Abstract

Abstract

The 18S rRN Agenes of "red-tide" related Phaeocystis sp.from the southeast coast of China,and its related species P.globosa and P.pouchetii are sequenced.Phylogenetic trees are constructed by using these 18S rDNA sequences.It is clearly shown that Phaeocystis sp.from the southeast coast of China is remarkably similar to several isolates of P.globosa rather than P.p ouchetii.The results demonstrate that the bloom-forming species of Phaeocystics most likely originated from an endemic warm-water species.The phenotypes of different members of the genus Phaeocystis are variable,apparently changing in response to environmental conditions.
