摘要

Green algae, in surface layers of almost every lake or stream, are some of the most common aquatic creatures. However, unbeknownst to researchers until recently, viruses that infect algae are almost as widespread. Entire ecosystems of algal hosts and their corresponding viruses lay hidden until the 1980s, when James L. Van Etten, a professor of plant pathology at the University of Nebraska (Lincoln), and his colleague Russ Meints discovered and began to characterize the first member of what is now a rapidly expanding family of algal viruses. Van Etten and his colleagues have continued to study these intriguing viruses, focusing on those that infect Chlorella and other similar green algae. The chlorella viruses have many unusual properties, ranging from their large genome sizes to unique modifications in their DNA. Van Etten's findings have earned him continuous grant support from the National Institutes of Health as well as election to fellow status in several professional societies. In 2003, he was elected to the National Academy of Sciences. His Inaugural Article, found on page 5318 (1), explores the electro-physiological properties of a unique potassium ion channel protein encoded by the chlorella viruses. The small size of this protein could make it a useful model for studying how more complex potassium ion channels work.

Van Etten和他的同事Russ Meints发现并开始刻画藻类的第一个成员现在是快速扩展的藻类病毒家族。范·埃滕（Van Etten）和他的同事们继续研究这些有趣的病毒，重点研究感染小球藻和其他类似绿藻的病毒。小球藻病毒具有许多不同寻常的特性，从其较大的基因组大小到其DNA的独特修饰。范·埃滕（Van Etten）的发现为他赢得了美国国立卫生研究院（National Institutes of Health）的持续拨款支持，并在几个专业学会中获选为同胞身份。 2003年，他当选为美国国家科学院院士。他的就职论文位于第5318页（1），探讨了由小球藻病毒编码的独特钾离子通道蛋白的电生理特性。这种蛋白质的小尺寸使其成为研究更复杂的钾离子通道如何起作用的有用模型。
