Ultrastructure of Euglena anabaena var. minor (Euglenophyceae)
Phycological Research, 2000SUMMARY The freshwater green euglenoid Euglena anabaena var. minor has a pellicle with groove-ridge articulation, a chloroplast with pyrenoids doubly sheathed by two paramylon caps, and a nucleus with permanently condensed chromosomes and nucleolus. The flagellar apparatus basically resembles that of Euglena.

During a survey for marine microalgal resources, we isolated a rare marine euglenoid from the coastal waters of Qingdao, China in 2009, and established a pure culture. Electron microscopic and molecular phylogenetic (18S rDNA and 16S rDNA sequences) analyses revealed a close affinity with Eutreptiella gymnastica, a bloom-forming species.

Abstract Endonuclear bacteria were observed within Euglena hemichromata cells isolated from a bloom in a small pond in South Korea. Ultrastructural features of the host cell and resident bacteria are presented and a route of infection pathway into host cells proposed.

PARAMYLON SYNTHESIS IN HETEROTROPHIC AND PHOTOHETEROTROPHIC EUGLENA (EUGLENOPHYCEAE)1
Journal of Phycology, 1980ABSTRACTGrowth of Euglena gracilis Klebs in medium containing DL‐lactate as sole carbon source results in the synthesis of large quantities of paramylon at the beginning of exponential growth. The accumulation of paramylon grains in the cytoplasm is observable in both dark‐grown and light‐grown cells.

ULTRASTRUCTURE OF THE RESERVOIR AND FLAGELLA IN PHACUS PLEURONECTES (EUGLENOPHYCEAE)1
Journal of Phycology, 1975SUMMARYThe ultrastructure of the reservoir region of Phacus pleuronectes is described. Thin sections, ruthenium red staining, and shadow‐cast preparations elucidate relationships and structural details of the flagella and flagellar hairs or mastigonemes.

Biodiversity of Euglenophyceae in Safilguda Lake, Hyderabad, India
International Journal on AlgaeThis paper presents a study of <i>Euglenophyceae,</i> in Safilguda Lake. For this purpose, physicochemical parameters were analyzed in water samples obtained from three sampling stations in the lake between May 2017 to April 2018. Statistical tests were used to establish the link between phytoplankton and physico-chemical variables ...

Envelopes of the euglenoid flagellate,Trachelomonas lefevrei may range in color from hyaline to golden to dark brown and may be variously ornamented with spines, papillae and puncta. Elemental composition affects both envelope color and microarchitecture, which may be granular and/or microcrystalline.

Journal of Eukaryotic Microbiology, 2008
ABSTRACT. Two different length cDNAs encoding triosephosphate isomerase (TIM) were identified in the two trophic modes of euglenoids, the phototrophic Euglena gracilis and Euglena intermedia and the saprotrophic Astasia longa. Sequence analyses and presequence prediction indicated that the shorter cDNA encodes a cytosolic TIM and the longer cDNA ...

Redescription of Euglena rustica (Euglenophyceae), a rare euglenophyte from the intertidal zone
Phycologia, 2002Abstract Euglena rustica, a rare species of Euglena, was discovered growing in patches in the intertidal sand of Nannygoat Beach at the University of Georgia Marine Institute at Sapelo Island, Georgia. A full-emended description is given. The cells are ~ 50 μm long, and the posterior is never attenuate.

HISTOCHEMICAL STUDIES OF THE EXTRACELLULAR CARBOHYDRATE OF COLACIUM MUCRONATUM (EUGLENOPHYCEAE)1
Journal of Phycology, 1977ABSTRACTThe stalk of Colacium mucronatum Bourr. & Chad. is composed primarily of a cylindrical shaft with a lightly staining inner core and diffuse peripheral cortex. The shaft and cortex arise from a ring‐shaped region around the canal opening whereas the core appears continuous with the canal which may be associated with initial cell attachment ...
