Alternative Cold Response Modes in Chlorella (Chlorophyta, Trebouxiophyceae) from Antarctica
Phycologia, 2008Chlorella was known to show enhanced antifreeze capability after cold hardening. We isolated Chlorella strains NJ-7 and NJ-18, which display alternative cold response modes from rock surfaces in Antarctica. On the basis of 18S ribosomal (rRNA) sequences, NJ-7 is an Antarctic type of Chlorella vulgaris; NJ-18 is also a 'true' Chlorella species but ...

Meiotic genes and sexual reproduction in the green algal class Trebouxiophyceae (Chlorophyta)
Journal of Phycology, 2015Sexual reproduction is widespread in eukaryotes and is well documented in chlorophytan green algae. In this lineage, however, the Trebouxiophyceae represent a striking exception: in contrast to its relatives Chlorophyceae and Ulvophyceae this group appears to be mostly asexual, as fertilization has been rarely observed.

Non-flagellated vegetative green algae of the Trebouxiophyceae propagate mainly by autosporulation. In this manner, the mother cell wall is shed following division of the protoplast in each round of cell division. Binary fission type Nannochloris and budding type Marvania are also included in the Trebouxiophyceae.

CILIATE‐SYMBIONT SPECIFICITY OF FRESHWATER ENDOSYMBIOTICCHLORELLA(TREBOUXIOPHYCEAE, CHLOROPHYTA)1
Journal of Phycology, 2008The nature ofChlorellasymbioses in invertebrates and protists has attracted much interest, but the uncertain taxonomy of the algal partner has constrained a deeper ecological understanding of this symbiosis. We sequenced parts of the nuclear 18S rDNA, the internal transcribed spacer (ITS)‐1 region, and the chloroplast 16S rDNA of ...

Polyphyletic origin of the Dictyosphaerium-morphotype within Chlorellaceae (Trebouxiophyceae).
2010The green algal Dictyosphaerium morphotype is characterized by spherical or oval cells connected by gelatinized strands to microscopic colonies, which are covered by prominent mucilaginous envelopes. Combined SSU and ITS rRNA gene sequence analyses revealed that this morphotype evolved independently both in the Chlorella and Parachlorella clades of the

Phylogenetic relationship of Chlorella and Parachlorella gen. nov. (Chlorophyta, Trebouxiophyceae)
Phycologia, 2004Abstract Chlorella is one of the archetypical forms of coccoid green algae and one of the best-studied phototrophic eukaryotes. However, its systematics remains enigmatic due to conflicts between morphological and molecular phylogenetic approaches. The sequences of the 18S ribosomal RNA gene of nine strains of Chlorella and related taxa, and the ITS2 ...

The new species Asterochloris sejongensis sp. nov. has been collected from four localities of King George Island, Antarctica, and is described as a phycobiont of the lichen species Cladonia pyxidata and Sphaerophorus globosus. This discovery is based on morphological and molecular data obtained using light microscopy, confocal laser microscopy ...

Journal of Phycology, 2017
The family Oocystaceae (Chlorophyta) is a group of morphologically and ultrastructurally distinct green algae that constitute a well‐supported clade in the class Trebouxiophyceae. Despite the family's clear delimitation, which is based on specific cell wall features, only a few members of the Oocystaceae have been examined using data other than ...

Systematika zelených kokálních řas tříd Chlorophyceae a Trebouxiophyceae
2020Aim of the review part is to summarize a current situation in the systematics of the green coccal algae, which were traditionally assembled in only one order: Chlorococcales. Their distribution into the lower taxonomical unites (suborders, families, subfamilies, genera) was based on the classic morphological criteria as shape of the cell and ...
