摘      要：Some benthic Prorocentrum can produce okadaic acid(OA)and dinophysistoxins(DTXs)that cause diarrheic shellfish poisoning(DSP)in *** diversity and toxin profi les(OA and DTXs)of benthic Prorocentrum were investigated in the Xisha Islands,South China *** benthic Prorocentrum was identified by both morphological features and molecular *** were examined by light,fluorescence,and scanning electron microscopy,and phylogenetic analyses were based on partial large subunit(LSU)rDNA and ITS1-5.8S-ITS2(ITS)*** Prorocentrum species including ***,***,***,***,***,*** complex,and *** were identified in Xisha *** them,*** and *** were recorded in Chinese waters for the first *** and DTXs contents of seven benthic Prorocentrum species were evaluated based on liquid chromatography-tandem mass spectrometry(LC-MS/MS).All Xisha Islands strains of *** complex produced OA at contents ranging from 1663 to 3816 fg/*** also generated OA at 407 fg/cell,but other five species had no detectable ***,interestingly,two strains of *** complex produced DTX-1 only(74 and 183 fg/cell)and another two strains generated an isomer of OA and *** findings provided insight into the biodiversity of benthic Prorocentrum in the Xisha Islands and pointed out the potential risk of DSP in this area.
