Heterokonts (Xanthophyceae and Chrysophyceae) in Rivers

open access: yes, 2016
The heterokont classes Xanthophyceae and Chrysophyceae are introduced with its key characteristics and typical benthic river genera. Two relatively widespread genera are the xanthophyte siphonous Vaucheria and the filamentous Tribonema. The heterokont classs (Chrysophyceae) genus Hydrurus is also listed, which consists of a branched colony and can be ...

Phylogeny and Taxonomy of Xanthophyceae (Stramenopiles, Chromalveolata)

Protist, 2009
The stramenopile class Xanthophyceae has been variously divided into two to seven orders. Previous molecular phylogenetic analyses of the class have had limited taxon/gene sampling or have focused on particular taxa. Despite these limitations para-polyphyletic groups have been identified at different taxonomic ranks. To investigate the phylogeny of the

Xanthophyceae, Euglenophyceae and Dinophyceae

Cellular Origin and Life in Extreme Habitats, 2015
Xanthophyceae, Euglenophyceae and Dinophyceae are among those important algal groups which are less diverse than other major groups of algae. Members of Xanthophyceae and Euglenophyceae do not contaminate water, whereas Dinoflagellates causes various types of poisoning. Many important algal members have been included and excluded in these groups due to

MOLECULAR SYSTEMATICS OF THE XANTHOPHYCEAE

Journal of Phycology, 2000
Species belonging to the Xanthophyceae have traditionally been classified in six (or seven) orders corresponding to amoeboid, coccoid, filamentous, monadoid, palmelloid and siphonous lines of descent. We have determined plastid rbcL and nuclear 18S rRNA gene sequences for selected coccoid, filamentous and siphonous species.

Xanthophyceae

2016
The Xanthophyceae is a clade of stramenopilan photoautotrophs containing about 118 genera and 600 species. Morphology ranges from free-living or attached unicells to colonies and unbranched or branched filaments and siphons. A large majority are found in freshwater and soil, while some occur in brackish and marine habitats.

The flagellar apparatus in Tribonema (Xanthophyceae) reinvestigated

Phycologia, 2003
Abstract In order to fill gaps in the knowledge of the zoospore ultrastructure of the genus Tribonema (Xanthophyceae, Heterokontophyta), the absolute three-dimensional structure of its flagellar apparatus has been reconstructed using transmission and scanning electron microscopy.
