To establish taxonomy and understand phylogenetic relationships among strains and species of the photosynthetic euglenoids, we performed phylogenetic analyses based on a four gene sequence dataset (nr SSU and LSU rDNA, and pt SSU and LSU rDNA) from 343 taxa (including three outgroup). The phylogenetic tree based on the combined dataset was split into two major clades: Euglenaceae and Phacaceae. The family Euglenaceae was a well-supported monophyletic group containing eight genera (Colacium, Cryp...

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...

Because they represent the earliest divergences of the Chlorophyta and include the smallest known eukaryotes (e.g., the coccoid Ostreococcus), the morphologically diverse unicellular green algae making up the Prasinophyceae are central to our understanding of the evolutionary patterns that accompanied the radiation of chlorophytes and the reduction of cell size in some lineages. Seven prasinophyte lineages, four of which exhibit a coccoid cell organization (no flagella nor scales), were uncovere...

Euglenids are a group of protists that comprises species with diverse feeding modes. One distinct and diversified clade of euglenids is photoautotrophic, and its members bear green secondary plastids. In this paper we present the plastid genome of the euglenid Eutreptiella, which we assembled from 454 sequencing of Eutreptiella gDNA. Comparison of this genome and the only other available plastid genomes of photosynthetic euglenid, Euglena gracilis, revealed that they contain a virtually identica...

Background Synonymous DNA substitution rates in the plant chloroplast genome are generally relatively slow and lineage dependent. Non-synonymous rates are usually even slower due to purifying selection acting on the genes. Positive selection is expected to speed up non-synonymous substitution rates, whereas synonymous rates are expected to be unaffected. Until recently, positive selection has seldom been observed in chloroplast genes, and large-scale structural rearrangements leading to gene dup...

Abstract Gene transfer events from organelle genomes (mitochondria and chloroplasts in plants) to the nuclear genome are important processes in the evolution of the eukaryotic cell. It is highly likely that the gene transfer event is still an ongoing process in higher plant mitochondria and chloroplasts. The number and order of genes encoded in the chloroplast genome of higher plants are highly conserved. Recently, several exceptional cases of gene loss from the chloroplast genome have been disc...

Abstract Two new and important features of introns have emerged from analysis of the Euglena gracilis chloroplast genome. One is a new class of introns, designated group III, that may be the closest contemporaries to nuclear pre-mRNA introns. The second is introns that are interrupted by other introns termed twintrons.

The chloroplast genome of Eutreptia viridis Perty, a basal taxon in the photosynthetic euglenoid lineage, was sequenced and compared with that of Euglena gracilis Ehrenberg, a crown species. Several common gene clusters were identified and gene order, conservation, and sequence similarity was assessed through comparisons with Euglena gracilis . Significant gene rearrangements were present between Eutreptia viridis and Euglena gracilis chloroplast genomes. In addition, major expansion has occurre...

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...

Abstract Podocarpaceae is the largest family in cupressophytes (conifers II), but its plastid genomes (plastomes) are poorly studied, with plastome data currently existing for only four of the 19 Podocarpaceous genera. In this study, we sequenced and assembled the complete plastomes from representatives of eight additional genera, including Afrocarpus, Dacrydium, Lagarostrobos, Lepidothamnus, Pherosphaera, Phyllocladus, Prumnopitys, and Saxegothaea . We found that Lagarostrobos, a monotypic genu...

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...
