Molecular phylogenetic study of the heterotrophic dinoflagellate genus Protoperidinium (Dinophyceae) inferred from small subunit rRNA gene sequences
TLDR
Most of the traditionally defined sections of the genus Protoperidinium are supported by molecular phylogeny, and it was indicated that the section Avellana evolved from one of the Conica‐type dinoflagellates. Expand
Morphology, phylogeny and novel chemical compounds from Coolia malayensis (Dinophyceae) from Okinawa, Japan
TLDR
The five compounds in the C. malayensis from Okinawa are composed of less oxygen, compared to cooliatoxin and other analogs of yessotoxin, suggesting the metabolites produced by C.malayensis are unique to those previously reported from other strains of Coolia. Expand
Morphostasis in a novel eukaryote illuminates the evolutionary transition from phagotrophy to phototrophy: description of Rapaza viridis n. gen. et sp. (Euglenozoa, Euglenida)
TLDR
The marine mixotrophic mode of nutrition, the preference for green algal prey cells, the structure of the feeding apparatus, and the organization of the pellicle are outstanding examples of morphostasis that clarify pivotal stages in the evolutionary history of this diverse group of microbial eukaryotes. Expand
Molecular phylogeny of the marine sand-dwelling dinoflagellate Herdmania litoralis and an emended description of the closely related planktonic genus Archaeperidinium Jörgensen
TLDR
A novel, well-supported clade comprising both sand-dwelling species (H. litoralis and Thecadinium dragescoi) and planktonic species (P. minutum) is established and the genus Archaeperidinium Jörgensen 1912 is reinstated and emended. Expand
A further phylogenetic study of the heterotrophic dinoflagellate genus, Protoperidinium (Dinophyceae) based on small and large subunit ribosomal RNA gene sequences
TLDR
Analysis of the LSU r DNA data resulted in the same phylogeny as that obtained using SSU rDNA data and, with increased taxon sampling, including members of new sections, a clearer idea of the evolution of morphological features within the genus Protoperidinium was obtained. Expand
Testudodinium gen. nov. (Dinophyceae), a new genus of sand‐dwelling dinoflagellates formerly classified in the genus Amphidinium
TLDR
Phylogenetic trees based on small subunit (SSU) rDNA revealed that all three of these Testudodinium species formed a robust clade and, although statistical support is not high, the tree suggests Testuddinium clade is not closely related to Amphidinium seusu stricto clade. Expand
Mn(II) oxidation in Pseudomonas putida GB-1 is influenced by flagella synthesis and surface substrate
TLDR
Results suggest that bacterial Mn(II) oxidation is regulated in part by flagellar-mediated responses to the surface substrate. Expand
Relationship between the dinoflagellate cyst Spiniferites pachydermus and Gonyaulax ellegaardiae sp. nov. from Izmir Bay, Turkey, and molecular characterization
TLDR
The phylogenetic relationship of G. ellegaardiae is elucidated through large and small subunit ribosomal DNA and it is shown that it forms a clade with other species that belong to the G. spinifera complex. Expand
Molecular Phylogeny and Morphology of Haplozoon ezoense n. sp. (Dinophyceae): A Parasitic Dinoflagellate with Ultrastructural Evidence of Remnant Non-photosynthetic Plastids.
This study describes a novel species of Haplozoon, H. ezoense n. sp., a dinoflagellate parasite isolated from the intestines of Praxillella pacifica (Polychaeta). Trophonts (feeding stages) of H.Expand
Effects of causeway construction on environment and biota of subtropical tidal flats in Okinawa, Japan.
TLDR
Results indicate reduction in water flow, and site S1 was particularly heavily impacted by poor water quality, with low diversity and disturbed biotic communities. Expand
