  • Sulfation of fucoidan in Fucus embryos and its possible role in localization

    Creator:
    Crayton, Michele Allen
    Abstract:
    Under defined cultural conditions, zygotes of the brown alga Fucus distichus L. Powell divide synchronously to form two-celled embryos at approximately 24 hours after fertilization. These two cells differ from one another in gross morphology, ultrastructure, cytochemistry, and developmental fate. Cytochemical staining and autoradiography indicated that a sulfated polysaccharide was...

  • Cell wall formation in Fucus zygotes : cellulose synthesis and deposition after fertilization

    Creator:
    Stevens, Patricia T.
    Abstract:
    Under defined cultural conditions, large populations of zygotes of the brown algae Fucus vesiculosus L. and F. distichus L. Powell synchronously form a cell wall shortly after fertilization. Intact cell walls, free of cytoplasm and maintaining shape properties of early stages of embryo development, have been isolated from these zygotes....
