Extended Data Figure 8 : Continuity between the retinal body and the plastid network in Nematodinium sp.

From: Eye-like ocelloids are built from different endosymbiotically acquired components

Extended Data Figure 8

a, FIB-SEM slice of plastids attached to retinal body. b, TEM overview of ocelloid in a high-pressure frozen cell. c, FIB-SEM overview of ocelloid in a high-pressure frozen cell. d, Three-dimensional reconstruction of the ocelloid shown halved. e, Three-dimensional reconstruction of the ocelloid in full. f, Fusion site between plastids joined to the retinal body as seen in TEM. g, Site where the waveform-membrane region of the ocelloid joins to a region with thylakoids as seen in TEM. Inset shows thylakoids, and corresponds to the box in the main image. h, Fusion site as seen through FIB-SEM. i, Tracing of membrane continuity in Amira. j, Partial reconstruction of the ocelloid in Amira. Arrowheads point to fusion zones between sites bounded by the plastid membrane (reconstructed in red), blue denotes mitochondria, yellow denotes the surface of the lens. L, lens; w, waveform membranes; t, thylakoids.
