High impact information on Ulva

• The procedure was validated by analyzing cadmium in three certified reference materials, that is, river sediment (CRM 320), sea lettuce (CRM 279), and frozen cattle blood (GBW 09140) [1].
• Previous studies of Ulva zoospore attachment to a series of mixed methyl- and hydroxyl-terminated SAMs showed a similar correlation between substratum theta(AW) and zoospore attachment [2].
• Photon- and carbon-use efficiency in Ulva rigida at different CO2 and N levels [3].
• Solar ultraviolet radiation affects the activity of ribulose-1,5-bisphosphate carboxylase-oxygenase and the composition of photosynthetic and xanthophyll cycle pigments in the intertidal green alga Ulva lactuca L [4].
• These findings complement an earlier study which indicated that a plasmalemma-bound, disulfonic stilbene-sensitive, protein was functionally involved in HCO3- transport into the photosynthesizing cells of Ulva (Z. Drechsler et al. 1993, Planta 191, 34-40) [5].

Biological context of Ulva

• The effect of solar ultraviolet radiation on photosynthetic activity, the composition of photosynthetic and xanthophyll cycle pigments, and the amount of RubisCO, chaperonin 60 (CPN 60), and the induction of DNA damage in Ulva aff. rotundata Bliding from southern Spain was assessed in the field [6].
• A link between lead and cadmium kinetic speciation in seawater and accumulation by the green alga Ulva lactuca [7].
• Kinetics of inactivation of Ulva pertusa Kjellm alkaline phosphatase by ethylenediaminetetraacetic acid disodium [8].
• The temporal variation of Polonium-210 (210Po) was examined in coastal sea water, the mussel Mytilus edulis, the winkle Littorina littorea and green alga Ulva lactuca in order to investigate the entry of 210Po into the marine food chain [9].
• The mercury biosorption onto non-living protonated biomass of Ulva lactuca, as an alternative method for mercury removal from aqueous solutions, was investigated [10].

Anatomical context of Ulva

• Polypeptides present in a membrane fraction of the marine macroalga Ulva sp. were separated by sodium dodecyl sulfate-polyacrylamide gel electrophoresis and tested for cross-reactivity with antibodies raised against the human red-blood-cell anion exchanger (AE1) [5].

Associations of Ulva with chemical compounds

• H blood group detection by the L-fucose binding lectin of the green marine alga Ulva lactuca [11].
• Of the heterogeneous cross-linked network coatings, the maximum resistances to protein, lipopolysaccharide, and Ulva zoospore adhesion, as well as the best zoospore and sporeling release properties, were recorded for the HBFP-PEG45 coating [12].
• A physico-chemical study on the polysaccharide ulvan from hot water extraction of the macroalga Ulva [13].
• Metal accumulation in the green macroalga Ulva fasciata: effects of nitrate, ammonium and phosphate [14].
• Nevertheless, 40% of the sulphate in Ulva was dissimilated to sulphide by sulphate-reducing bacteria [15].

Gene context of Ulva

• The regulation of the antioxidant defence system by ultraviolet-B (UV-B) was determined in a marine macroalga Ulva fasciata Delile exposed to low (0.5, 1 W m(-2)), medium (2.5, 5 W m(-2)), and high (10, 20 W m(-2)) UV-B irradiance [16].
• Molecular-replacement calculations using the structure of plastocyanin from Ulva pertusa have been performed [17].
• Method accuracy was checked with a certified reference material (sea lettuce, Ulva lactuca, BCR CRM 279) for external calibration and by spiking arsenic standard into different TCMs [18].
• Ulva latuca was selected from the "Marine Park" in Tokyo Bay, and its growth rate (g-dry/[m2.d]) was measured using model reactors located on the land or on the surface of the sea at Yokohama [19].
