    Application of multigene phylogenetics and site‐stripping to resolve intraordinal relationships in the Rhodymeniales (Rhodophyta)

    Drouetia viridescens Filloramo & G.W. Saunders sp. nov. (a) Habit of single peltate blades attached to substratum by single stipe (not pictured) (GWS032740), scale bar = 1 cm. (b) Habit of tetrasporic holotype showing anastomosed blades that form an irregular outline (GWS032612), scale bar = 1 cm. (c) Transverse section at mid-thallus of vegetative plant (GWS032682), scale bar = 93 μm. (d) Transverse section at mid-thallus of tetrasporic holotype (GWS032612), scale bar = 108 μm. (e) Mature cruciately divided tetrasporangium (GWS032612), scale bar = 33 μm. (f) Transverse section at mid-thallus of tetrasporic holotype showing cortical cell (arrow) compressed between developing and mature tetrasporangia creating the appearance of paraphyses. Tetrasporangial initials pit connected (arrowheads) to inner cortical cell (GWS032612), scale bar = 25 μm. (g) Intercalary tetrasporangial initial pit connected (arrowheads) to two neighboring cortical cells (GWS032612), scale bar = 20 μm.

  • Rhodenigma contortum, an obscure new genus and species of Rhodogorgonales (Rhodophyta) from Western Australia

    Rhodenigma contortum, an obscure new genus and species of Rhodogorgonales (Rhodophyta) from Western Australia

    (A) Unattached filaments with many randomly oriented filaments and some parallel filaments (bar), scale bar is 25 μm. (B) Filaments attached to glass, branching irregularly and forming lateral adhesion to other filaments. Some branch tips making contact with adjacent filaments and possibly fusing (arrowhead), scale bar is 5 μm. (C) Formalin-fixed and aniline-blue-stained specimen. Crust adherent on glass showing veins of single or multiple filaments with narrow elongate cells and lateral complex of shorter more irregular cells and branches, scale bar is 10 μm. Inset shows faintly visible pit connections (arrowheads) between some cells, scale bar is 4 μm.

  • Bacteria may induce the secretion of mucin-like proteins by the diatom Phaeodactylum tricornutum

    Bacteria may induce the secretion of mucin‐like proteins by the diatom Phaeodactylum tricornutum

    Domain organization of selected identified proteins. Characteristic domains identified due to their homology to characterized protein domains were annotated. Proline-, serine-, and threonine-rich regions and cysteine regions are marked as domains. Sketch: signal peptides, gray line; N-terminal peptide backbone, black line; identified domains, sketches as indicated in the inset legend. Numbers represent protein identifiers in the JGI database 2.0 of the Phaeodactylum tricornutum genome annotation and the black bars the total number of identified peptides.

  • A new type of 3-D peripheral ultrastructure in Glaucocystis (Glaucocystales, Glaucophyta) as revealed by ultra-high voltage electron microscopy

    A new type of 3‐D peripheral ultrastructure in Glaucocystis (Glaucocystales, Glaucophyta) as revealed by ultra‐high voltage electron microscopy

    Electron tomography and 3-D modeling of protoplast periphery of “Glaucocystis incrassata” SAG 229-2 vegetative cell. Corresponding to Videos S1 and S2. (a) Ultra-high voltage electron microscopic image, scale bar = 10 μm. Inset shows higher magnification image of the cell periphery (boxed area), inset scale bar = 1 μm. (b) Tomographic image of boxed area in (a). Note that plasma membrane is grooved deeply at varying intervals (arrows), scale bar = 1 μm. M, mitochondrion; P, plastid; V, vacuole; W, cell wall. (c–g) 3-D images showing distribution of plasma membrane (magenta), and underlying flattened vesicles (yellow) associated with microtubules (green) on cytoplasmic side. Not to scale. Arrows indicate that each bar-like groove of plasma membrane is covered by invagination of flattened vesicle. Arrowheads indicate slight overlapping of neighboring flattened vesicles. (c) View with a tomographic image. For abbreviations of organelles, see (b). (d, e) View from cell wall side. (f, g) View from cytoplasmic side.
