Journal ArticleDOI
The phylogenetic relationship between the Chlamydomonadales and Chlorococcales inferred from 18SrDNA sequence data
TL;DR: The 185rDNA trees clearly demonstrate the non‐monophyly of the Chlamydomonadales and Chlorococcales, suggesting that vegetative morphology does not reflect phylogenetic relationships in the CW group.
Journal ArticleDOI
The Basal Position of Scaly Green Flagellates among the Green Algae (Chlorophyta) is Revealed by Analyses of Nuclear-Encoded SSU rRNA Sequences
Takeshi Nakayama,Birger Marin,Harald D. Kranz,Barbara Surek,Volker A. R. Huss,Isao Inouye,Michael Melkonian +6 more
TL;DR: These analyses provide further evidence for the basal phylogenetic position of the scaly green flagellates among the Chlorophyta and raise important questions concerning the class-level classification of the Ch chlorophyta.
Journal ArticleDOI
Global searches for microalgae and aquatic plants that can eliminate radioactive cesium, iodine and strontium from the radio-polluted aquatic environment: a bioremediation strategy
Shin ya Fukuda,Koji Iwamoto,Mika Atsumi,Akiko Yokoyama,Takeshi Nakayama,Ken-ichiro Ishida,Isao Inouye,Yoshihiro Shiraiwa +7 more
TL;DR: A novel eustigmatophycean unicellular algal strain, nak 9, showed the highest ability to eliminate radioactive Cs from the medium by cellular accumulation, providing an important strategy for decreasing radiopollution in Fukushima area.
Journal ArticleDOI
Vestigial chloroplasts in heterotrophic stramenopiles Pteridomonas danica and Ciliophrys infusionum (Dictyochophyceae).
TL;DR: The results indicated that the loss of photosynthetic ability occurred independently in P. danica and C. infusionum, the first report of the presence of a vestigial chloroplast (leucoplast) in colorless dictyochophytes.
Journal ArticleDOI
Green-colored plastids in the dinoflagellate genus Lepidodinium are of core chlorophyte origin.

TL;DR: It is proposed that Lepidodiniumplastids are of core chlorophyte origin, and 85 sequences newly determined in this study and recent progress in plastid genome sequencing enabled us to prepare an alignment comprised of 11Plastid proteins from green algal taxa that appropriately cover the diversity of Chlorophyta.
