 | | Results of preliminary phylogenetic analyses of nuclear and plastid DNA coding regions show that one of the major orders of the Bangiophycidae, the Porphyridiales, is split into at least three different lineages and that the Florideophycidae is monophyletic with weak support for an origin from the Bangiales (Fig. |
 | | We have determined that the plastids of the Heterokonta are likely derived from members of the Cyanidiales and are not directly related to the plastids in the Cryptophyta and the Haptophyta. |
 | | Secondary plastids in the Cryptophyta, Haptophyta, and Heterokonta have polyphyletic |
