A
phylogenetic analysis of the Prorocentrum species is
presented, that includes the sequences of the large and
small ribosomal RNA subunits from 19 cultures from 13 of the
20 species reported in the Pacific coast of Mexico; the
results showed that P. micans, P. gracile and
P. mexicanum were the closest of species, that
planktonic may be more recent than epibenthonic species and
it is suggested that the probable ancestor of the
Prorocentrum genus could be a round cell without apical
spine, toxic and epibenthonic.
Key words: Prorocentrum, parsimony analysis,
dinoflagellates, LSUrDNA, SSUrDNA |
