TL;DR: The phylogenetic position of Koliella, a chlorophyte characterized by Klebsormidium type cell division, was inferred from analyses of partial 18S r DNA and partial 16S rDNA, and high decay indices and bootstrap values supported high affinity for Trebouxiophyceae, however, the genus appeared to be polyphyletic.

TL;DR: Combining datasets resolved the relationships among ten genera of photosynthetic euglenoids by using Maximum Likelihood and Bayesian analyses of three genes, nuclear SSU and LSU rDNA, and chloroplast SSU (cpSSU) rDNA.

TL;DR: The data clearly indicate that a substantial revision of euglenoid systematics is very much required, nevertheless it must await while more information can be gathered, allowing resolution of outstanding relationships.

TL;DR: 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.

TL;DR: Morphological and molecular studies, as well as original literature reexamination, necessitate establishment of five Euglena species with a single axial, stellate chloroplast, allowing distinction of the considered species.
