    Cell-cell adhesion in conjugatingChlamydomonas gametes: a self-enhancing process (1988)
    Springer
    Protoplasma 145 (1988), S. 27-36 
    Details
    ISSN: 1615-6102
    Schlagwort(e): Adhesion ; Agglutinin ; Chlamydomonas ; Flagellum

    Thema: Biologie
    Notizen: Summary The flagellar adhesiveness of gametes ofChlamydomonas eugametos increases during conjugation such that the cell-cell contacts are intensified. The rise in adhesiveness is due to an increase in agglutinin exposure which can be visualized by immunolabeling. The adhesiveness in the one cell is stimulated by the agglutinins of the adherent partner cell, and vice versa. Thus, sexual cell-cell adhesion is a self-enhancing process. In addition, it is shown that the gametes are able to activate potential partners at distance via agglutinin-rich vesicles which they shed into their environment.

    Cell-cell coordination in conjugatingChlamydomonas gametes (1990)
    Springer
    Protoplasma 155 (1990), S. 188-199 
    Details
    ISSN: 1615-6102
    Schlagwort(e): Adhesion ; Agglutinin ; Chlamydomonas ; Conjugation ; Flagellum ; Gamete ; Signalling
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Biologie
    Notizen: Summary During conjugation, complementaryChlamydomonas gametes [mating type plus (mt+) and mating type minus (mt−)] are mutually attached via specific adhesion molecules, called agglutinins, which are located at the surface of the flagella. By these contacts the gametes are stimulated to fuse. It is demonstrated that fusion is preceded by a compulsary sequence of events: first, the flagellar swimming beat is arrested, next the flagellar contact is reinforced and finally, the position of the cell bodies is adjusted to permit fusion. Evidence is presented that each consecutive step of the mating process requires a higher level in cell-cell signalling, which is obtained by the formation of additional agglutinin contacts. It is shown that the mt+ and mt− traverse their conjugation process in synchrony, probably because the two sexes acquire new agglutinin contacts at equal rates. It is proposed that this symmetrical behavior is due to the complementarity of the mt+ and mt− agglutinin molecules. A scenario of the conjugation process inC. eugametos, incorporating the recent findings, is provided.

    Beschreibung / Inhaltsverzeichnis: Drei Entwürfe für Doppelsektor-Zellen werden vorgeschlagen. Die Entwürfe machen es möglich, Dichtegradienten-Versuche mit in beiden Sektoren gleichen Säulenhöhen auszuführen. Sie garantieren auch, daß die Säulenhöhen von Versuch zu Versuch identisch sind.
    Notizen: Three different designs for double sector cells are presented. The designs allow density gradient experiments to be carried out with equal column lengths in each sector. Also they assure equal heights of the columns from experiment to experiment.

    Notizen: Four styrene-iodostyrene copolymers of uniform iodine content are examined in the density gradient centrifuge under conditions similar to those used in a previous study, in which the copolymer investigated showed compositional distribution. The results obtained determine the relation between the iodine content of a copolymer and its position in the density gradient. This enables one to compare the average square of the fluctuation in iodine content with that derived from the kinetic copolymer equation. The two results agree satisfactorily.

    Notizen: A well-defined graft copolymer of polystyrene and cellulose acetate has been investigated using the density gradient ultracentrifugation method. The initial sample showed two peaks. These were found to be pure graft copolymer and polystyrene; the latter was easily removed by further extraction of the mixture with benzene. The composition of the graft copolymer was determined from the buoyant densities of the graft and the two homopolymers and found to be 49% polystyrene, 51% cellulose acetate compared with 44.1 and 55.9%, respectively, estimated from the weight loss after acid hydrolysis.
