Intron insertion sites in <i>M. aenigmatica</i> that are shared with other euglenid plastid DNAs.

aIntron insertion sites reported to display twintrons in Euglena gracilis are highlighted in bold. bMaen, Monomorphina aenigmatica; Egra, Euglena gracilis; Elon, Euglena longa; Evir, Eutreptia viridis; Egym, Eutreptiella gymnastica. The number corresponds to the insertion site on the gene (labelled from 5′ to 3′). cThe sequence of the rps18.Egym.1 intron is different from those in M. aenigmatica and E. gracilis and may be unrelated.
