Brown algae, diatoms and xanthophyceae are main constituents of stramenopile algae. Stramenopile algae are the main primary producers in ocean. From a stramenopile alga, Vaucheria (Xanthophyceae), we discovered the novel blue light receptor aureochrome. Aureochrome was found to be a new type of bZIP-LOV protein, and was found to be a blue light-activated transcription factor. It probably mediates the blue-light-induced branching and regulates the sexual development in Vaucheria. Aureochromes are common and specific to stramenopile algae, but not existed in green plants. Function of aureochromes in other stramenopile algae is not known to date.

褐藻、硅藻和黄藻是原生藻藻的主要成分。原生藻藻是海洋中主要的初级生产者。我们从原生藻藻 Vaucheria（黄藻纲）中发现了新型蓝光受体金色素。 Aureochrome被发现是一种新型的bZIP-LOV蛋白，并且被发现是蓝光激活的转录因子。它可能介导蓝光诱导的分支并调节 Vaucheria 的性发育。金色素是原生藻菌所特有的常见物质，但在绿色植物中并不存在。迄今为止，金色素在其他原生藻藻中的功能尚不清楚。
