Additional file 7 of Globins in the marine annelid Platynereis dumerilii shed new light on hemoglobin evolution in bilaterians

Additional file 7: List of additional globin protein sequences, from non bilaterian metazoans (Aurelia aurita, Clytia hemisphaerica, Hydra vulgaris, Amphimedon queenslandica, Mnemiopsis leydyi), one acoel (Symsagittifera roscoffensis), and two choanoflagellates (Salpingoeca rosetta, Monosiga brevicollis). The two globins from the acoel are extracted from a transcriptome [18]. Acoels are part of Xenacoelomorpha, a group of worms that has been proposed to be the sister-group of all remaining bilaterians [79]. This view remains however challenged as they are also proposed to belong with the deuterostomes [80]. Choanoflagellates are a group of eukaryots closely related to metazoans, that had been reported to possess neuroglobin-like proteins [18].
