The Roanoke logperch (Percina rex Jordan and Evermann), an endangered fish, occurs in only six watersheds in the Roanoke and Chowan river drainages of Virginia, USA. The species' population genetic structure is poorly known. We developed 16 microsatellite markers that were reliably scorable and polymorphic P. rex. Markers were also screened in seven other darter species of the genus Percina. Most markers exhibited successful amplification and polymorphism in several species. These markers may therefore prove useful for population genetic studies in other darters, a diverse but highly imperiled group.
罗诺克岩鲈（Percina rex Jordan and Evermann）是一种濒危鱼类，仅分布于美国弗吉尼亚州罗诺克和肖万河流域的六个水系中。该物种的种群遗传结构知之甚少。我们开发了 16 个微卫星标记，这些标记在罗诺克岩鲈中可可靠地进行评分和多态性分析。这些标记也在其他 7 种溪红点鲑属鱼类中进行了筛选。大多数标记在几种鱼类中都表现出了成功的扩增和多态性。因此，这些标记可能对其他溪红点鲑属鱼类的种群遗传研究有用，该属鱼类种类繁多，但高度濒危。
