Synaptonemal Complexes in Brown Algae

Nature, 1973
THE 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.

Sterol compositions in some green algae and brown algae

Steroids, 1968
Abstract 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.

Viruses in Marine Brown Algae

1998
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 (Fucoxanthin) Against Cancer

2021
Fucoxanthin is recognized well all over the world due to its beneficial health effects. It is widely available in nature as a carotenoid and accounts for more than 10% of total carotenoids production in the world. Since, it disguises the green chlorophyll a and c therefore; it gives yellow to brown color to diatoms and seaweed (Brown macroalgae).

Viruses Infecting Marine Brown Algae

Virus Genes, 1998
Viruses infecting algal hosts possess large double-stranded DNA as genomes. We have recently identified a family of viruses specific for filamentous brown algae. In contrast to the better known Chlorella viruses with their lytic infection cycle, marine brown algal viruses latently occur in their host cells and are induced to multiply in response to a ...

Sexual dimorphism in the brown algae

Perspectives in Phycology, 2014
Sexual 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 ...

Sulphated polysaccharide synthesis in brown algae

Planta, 1973
Histochemical and autoradiographic techniques have been used to investigate the sites of synthesis, transport and location of sulphated polysaccharides in some larger brown seaweeds.The most rapid uptake of (35)SO4 occurred when material was incubated in medium with 10(-4)M carrier sulphate, negligable uptake occurring from seawater.Autoradiography ...
