In particular, all studies concluded that the main strength in the use of hemp-based materials comes from the production phase because of the "green" origin of these materials, mainly associated with the carbon sequestration during plantation growth.
While Heterolobosea and Euglenozoa are often united as the morphologically defined taxon, Discicristata, within Excavata [ 10], recent morphological and molecular phylogenetic analyses suggest that the heteroloboseans (e.g. Naegleria) never possessed the secondary plastid of green lineage and share the same origin with Euglenida [ 43].
This phylogenetic relationship and the lack of CYP97B homologs in C. merolae point to a "green" origin of this gene in Chromalveolates, similar to the origin and evolution of hydroxypyruvate reductase [ 79].
But it is presented as some bright new progressive gem, with never a mention of its green origins.
Interestingly, we found that the TIM genes from the chlorarachniophyte Bigelowiella natans, a member of another algal lineage harboring secondary plastid of green algal origin, were also nested within the red algal clade (Additional file 2: Supplementary fig. S15A).
The genus Lepidodinium is the only known dinoflagellate lineage that possesses a secondary plastid of green algal origin rather than the red algal derived peridinin-containing plastid found in most photosynthetic dinoflagellates [ 22- 24, 37].
Some of these were of green algal origin.
Euglena species differ from their closest relatives in that they contain a secondary plastid of green algal origin [ 50].
In this study, we decided to extend this hypothesis to the flagellate E. gracilis possessing secondary chloroplasts of green algal origin.
The nucleomorphs of these two groups have independent origins: the cryptomonad plastid and nucleomorph are of red algal ancestry [ 5, 6] whereas the chlorarachniophyte plastids and nucleomorphs are of green algal origin [ 7, 8].
