    Abstract:

    In order to understand the causes of algae bloom in Beibu Gulf, the sequences of ribosome 18S rDNA of Phaeocystis were cloned by PCR. The results showed that the strains from Beibu Gulf had single-celled and group structures, and their sequences of ribosome 18S rDNA showed 99%-100% homology to those Phaeocystis globosa in NCBI GenBank. The strains from Beibu Gulf and Phaeocystis globosa with different origins get together in a big clade in the phylogenetic tree, the genetic distance with Phaeocystis globosa was less than that with other species of Phaeocystis. Therefore, it was confirmed for the first time that the strains of Phaeocystis in Beibu Gulf caused algal bloom belonged to Phaeocystis globosa.
