluorescence, and aposymbiotic polyps have a pale fluorescence. Red fluorescence dots indicate the chlorophyll fluorescence of <i>Symbiodinium</i> algae. Polyps with clade C1 algae contain few <i>Symbiodinium</i> cells, although many cells are aggregated around the polyps on days 20 and 58 (Fig. 3), thought to be <i>Symbiodinium</i> algae released from the corals.
