Validation of the name Asterosiphon dichotomus (Xanthophyceae)

Phytotaxa, 2019
Asterosiphon Dangeard (1940: 720) presents a monospecific genus of xanthophytes, which can be easily distinguished from other genera in having filamentous siphons and exclusively asexual reproduction. Asterosiphon species forms macroscopic rosette of a few millimeters in diameter consisting of green procumbent and dichotomously branched siphons which ...

Zum Feinbau von Botrydium granulatum Grev. (Xanthophyceae)

Archiv f�r Mikrobiologie, 1967
Die polyenergide Xanthophycee Botrydium granulatum wurde nach Glutaraldehydfixierung elektronenmikroskopisch an Ultradunnschnitten untersucht. 1. Die Energiden sind cytomorphologisch nicht gegeneinander abgegrenzt. 2. Die Chromatophoren besitzen keine Grana, ihre Thylakoide sind zu Dreiergruppen assoziiert.

Antheraxanthin-Zeaxanthin-Umwandlung in Vaucheria sessilis (Xanthophyceae)

Planta, 1967
There is a light-induced transformation of antheraxanthin to zeaxanthin in the heterokont alga Vaucheria. This reaction can be reversed in the dark. The other carotenoids remain unchanged under the influence of light.

Osmotic adjustments in a psychrophilic alga, Xanthonema sp. (Xanthophyceae)

Environmental and Experimental Botany, 2008
Abstract Extremophile microalgae show a remarkable ability to cope with harsh environments, yet still relatively little is known about the molecular basis for such tolerance. In this work the susceptibility of a psychrophylic alga isolated from alpine snowbanks, Xanthonema sp., to either water or salt stress conditions was assessed, and mechanisms ...

???????? ?????????? Botrydium Wallroth ?? Vaucheria De Candolle (Xanthophyceae) ?????? ?????????????????????? (????????????)

2019
The yellow green algae belonging to the genera Botrydium and Vaucheria (Xanthophyceae) were studied in the south of the Baikal region from 2011 to 2017. As a result, 375 populations of 15 siphonous xanthophytes from Botrydium (1 species) and Vaucheria (13 species and 1 variety) have been revealed in the 218 localities of the studied region.

Kultur und Entwicklung von Chlorocloster engadinensis Vischer (Xanthophyceae)

Archiv f�r Mikrobiologie, 1965
Die autotrophe, mixotrophe und heterotrophe Kultur der einzelligen Xanthophycee Chlorocloster engadinensis Vischer wird beschrieben. Diese Alge kann unter allen drei Bedingungen mit vergleichbaren Wachstumsraten kultiviert werden. Sie stellt neben den bekannten Chlorophyceen Chlorella, Scenedesmus und Ankistrodesmus ein weiteres gunstiges Objekt fur ...

Structural organization and evolution of the plastid genome of Vaucheria sessilis (Xanthophyceae)

Biosystems, 1988
The plastid DNAs of 18 Vaucheria sessilis strains from various habitats in western Europe were digested with the restriction endonucleases Eco RI, Sal I, Bam HI and Pvu II. Their restriction patterns showed variable fragment divergencies. Two main groups of plastid genomes were recognized, which were substantiated by morphological features.

Gallen in Vaucheria-draden (Algen-Xanthophyceae)

1972
Vaucheria racemosa (Vauch.) DC. with galls caused by the rotifer Proales wernecki (Ehrenb.) was found in a small ditch in the polder “het Oude land van Strijen” in the “Hoekse Waard” (prov. Z.-Holland), in the autumn of 1970. A survey of the literature is given.

[Antheraxanthin-zeaxanthin conversion in Vaucheria sessilis (Xanthophyceae)].

Planta, 2014
There is a light-induced transformation of antheraxanthin to zeaxanthin in the heterokont alga Vaucheria. This reaction can be reversed in the dark. The other carotenoids remain unchanged under the influence of light.
