The toxigenic genus Alexandrium includes ∼30 species, but information about its biogeography at a regional scale is limited. In this study, we explored the diversity of Alexandrium along the coast of China by incubating resting cysts collected from 7

The frequency of harmful algal blooms (HABs) has increased in China in recent years. Information about harmful dinoflagellates and paralytic shellfish toxins (PSTs) is still limited in China, especially in the Beibu Gulf, where PSTs in shellfish have

To improve labeling-intensity of whole-cell fluorescence in situ hybridization (FISH) in the molecular identification of toxic Alexandrium tamiyavanichii, two DNA probes (TAMID2 plus TAMIS1 designed from the LSU and SSU rDNA regions, respectively) were

Paralytic shellfish poisoning (PSP) is one of the most important types of algal-origin shellfish poisoning in Southeast Asia countries, with no exception to Malaysia. In Malaysia, incidents of PSP due to the marine dinoflagellate Pyrodnium bahamense have

The phylogenetic relationship of the thecate PSP-toxin producing dinoflagellate Alexandrium tamiyavanichii Balech to other species of Alexandrium was studied based on nucleotide sequences of the ITS1, ITS2, 5.8S, 18S and 28S subunits of the ribosomal
