  • The ghost plastid of Choreocolax polysiphoniae

    The ghost plastid of Choreocolax polysiphoniae

    Mauve alignment of Choreocolax polysiphoniae (top) and Vertebrata lanosa (second from top) and other published Florideophyceae plastid genomes. This alignment identifies 13 locally collinear blocks (LCBs) among all Florideophycean plastid genomes while highlighting the reduction and fragmentation evident in C. polysiphoniae.

  • Compartmentation of defensive compound synthesis in a red alga

          Compartmentation of defensive compound synthesis in a red alga

    Scanning electron microscopy figure of a fractured cortical cell of Plocamium brasiliense (Rhodophyta) where the organelle containing the mevalonate pathway, the mevalonosome can be seen. Red – the mevalonosome; green – chloroplasts; blue – vesicles budding/budded from the mevalonosome; yellow – cell membrane; violet – cell wall; bar = 10 μm.

  • Phylogenetic analysis of cultivation-resistant terrestrial cyanobacteria with massive sheaths (Stigonema spp. and Petalonema alatum, Nostocales, Cyanobacteria) using single-cell and filament sequencing of environmental samples

    Phylogenetic analysis of cultivation‐resistant terrestrial cyanobacteria with massive sheaths (Stigonema spp. and Petalonema alatum, Nostocales, Cyanobacteria) using single‐cell and filament sequencing of environmental samples

    Morphology of Stigonema in environmental samples used for single-cell isolation and sequencing. (a, b) Stigonema tomentosum CAT1C; (c) Stigonema hormoides CAT3A; (d, e) Stigonema panniforme CZ; (f, g) Stigonema panniforme Hawaii; (h, i) Stigonema robustum CR, (j, k) Stigonema turfaceum CAT5C; scale bars: 20 μm.

  • Oospore dimensions and morphology in North American Tolypella (Charophyceae, Charophyta)

    Oospore dimensions and morphology in North American Tolypella (Charophyceae, Charophyta)

    SEM images of oospores from species in Tolypella section Tolypella. (A) T. glomerata—general aspect. (B) T. glomerata—parallel-like rows of reticulation on fossa wall. (C) T. glomerata—single basal segment. (D) T. glomerata—general aspect. (E) T. glomerata—parallel-like rows of reticulation on fossa wall. (F) T. glomerata—single basal segment. (G) T. glomerata (syn. T. glomerata v. abbreviata)—general aspect. (H) T. glomerata (syn. T. glomerata v. abbreviata)—parallel-like rows of reticulation on fossa wall. (I) T. glomerata (syn. T. glomerata v. abbreviata)—single basal segment. (J) T. glomerata (syn. T. longicoma)—general aspect. (K) T. glomerata (syn. T. longicoma)—appearance of some reticulation on fossa wall. (L) T. porteri—general aspect showing smooth to finely granulate fossa walls. Scale bars: A, C, D, F, G, I, J, L = 10 μm; B, E, H, K = 1 μm.

  • Biofilm and capsule formation of the diatom Achnanthidium minutissimum are affected by a bacterium

    Biofilm and capsule formation of the diatom Achnanthidium minutissimum are affected by a bacterium

    Xenic (A, C, E) and axenic (B, D, F) cultures of the diatom Achnanthidium minutissimum. The xenic cultures formed macroscopic visible aggregates when cultivated on a shaker (A), while the axenic cells grew suspended (B). Alcian blue stained cells with diffuse EPS in the xenic (C) and axenic (D) cultures and early capsule formation in the xenic culture in the early stationary phase. In the late stationary phase, capsules of the xenic culture are fully developed (E), but missing in the axenic culture (F). Autofluorescence of the chl appears as bright red area in the cells. Scale bars denote 10 μm.
