a, c, e Slices through reconstructed 3D volumes; some features in the highlighted rectangles are artificially colored according to the color code in b (pSDV membrane - proximal SDV membrane, dSDV membrane - distal SDV membrane). b, d Three-dimensional surface rendering of segmented volumes. f Schematic showing the proposed valve exocytosis mechanism of diatoms. a and c show different locations on the same daughter cells, indicated in f. Scale bars: 100 nm, slice thickness 1.15–5.7 nm. See also Movies S2, 3.
