ABSTRACT. Chlorarachniophytes are flagellated and/or reticulopod-forming marine algae with chlorophyll a- and b-containing plastids
of secondary endosymbiotic origin. They are one of only two algal groups known to possess a ``nucleomorph'' (i.e. the remnant nucleus of
the eukaryotic endosymbiont that donated the plastid). Apart from the recently sequenced nucleomorph genome of Bigelowiella natans,
little is known about the size, structure, and composition of chlorarachniophyte nucleomorph genomes. Toward the goal of better un-
derstanding nucleomorph genome diversity, as well as establishing a phylogenetic framework with which to interpret variation in
