Brown Algae
Brown algae, the Phaeophyceae (or Fucophyceae; Christensen, 1978), are a class (or division, Phaeophyta; Papenfuss, 1951) of algae consisting mainly of complex, macroscopic seaweeds whose brown color comes from a carotenoid pigment, fucoxanthin, and in some species, various phaeophycean tannins. Of perhaps 2000 species (in 265 genera) of brown algae (Van den Hoek et al., 1995), less than 1% are...
متن کاملBrown algae
(also known as array genomic comparative hybridization, or array CGH) with established diagnostic procedures including G-banded karyotype and fragile X testing. Arrays for CMA tests are widely available, but have not yet entered general practice to the extent that generally agreed standards and references exist. Applying CMA to the entire genomes of 697 ASD patients, Shen et al. detected clinic...
متن کاملPhotochemoprevention of UVB-induced skin carcinogenesis in SKH-1 mice by brown algae polyphenols.
Chronic exposure of the skin to ultraviolet B (UVB) radiation induces oxidative stress, which plays a crucial role in the induction of skin cancer. In this study, the effect of dietary feeding and topical application of brown algae polyphenols on UVB radiation-induced skin carcinogenesis in SKH-1 mice was investigated. SKH-1 hairless mice were randomly divided into 9 groups, including control, ...
متن کاملDistribution of pyrenoids among some brown algae.
The distribution of pyrenoids among some orders of the brown algae has been investigated with the electron microscope and a report on their occurrence is given, with particular reference to the results obtained with the light microscope by Simon (1954). Some illustrated detail of the structure of the pyrenoids and of the chromatophores is included. Pyrenoids were found to be present in the repr...
متن کاملSexual recognition and fertilization in brown algae.
Fertilization in the brown marine algae known as fucoids, is oogamous. The naked egg cell (80 micron diam.) is fertilized by small biflagellate spermatozoids and both monoecious and dioecious species are found. Fertilization is highly species-specific and this appears to be controlled during plasmogamy. Following fusion of egg and sperm, a rapid (less than 1 min) release of polyuronide cell wal...
