DNA sequences of red algal corallines, offshore northwest Gulf of Mexico, 2011-2012

A phylogenetic analysis of concatenated plastid (psbA) and nuclear (LSU rDNA) DNA sequences of non-geniculate corallines belonging to the subfamily Lithophylloideae (Corallinaceae), including newly generated sequences from recently collected specimens dredged at Ewing and Sackett Banks following the April 2010 Deepwater Horizon oil spill, reveals at least two distinct species of Lithophyllum sensu lato for the region.

针对隶属于珊瑚藻科（Corallinaceae）石叶藻亚科（Lithophylloideae）的无关节珊瑚藻，本研究对其拼接的质体psbA序列与核大亚基核糖体DNA（LSU rDNA）序列开展系统发育分析；分析样本包含2010年4月深水地平线（Deepwater Horizon）漏油事件后，在尤因与萨克特浅滩（Ewing and Sackett Banks）拖网采集的新近标本所生成的全新序列，结果显示该区域至少存在两种广义石叶藻属（Lithophyllum sensu lato）的独立物种。
