Abstract

The partial sequences of the large subunit (24S) ribosomal RNA gene(LsurRNA) of three Alexandrium catenella strains isolatedduring the 1998 and 1989 red tide incidents in Hong Kong were compared,togetherwith the sequences of other Asian A. catenella speciescomplex. The sequences of two A. catenella strainsisolatedin 1998 were identical, despite being isolated at different time (March andApril) and different locations (eastern and southern Hong Kong). In cladisticanalysis, the two A. catenella HK98A & B strains, theA. catenella HK1989 strain, the Chinese strain clade andtheKorean/Japanese A. catenella form a clade distinct fromother A. catenella strains. Interestingly, the twoA. catenella HK98A & B strains only form a clade withtheA. catenella HK1989 strain/ChineseA. catenella (CCMP1493) with low bootstrap values (49%).
