Photosynthetic euglenids (Euglenophyta) are a monophyletic group of unicellular eukaryotes characterized by the presence of plastids, which arose as the result of the secondary endosymbiosis. Many Euglenophyta plastid (pt) genomes have been characterized recently, but they represented mainly one family – Euglenaceae. Here, we report a comparative analysis of plastid genomes from eight representatives of the family Phacaceae. Newly sequenced plastid genomes share a number of features including sy...

BACKGROUND:Over the last few years multiple studies have been published showing a great diversity in size of chloroplast genomes (cpGenomes), and in the arrangement of gene clusters, in the Euglenales. However, while these genomes provided important insights into the evolution of cpGenomes across the Euglenales and within their genera, only two genomes were analyzed in regard to genomic variability between and within Euglenales and Eutreptiales. To better understand the dynamics of chloroplast g...

Euglena sanguinea is known to produce the alkaloid toxin euglenophycin and is known to cause fish kills and inhibit mammalian tissue and microalgal culture growth. An analysis of over 30 species of euglenoids for accumulation of euglenophycin identified six additional species producing the toxin; and six of the seven E. sanguinea strains produced the toxin. A phylogenetic assessment of these species confirmed most taxa were in the Euglenaceae, whereas synthesis capability apparently has been los...

Over the last few years multiple studies have been published outlining chloroplast genomes that represent many of the photosynthetic euglenid genera. However, these genomes were scattered throughout the euglenophyceaean phylogenetic tree, and focused on comparisons with Euglena gracilis. Here, we present a study exclusively on taxa within the Euglenaceae. Six new chloroplast genomes were characterized, those of Cryptoglena skujai, E. gracilis var. bacillaris, Euglena viridis, Euglenaria anabaena...

Photosynthetic euglenids acquired chloroplasts by secondary endosymbiosis, which resulted in changes to their mode of nutrition and affected the evolution of their morphological characters. Mapping morphological characters onto a reliable molecular tree could elucidate major trends of those changes. We analyzed nucleotide sequence data from regions of three nuclear-encoded genes (nSSU, nLSU, hsp90), one chloroplast-encoded gene (cpSSU) and one nuclear-encoded chloroplast gene (psbO) to estimate ...

Since its creation in 1917 the genus Cyclidiopsis, and its validity, has been a source of debate among euglenid taxonomists. While many authors have supported its legitimacy, various other authors have considered it to be a subgenus of Astasia or even promoted its complete dissolution. In this study, we have sequenced the small subunit and large subunit ribosomal DNA of Cyclidiopsis acus, the type species for the genus. Subsequent phylogenetic analyses showed that C. acus grouped with taxa from ...

ABSRTACT: The phylum Rhodophyta contains of a wide range of ecologically and economically important species distributed worldwide. One taxon, Gracilaria salicornia, was an introduced and invasive species in the Hawaiian Islands that had displaced native flora and fauna, and caused widespread ecological damage. We presented the chloroplast and mitochondrial genomic sequences of G. salicornia from Hawaiian material and compared them to sequences of closely related species. We found that the gene c...

Euglena proxima is a common, globally dispersed, and easily identified photosynthetic euglenoid. Previous phylogenetic analyses using nuclear-encoded small subunit (SSU) and large subunit (LSU) rRNA genes revealed that this taxon was paraphyletic with other Euglena species and was positioned as sister to all Euglenaceae. Despite this, authors were reluctant to remove this taxon from Euglena until additional data, or taxa pairing with E. proxima, were obtained because it created a monotypic genus...
