Fig. 3: Representative transmission electron microscopy (TEM) images of Symbiodiniaceae from colonies of the Pacific stony coral, Acropora hyacinthus, in an aquaria-based experiment.
From: Filamentous virus-like particles are present in coral dinoflagellates across genera and ocean basins
A Apparently healthy cell; B degraded cell with no significant visible filamentous virus-like particles (VLPs); C representative Symbiodiniaceae cell reproduced from [22] containing filamentous VLPs from a stony coral tissue loss disease (SCTLD)-affected coral colony. D–F Symbiodiniaceae cell containing filamentous VLPs similar to those in [22], sampled from an apparently healthy A. hyacinthus colony. E is an inset of (D); F is an inset of (E). G–I Symbiodiniaceae cell containing filamentous VLPs similar to those in [22], sampled from a heat stressed A. hyacinthus colony. (H) is an inset of (G); I is an inset of (H). Arrows point to the sagittal length of a VLP; arrowheads point to the cross section of a VLP. P – pyrenoid body; n – nucleus; c – chloroplast.
