• ArchaeplastidaRelated: Its genes and bacterial affinities preserve evidence of plastid ancestry.

• Primary endosymbiosisRelated: Its bacterial-like genes provide evidence of the plastid’s former independent ancestry.

• ChromalveolataRelated: Comparisons of plastid genes helped test whether the proposed lineages shared a red-algal plastid ancestor.
