 | | As LSU sequences for Perkinsus, Oxyrrhis, Syndiniales, Noctilucales or Blastodiniales are unavailable, the trees consisted of a large, badly resolved group of very short-branched taxa (the GPP complex, Gymnodiniales, Peridiniales, Prorocentrales and Dinophysiales) and a monophyletic grouping of longer-branched members of the order Gonyaulacales (Fig. |
 | | In the most recent general classification of dinoflagellates (Fensome et al., 1993) Noctilucales and Blastodiniales are basal classes of their own within the subdivision of dinokaryotic dinoflagellates. |
 | | As a consequence, the basal position of Noctiluca within the dinokaryotic dinoflagellates should be reexamined: the two main arguments for proposing such a basal position have been shown to be either very weak (SSU-based phylogenetic analyses), or probably wrong (the ostensible presence of histones in the nuclei of feeding stages). |
