English: Endophytic Verrucomicrobiota: Cell morphology of strains Albicoccus flocculans EW11 (1), Opitutus terrae ER46 (2), Spartobacter rhizophilus LR76 (3), and Astrumicrobium roseum LW23 (4). Columns (A,B): Transmission electron micrographs of thin sections. (C,D) Images of cells stained with SYBR green to reveal condensed nucleic acids inside cells by Confocal Laser Scanning Microscopy. White arrowhead, electron-dense material. Scale bars indicate 500 nm (1–2 A + B, 3–4 B), 1000 nm (3–4 A) or 2 µm (C,D). Endospores were not observed. Specimen preparation through conventional fixation and dehydration lead to an irregular, scattered shape of some cells (2B) as described for other Verrucomicrobiota.
