posted on 2014-06-10, 03:07 authored by Ikuko Yuyama, Tomihiko HiguchiBright 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 Symbiodinium algae. Polyps with clade C1 algae contain few Symbiodinium cells, although many cells are aggregated around the polyps on days 20 and 58 (Fig. 3), thought to be Symbiodinium algae released from the corals.
