Two Minor Diterpenes Related to Dictyodial a From the Brown Alga Dictyota crenulata
Phytochemistry, 1983 4β-Hydroxydictyodial A and 18,O-dihydro-4β-hydroxydictyodial A 18-acetate are two minor aldehydic diterpenes in the brown alga Dictyota crenulata. 1H NMR and lanthanide-induced chemical shift studies indicate that the relative stereochemistry of both ...

Synaptonemal Complexes in Brown Algae
Nature, 1973THE small size of the nuclei of many brown algae makes it difficult to observe the chromosomes and their configurations in nuclear divisions, although life history studies and investigations of nuclei with the light microscope suggest that meiosis in these forms takes place in the unilocular sporangia.

Sexual dimorphism in the brown algae
Perspectives in Phycology, 2014Sexual dimorphisms have been described in several groups of organisms, but while an important number of investigations have focused on animal and plant systems, much less is known about this phenomena in other eukaryotes. We review here the current know ledge on sexual dimorphisms in the brown algae, a group of multicellular eukaryotes that have been ...

Sterol compositions in some green algae and brown algae
Steroids, 1968Abstract Compositions of the sterol in Chlorophyta and Phaeophyta were established quantitatively. Sterol content in Chlorophyta is more similar to higher plant, and it contains large amount of cholesterol. In Phaeophyta, fucosterol is the main sterol and small amounts of cholesterol, 24-methylene-cholesterol and saringosterol were identified.

Publisher Summary Virus-like particles have been repeatedly reported from multicellular marine red and brown algae, and the release of viruses from infected algal hosts into the surrounding sea water also contributes to the number of virus-like particles in coastal waters. It has become apparent that they are intimately and unseparably connected with

Brown Algae as a Model for Plant Organogenesis
2012Brown algae are an extremely interesting, but surprisingly poorly explored, group of organisms. They are one of only five eukaryotic lineages to have independently evolved complex multicellularity, which they express through a wide variety of morphologies ranging from uniseriate branched filaments to complex parenchymatous thalli with multiple cell ...

Cytoplasmic inheritance of organelles in brown algae
Journal of Plant Research, 2010Brown algae, together with diatoms and chrysophytes, are a member of the heterokonts. They have either a characteristic life cycle of diplohaplontic alternation of gametophytic and sporophytic generations that are isomorphic or heteromorphic, or a diplontic life cycle.

Strontium, Calcium and Magnesium in Brown Algae
Nature, 1967THE ion exchange properties of alginates have received some attention lately, particularly because of their potential value in connexion with therapy after strontium-90 overdoses1–3. It has been shown that alginates rich in guluronic acid residues have a greater affinity for calcium in the ion exchange reaction calcium–magnesium4 and for strontium in ...

Economic Botany, 1954
The enormous and self-replenishing supplies—perhaps 200 or 300 million tons—of these seaweeds in the oceans of the world have been commercially exploited so far primarily in the production of alginic acid, but the other carbohydrates, proteins, lipids, vitamins, enzymes and antibacterial substances in them and discussed here may hold even greater ...
