The effects of triphenyltin chloride on respiration and photosynthesis in the green algae Enteromorpha intestinalis and Ulothrix pseudoflacca
Plant Cell & Environment, 2006Co-Authors: P. A. Millner, L. V. EvansAbstract:Abstract Respiration and photosynthesis in zoospores of Enteromorpha intestinalis (L.) Link and Ulothrix pseudoflacca Wille showed greater sensitivity to inhibition by triphenyltin chloride than in vegetative tissue. Photosynthesis in zoospores and vegetative tissue of U. pseudoflacca was more resistant to triphenyltin chloride inhibition than in zoospores and vegetative tissue of E. intestinalis. Respiration in zoospores and vegetative tissue of both species was equally sensitive to triphenyltin chloride.

Element Composition and Biogeochemical Functions of Algae Ulothrix Zonata (F. Weber et Mohr) Kützing in the Coastal Zone of the Southern Baikal
Water Resources, 2018Co-Authors: N. N. Kulikova, E. A. Volkova, N. A. Bondarenko, E. P. Chebykin, E. V. Saibatalova, Oleg A. Timoshkin, A. N. SuturinAbstract:ICP-MS method was used to study the element composition of green algae Ulothrix zonata (F. Weber et Mohr) Kutzing, sampled in the coastal zone of the Southern Baikal. Dominating in Ulothrix composition are S, Ca, P, Mg and microelements Fe, Al, Ti, Mn, Sr, Ba, Cu, Zn, La, Ce, As, Br, and Pb. The concentrations of all analyzed elements in alga thallomes is greater than the respective concentrations in coastal zone water. The dry mass of U. zonata accumulates more P, As, S, I, Br, Ni, Cd, Ca, and Mg than the stone substrate does. The effect of U. zonata on the formation of element composition of water medium in the coastal zone is demonstrated.

Temporal variation in fatty acid composition of Ulothrix zonata (Chlorophyta) from ice and benthic communities of Lake Baikal
Phycologia, 2009Co-Authors: Svetlana Osipova, N. A. Bondarenko, Lubov Dudareva, Alexandra Nasarova, Nataliya Sokolova, Lubov A. Obolkina, Olga Glyzina, Oleg A. TimoshkinAbstract:Abstract S. Osipova, L. Dudareva, N. Bondarenko, A. Nasarova, N. Sokolova, L. Obolkina, O. Glyzina and Oleg Timoshkin. 2009. Temporal variation in fatty acid composition of Ulothrix zonata (Chlorophyta) from ice and benthic communities of Lake Baikal. Phycologia 48: 130–135. DOI: 10.2216/08-49 Fatty acid (FA) composition of total lipids was compared between populations of the freshwater alga Ulothrix zonata growing in the interstitial water of the ultrapure ice cover of Lake Baikal in early spring (ice population) and on the shallow stony bottom of the lake during the ice-free season (benthic population). FA content was analysed by chromatographic mass spectrometry. Our observations over two years indicated that the FA profiles of both Baikalian ice and benthic populations of U. zonata, as are typical for other green algae, showed a high level of polyunsaturated FAs (50–70% depending on season) related to the adaptation of the alga to low temperature. Rising temperature in the algal habitat entailed a pro...

An Association between Macromitrium sulcatum (Hook.) Brid. and Ulothrix zonata (Weber & Mohr) Kützing
2012Co-Authors: Afroz Alam, Vinay Sharma, Shiv Charan SharmaAbstract:In succession of terrestrial ecosystem, bryophytes, algae and lichens constitute the primary components. Not only phylogenetically but also physically they are related to each other, as they are also found in close association and intermixed with each other on same substratum. A chlorophycean alga Ulothrix zonata (Weber & Mohr) Kutzing has been found growing as an epiphyte on moss Macromitrium sulcatum (Hook.) Brid.. The association is peculiar as the algal filaments form a close net over the surface of moss leaves and axis.
