Phylogenetic relationships of amidinotransferase inferred using the maximum likelihood method. The analysis was based on partial saxitoxin gene [sxtA (A), sxtG (B)] sequences (150–250 bp). S-clone and W-clone indicate that the taxon was sampled from the sediment (S) and water column (W), respectively. The saxitoxin-producing gene of Alexadrium spp. was used as an out-group for the purpose of rooting the analysis. Bootstrap values of 20–49% are shown as a quadrisection, 50–98% are shown as a half circle, and 99–100% are shown as a complete circle to the left of the internal nodes. Evolutionary analyses were conducted in MEGA 6.0. Square and triangle marker indicates clones detected from water and sediment sample, respectively
