Summary of "Morphology and molecular phylogeny of coccoid green algae Coelastrella sensu lato (Scenedesmaceae,Sphaeropeales), including the description of three new species and two new varieties."

The genus Coelastrella was established in 1922 by Chodat, and was characterized by being unicellular or in few-celled aggregations with many longitudinal ribs on cell wall. Many species of this genus showed strong ability to accumulate carotenoids and oils, so they have recently attracted many attentions from researchers due to its potential applicability in the energy and food industries. In this study, a total of 23 strains of Coelastrella were sampled from China, and 3 new species, 2 new varieties were described: C. thermophila sp. nov., C. yingshanensis sp. nov., C. tenuitheca sp. nov., C. thermophila var. globulina var. nov., C. rubescens var. oocystiformis var. nov. Besides 18S rDNA and ITS2 sequences, we have newly sequenced the tufA gene marker for this taxon. Phylogenetic analysis combined with morphological studies revealed 4 morphotypes within the Coelastrella sensu lato clade, which contained the morphotype of original Coelastrella, original Scotiellopsis, Asterarcys, and morphotype of C. vacuolata and C. tenuitheca sp. nov.. The relationships between morphological differences and phylogenic diversity based on different markers were discussed. Our results support that 18S rDNA was too conserved to be used a species-specific or even a genus-specific marker in this clade. The topology of tufA gene-based phylogenetic tree had a better match with the morphological findings.

Medical and Biotech [MESH] Definitions

Algae of the division Chlorophyta, in which the green pigment of CHLOROPHYLL is not masked by other pigments. Green algae have over 7000 species and live in a variety of primarily aquatic habitats. Only about ten percent are marine species, most live in freshwater. They are more closely related to the green vascular land PLANTS than any other group of algae.

Algae of the division Rhodophyta, in which the red pigment (PHYCOERYTHRIN) predominates. However if this pigment is destroyed, the algae can appear purple, brown, green, or yellow. Two important substances found in the cell walls of red algae are AGAR and CARRAGEENAN. Red algae are thought to be closely related to the prokaryotic CYANOBACTERIA.

A phylum of oxygenic photosynthetic bacteria comprised of unicellular to multicellular bacteria possessing CHLOROPHYLL a and carrying out oxygenic PHOTOSYNTHESIS. Cyanobacteria are the only known organisms capable of fixing both CARBON DIOXIDE (in the presence of light) and NITROGEN. Cell morphology can include nitrogen-fixing heterocysts and/or resting cells called akinetes. Formerly called blue-green algae, cyanobacteria were traditionally treated as ALGAE.

A phylum of green plants comprising CHAROPHYCEAE (streptophyte green algae) and EMBRYOPHYTA (land plants).

A monophyletic group of green plants that includes all land plants (EMBRYOPHYTA) and all green algae (CHLOROPHYTA and STREPTOPHYTA).
