我们研究了除草剂噻苯威对海洋海链藻生长、光合活性和光合作用相关蛋白表达谱的影响。在浓度为1.26 mg/L时，生长速率被抑制50%。在5 mg/L浓度下，生长和光系统II活性（Fv/Fm ratio）显著降低，其中13种蛋白的表达量显著增加，11种蛋白的表达量显著降低。在这些蛋白质中，Rieske铁硫蛋白的水平降低至不到对照水平的一半。这种蛋白质是光合作用电子传递链中细胞色素b6 f复合物的重要组成部分。虽然硫代苯威降低Rieske铁硫蛋白水平的机制尚不清楚，但这些结果表明，硫代苯威中断光合电子传递链抑制了生长。© 2013 Wiley Periodicals，Inc.

We investigated the effects of the herbicide thiobencarb on the growth, photosynthetic activity, and expression profile of photosynthesis‐related proteins in the marine diatomThalassiosira pseudonana. Growth rate was suppressed by 50% at a thiobencarb concentration of 1.26 mg/L. Growth and photosystem II activity (Fv/Fmratio) were drastically decreased at 5 mg/L, at which the expression levels of 13 proteins increased significantly and those of 11 proteins decreased significantly. Among these proteins, the level of the Rieske iron‐sulfur protein was decreased to less than half of the control level. This protein is an essential component of the cytochromeb6fcomplex in the photosynthetic electron transport chain. Although the mechanism by which thiobencarb decreased the Rieske iron‐sulfur protein level is not clear, these results suggest that growth was inhibited by interruption of the photosynthetic electron transport chain by thiobencarb. © 2013 Wiley Periodicals, Inc.
