生物发光闪烁对于萤火虫的繁殖是必不可少的，然而控制光产生的具体分子机制还不是很清楚。我们报道了在氧气存在的情况下，一氧化氮(NO)气体可以刺激萤火虫的光产生，没有清道夫阻止神经递质章鱼胺诱导的生物发光，在位于神经末梢和发光细胞之间的细胞中，NO合成酶在萤火虫灯笼中强健表达，这些结果表明，NO的合成是萤火虫闪光控制的关键决定因素。
Bioluminescent flashing is essential for firefly reproduction, yet the specific molecular mechanisms that control Light production are not well understood. We report that Light production by fireflies can be stimulated by nitric oxide (NO) gas in the presence of oxygen and that NO scavengers block bioluminescence induced by the neurotransmitter octopamine, NO synthase is robustly expressed in the firefly Lantern in cells interposed between nerve endings and the light-producing photocytes, These results suggest that NO synthesis is a key determinant of flash control in fireflies.
