A new metagenomics study has shown that marine viruses recently acquired genes encoding light-gated ion channels from green algae. These so-called channelrhodopsin genes may allow the viruses to manipulate the swimming behavior of the algae they infect.

进化生物学：病毒视紫红质阐明藻类进化

一项新的宏基因组学研究表明，海洋病毒最近从绿藻中获得了编码光门控离子通道的基因。这些所谓的通道视紫红质基因可以使病毒操纵它们感染的藻类的游动行为。
