International Journal of Systematic and Evolutionary Microbiology, 2016 Coccoid green algae are extremely diverse despite their simple coccoid phenotype, a phenotype that may be the result of convergent evolution. In this study, we used a polyphasic approach combining molecular phylogenetic analyses, morphology and ...

Arsenolipids in the green alga Coccomyxa (Trebouxiophyceae, Chlorophyta)
Phytochemistry, 2019Lipid-like compounds containing a dimethylarsinoyl group, i.e. Me2As(O)-, have been identified by liquid chromatography/inductively coupled plasma mass spectrometry (LC/ICP-MS) and non-aqueous reversed-phase high-performance liquid chromatography (positive and/or negative high-resolution tandem electrospray ionization mass spectrometry (NARP-HPLC/HR ...

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 ...

Genotype versus Phenotype Variability in Chlorella and Micractinium (Chlorophyta, Trebouxiophyceae)
Protist, 2006The most recent revision of the genus Chlorella, based on biochemical and SSU rDNA analyses, suggested a reduction to a set of four "true" spherical Chlorella species, while a growing number of morphologically different species such as Micractinium (formerly Micractiniaceae) were found to cluster within the clade of "true"Chlorella.

Siderocelis irregularis (Chlorophyta, Trebouxiophyceae) in Lake Tanganyika (Africa)
Biologia, 2008Siderocelis irregularis Hindak, representing a genus Siderocelis (Naumann) Fott that is known from European temperate waters, was identified as a common phytoplankter in Lake Tanganyika. It was found aposymbiotic as well as ingested (possibly endosymbiotic) in lake heterotrophs, mainly Strombidium sp. and Vorticella spp.

Isolation and characterization of new Botryococcus braunii (Trebouxiophyceae) isolates
Renewable Energy, 2019Abstract Four isolates of Botryococcus braunii Kutzing were isolated from the Nile River in Egypt. The morphological examinations and results of 5.8S rRNA gene sequences confirmed that EG-Bb01 (JN580448.1), EG-Bb02 (JN580449.1), EG-Bb03 (JN580450.1) and EG-Bb04 (JN580451.1) are B. braunii.

Studies on uroporphyrinogen decarboxylase fromChlorella kessleri(Trebouxiophyceae, Chlorophyta)
Canadian Journal of Microbiology, 2007Uroporphyrinogen decarboxylase (UroD) (EC 4.1.1.37) is an enzyme from the tetrapyrrole biosynthetic pathway, in which chlorophyll is the main final product in algae. This is the first time that a study on UroD activity has been performed in a green alga ( Chlorella ).

Planta, 2007
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.

Evidence for mixotrophy in pico‐chlorophytes from a new Picochlorum (Trebouxiophyceae) strain
Journal of Phycology, 2021Mixotrophs are increasingly recognized for their wide distribution in aquatic ecosystems and significant contributions to biogeochemical cycling. Many taxa within the phyla Chrysophyta, Cryptophyta, and Haptophyta are capable of phago‐mixotrophy, however, phagotrophy in the Chlorophyta remains controversial due to insufficient research and solid ...

Cell ReportsTrebouxiophyceae, with its morphological and ecological diversity, is the ideal candidate for tracing the origin and evolution of green algae, yet its phylogeny and diversification timeline remain unresolved. Our high-density taxa and large-scale nuclear gene sampling confirm its monophyly, dividing it into the core trebouxiophyceans clade and the ...
