Intrageneric chloroplast genome comparison in the genus Euglena (Phylum: Euglenophyta) with annotated chloroplast genomes of Euglena hiemalis and Euglena clara

The genus Euglena is composed of six subclades with a diversity of chloroplast morphologies, unlike that found in the other genera of Euglenaceae. This genus contains five published chloroplast genomes (cpGenome) and the colorless plastid genome (ptGenome) of the non-photosynthetic euglenoid Euglena longa within the same subclade as Euglena gracilis. Previous studies of cpGenomes revealed that Euglena viridis and E. gracilis, although in...
