Symbiotic Associations in the Phenotypically-Diverse Brown Alga Saccharina japonica
The brown alga Saccharina japonica (Areschoug) Lane, Mayes, Druehl et Saunders is a highly polymorphic representative of the family Laminariaceae, inhabiting the northwest Pacific region. We have obtained 16S rRNA sequence data in symbiont microorganisms of the typical form (TYP) of S. japonica and its common morphological varieties, known as "longipes" (LON) and "shallow-water" (SHA), which sh...
متن کاملEvolution and Expansion of the Prokaryote-Like Lipoxygenase Family in the Brown Alga Saccharina japonica
Lipoxygenase (LOX) plays important roles in fatty acid oxidation and lipid mediator biosynthesis. In this study, we give first insights into brown algal LOX evolution. Whole genome searches revealed four, three, and eleven LOXs in Ectocarpus siliculosus, Cladosiphon okamuranus, and Saccharina japonica, respectively. In phylogenetic analyses, LOXs from brown algae form a robust clade with those ...
متن کاملSulfated Galactofucan from the Brown Alga Saccharina latissima—Variability of Yield, Structural Composition and Bioactivity
The fucose-containing sulfated polysaccharides (SP) from brown algae exhibit a wide range of bioactivities and are, therefore, considered promising candidates for health-supporting and medicinal applications. A critical issue is their availability in high, reproducible quality. The aim of the present study was to fractionate and characterize the SP extracted from Saccharina latissima (S.l.-SP) ...
متن کاملLocalization of a Female-Specific Marker on the Chromosomes of the Brown Seaweed Saccharina japonica Using Fluorescence In Situ Hybridization
BACKGROUND There is a heteromorphic alternative life in the brown seaweed, Saccharina japonica (Aresch.) C. E. Lane, C. Mayes et G. W. Saunders ( = Laminaria japonica Aresch.), with macroscopic monoecious sporophytes and microscopic diecious gametophytes. Female gametophytes are genetically different from males. It is very difficult to identify the parent of a sporophyte using only routine cyto...
متن کاملChloroplast and Mitochondrial Dna in a Brown Alga Egregia Menziesii
Chloroplasts and mitochondria of the brown alga Egregia menziesii were studied with the electron microscope. In both organelles, 15-25-A fibrils with DNA characteristics are found within areas of electron transparency. In each chloroplast there are two DNA-containing areas, one at each tip of the chloroplast. This localization, the shape and size of each DNA-containing area, and its close assoc...
