Paralytic shellfish toxin (PST) content in the dinoflagellate Gymnodinium catenatum changes with culture age, with a higher toxin concentration in the logarithmic phase that decreases when the culture ages. The gene copy number (GCN) of domains sxtA1 and sxtA4 was higher in the lag and stationary phase, and lag phase, respectively. No relationship was found between the GCN of the domains sxtA4 and sxtA1 with the PST content in G. catenatum.
麻痹性贝类毒素（PST）在甲藻鳍藻中的含量随培养年龄而变化，对数期的毒素浓度较高，随着培养年龄的增加而降低。sxtA1 和 sxtA4 结构域的基因拷贝数（GCN）在滞后期和静止期较高，分别在滞后期。sxtA4 和 sxtA1 结构域的 GCN 与鳍藻中 PST 含量之间没有关系。
