The SSU and partial LSU regions of the isolated material were deposited in to the Gen Bank and the accession numbers are given in Table 1.Fifty Cladophora specimens examined,a total of 13 ribotypes were detected(Table 1).The alignments of the two ribosomal genes,SSU and partial LSU,were 1 417 bp and 495 bp in length,respectively.The SSU fragment was approximately three times as long as the partial LSU region but it contained about the same number of variable and parsimony-informative characters(SSU:322/144;LSU:330/155).It seems that the pairwise sequence divergence in the SSU was significantly lower than in the LSU(Leliaert et al.,2007).The alignment of SSU sequences and partial LSU sequences was 1 912 bp in length,including 282 parsimony-informative sites among651 variable sites.The pairwise distances between studies haplotypes were less than 2%both in SSU and partial LSU sequences.No significant saturation was tested in either SSU or LSU regions,according to the Iss statistic(Xia&Xie,2001).
