Fig. 1: Host cell types and symbionts of Acropora aspera.

a Sorted cell suspension of symbiotic coccoid-shaped dinoflagellates from A. aspera (bright field, pink colored autofluorescence in Gy5 channel marks chlorophyll). b Nematocysts in host cell suspension. c, d b-Mastigophores. e p-Mastigophore. f, g Holotrichous isorhizas. h Spirocyst. i, j Transmission electron micrographs of cross sections through nematocyte. k Small agranular host cells. l Agranular and granular host cells. m–r Granular host cells. s Transmission electron micrographs of cross section through A. aspera tentacle. The letter designations are as follows: ac agranular cell, g granule, gc granular cell, n nucleus, nc nematocyst, nw nematocyst’s wall, pm plasma membrane, s spines, sh shaft, t tubule, v V-shaped notch at the end of shaft, Ep epidermis, Ga gastrodermis, Me mesoglea, m mucous cell, nc nematocyst, and d symbiotic dinoflagellates. Blue fluorescence indicates nuclear DNA stained with DAPI.
