Previous studies using the nuclear SSU rDNA and partial LSU rDNA have demonstrated that the euglenoid loricate taxa form a monophyletic clade within the photosynthetic euglenoid lineage. [] Key Method In order to determine the relationships among the loricate taxa, SSU and LSU nuclear rDNA sequences were obtained for eight Strombomonas and 25 Trachelomonas strains and combined in a multigene phylogenetic analysis.

MULTIGENE ANALYSES OF PHOTOSYNTHETIC EUGLENOIDS AND NEW FAMILY, PHACACEAE (EUGLENALES) 1

The family Euglenaceae is proposed to be limited to the members of the Euglena clade and a new family, the Phacaceae, to house the genera Phacus, Lepocinclis, and Discoplastis is proposed.

Cryptic Speciation in the Genus Cryptoglena (Euglenaceae) Revealed by Nuclear and Plastid SSU and LSU rRNA Gene

Three new species are proposed based on specific molecular signatures and gene divergence of the nr SSU rDNA sequences of Cryptoglena, including C. soropigra, C. similis, and C. longisulca.

Phylogeny of Trachelomonas and Strombomonas (Euglenaceae) Based on Morphological and Molecular Data

It was found that the shape of the loricae and the presence or absence of thecollar were relatively stable in culture, while the length of the collar presence or presence of spines and the color of theLoricae changed, which supported Trachelomonas and Strombomonas as independent genera.

Taxon-rich multigene phylogeny of the photosynthetic euglenoids (Euglenophyceae)

To establish taxonomy and understand phylogenetic relationships among strains and species of the photosynthetic euglenoids, phylogenetic analyses based on a four gene sequence dataset from 343 taxa from 343Taxa were performed.

Phylogenetic Relationships and Morphological Character Evolution of Photosynthetic Euglenids (Excavata) Inferred from Taxon‐rich Analyses of Five Genes

This research indicated that pyrenoids were lost twice during the evolution of phototrophic euglenids, and that mucocysts, which only occur in the genus Euglena, evolved independently at least twice.

Contemporary integrative taxonomy for sexually deprived protists: A case study of Trachelomonas (Euglenaceae) from western Ukraine

Biological material was used to epitypify three names of Trachelomonas, eternally linking morphology with reliable genetic information, one of the powerful methods to clarify ambiguous scientific names, which has particular importance in character‐poor protists such as the euglenophytes.

Phylogeny and Classification of Euglenophyceae: A Brief Review

This article summarizes recent advances in the phylogeny and classification of the phototrophic euglenids, aiming at understanding the situation of the group within the phylum Euglenozoa, as well as its evolutionary relationships and the changes in its taxonomic classification.

Towards a molecular phylogeny of the Euglenozoa: analyses of ribosomal DNA sequences and deduced secondary structure elements

Important findings concerning the phylogeny of major euglenozoan groups have been found, i.e. the existence of a eugLenozoa crown group was confirmed by phylogenetic as well as spectral analyses and according to the eponymous autapomorphy, a helically pellicle pattern, prior taxon denominations were converted into Helicales taxon nov.

PHYLOGENY OF EUGLENOPHYCEAE BASED ON SMALL SUBUNIT rDNA SEQUENCES: TAXONOMIC IMPLICATIONS 1

Small subunit rDNA sequences of 42 taxa belonging to 10 genera were used to infer phylogenetic relationships among euglenoids and the strong support for the individual clades confirmed the value of using lorica features as taxonomic criteria.

Phylogenetic analyses of various euglenoid taxa (euglenozoa) based on 18s rdna sequence data

All trees derived from SSU rRNA data strongly supported the monophyletic origin of the Euglenozoa, with kinetoplastids as sister clade to the euglenoids and Petalomonas cantuscygni Cann et Pennick diverging at the base of the monophysletic eUGlenoid lineage.

Phylogeny and taxonomic revision of plastid-containing euglenophytes based on SSU rDNA sequence comparisons and synapomorphic signatures in the SSU rRNA secondary structure.

Sequence comparisons and a revised classification of the Euglenophyceae were based on 92 new SSU rDNA sequences obtained from strains of Euglena, Astasia, Phacus, Trachelomonas, Colacium, Cryptoglena, Lepocinclis, EUTreptia, Eutreptiella and TetreutrePTia, and one lineage was recognized as the previously neglected genus Monomorphina Mereschkowsky (1877).

MORPHOLOGICAL SEPARATION OF THE EUGLENOID GENERA TRACHELOMONAS AND STROMBOMONAS (EUGLENOPHYTA) BASED ON LORICA DEVELOPMENT AND POSTERIOR STRIP REDUCTION 1

Two sets of morphological characters, lorica development and pellicle strip reduction, support the separation of Trachelomonas and Strombomonas as distinct genera.

PHYLOGENY OF THE EUGLENALES BASED UPON COMBINED SSU AND LSU RDNA SEQUENCE COMPARISONS AND DESCRIPTION OF DISCOPLASTIS GEN. NOV. (EUGLENOPHYTA) 1

This study demonstrated that increased taxon sampling, multiple genes, and combined data sets provided increased support for internal nodes on the euglenoid phylogenetic tree and resolved relationships among the major genera in the photosynthetic eUGlenoid lineage.

Phylogeny of the photosynthetic euglenophytes inferred from the nuclear SSU and partial LSU rDNA.

The addition of the LSU rDNA dataset to the euglenophyte phylogeny supports the view that the genera Euglena, Lepocinclis and Phacus are not monophyletic and substantiates the existence of several well-supported clades.

Phylogenetic position and inter-relationships of the osmotrophic euglenids based on SSU rDNA data, with emphasis on the Rhabdomonadales (Euglenozoa).

The inter-relationship of the three distinct euglenozoan taxa (euglenids, kinetoplastids and diplonemids) could not be convincingly resolved by this study.

PHYLOGENY OF PHOTOSYNTHETIC EUGLENOPHYTES BASED ON COMBINED CHLOROPLAST AND CYTOPLASMIC SSU RDNA SEQUENCE ANALYSIS 1

The combined data set produced several additional well‐supported clades, not encountered before in the analyses of green euglenoids, there are three main well‐defined clades (A, B/C/D, and G) on trees from the combinedData set.

Phylogenetic analysis of phagotrophic, photomorphic and osmotrophic euglenoids by using the nuclear 18S rDNA sequence.

Phylogenetic analyses of 35 strains carried out using the SSU rDNA suggest that neither the Euglenales nor the Eutreptiales form a monophyletic lineage, thus questioning currently available classifications.

PLASTID MORPHOLOGY, ULTRASTRUCTURE, AND DEVELOPMENT IN COLACIUM AND THE LORICATE EUGLENOPHYTES (EUGLENOPHYCEAE) 1

Developmental patterns of plastid replication also suggest that these five taxa share recent common ancestry with members of the genus Euglena subgenus Calliglena.
