具有鱼类毒性的鞭毛虫查托氏菌 (Chattonella marina) 会产生极高水平的活性氧 (ROS) 超氧化物，其部分受到光合电子转移捐赠的电子的控制。我们证明使用光合作用阻断除草剂 DCMU 可以显着减少 ROS。由于超氧化物被认为是造成 C. marina 毒性的一个因素，因此鱼类死亡率在白天可能更为突出。
The ichthyotoxic flagellate Chattonella marina produces extraordinary levels of the reactive oxygen species (ROS) superoxide, which is partially controlled by electrons donated through photosynthetic electron transfer. We demonstrate that ROS can be significantly reduced using the photosynthesis blocking herbicide DCMU. As superoxide is considered a contributor to the toxicity of C. marina, fish mortality may be more prominent during daylight hours.
