Disease relevance of Algae, Brown

  • The tests on brown algae found that as compared with ammonium, the toxicity to nitrate-grown cultures is higher by a factor of about 10 [1].
  • As a part of a screening program for natural products from microorganisms, 465 actinomycetes strains and 278 fungal strains were isolated from 44 seaweed specimens (Rhodophyta and Phaeophyta), collected in the Iberian peninsula seashore (Atlantic and Mediterranean coasts) [2].
 

High impact information on Algae, Brown

  • A p34 protein is detectable in oats and Arabidopsis and in remote taxa, including red and brown algae [3].
  • Higher plants produce the C11 hydrocarbons from dodeca-3,6,9-trienoic acid; brown algae exploit the family of icosanoids for biosynthesis of the same compounds [4].
  • Thus, the branched fucans from brown algae are direct inhibitors of thrombin, whereas the linear fucans from echinoderms require the presence of antithrombin or heparin cofactor II for inhibition of thrombin, as reported for mammalian glycosaminoglycans [5].
  • Dictyoxepin and dictyolene, two new diterpenes from the marine alga Dictyota acutiloba (Phaeophyta) [6].
  • These studies of the brown algae Fucus distichus examined whether auxin and auxin transport are also required during polarization in early embryos and to orient growth in already developed tissues [7].

Gene context of Algae, Brown

  • In this paper, we investigated interactions of the acidic oligosaccharide sugar chain (AOSC), derived from brown algae Echlonia kurome OKAM, with amyloid beta protein (Abeta) [20].
  • In general, the red algae metabolize C20 acids via 12-lipoxygenase-initiated pathways, green algae metabolize C18 acids at C-9 and C-13, and brown algae metabolize both C18 and C20 acids, principally by lipoxygenases with n-6 specificity [21].
