The chlorarachniophytes are a small group of marine amoeboflagellate and flagellate algae that acquired photosynthesis by engulfing a green alga and keeping its plastid. The nucleus of the green algal endosymbiont (called the nucleomorph) persists in a highly reduced form between the inner and outer plastid membrane pairs (see Gilson & McFadden 1999 (Phycol. Res. 47, 7-) and references therein for review). The host component of chlorarachniophyte cells appears to be related cercomonads, plasmodiophorids and the foraminiferans (Keeling 2001. Mol. Biol. Evol. 18, 1551-; Archibald et al., 2003. Mol. Biol. Evol. 20, 62). Click here to learn more.
