Comments Unlike the vast majority of cercozoans, chlorarachniophytes are photosynthetic, having acquired a plastid by secondary endosymbiosis of a green alga. The secondary endosymbiont of chlorarachniophytes is also noteworthy because it has retained its nucleus and genome in a highly reduced form known as a nucleomorph. The B. natans chloroplast genome maps as a circle of 69,166 bp. Note-for smaller non-photosynthetic plastid genomes see fig. 3 p. 58
