摘要

摘要报道了北美西南部荒漠土壤中一新种(Tetradesmus adusstus)。该鉴定是基于核(ITS2 rDNA)和质体(rbcL, tufA)条形码标记的系统发育分析。这个新描述的物种代表了场景科中适应干旱的藻类的第五个隐种。在我们新获得的数据背景下，对已发表的沙漠四足鼠序列进行了重新分析，重申了强大的系统发育分析在鉴定隐秘分类群(如四足鼠物种)中的重要性。

A new species of Tetradesmus (Chlorophyceae, Chlorophyta) isolated from desert soil crust habitats in southwestern North America

Abstract A new species of Tetradesmus (Tetradesmus adustus) is described from desert soils of southwestern North America. The identification is based on phylogenetic analysis of data from nuclear (ITS2 rDNA) and plastid (rbcL, tufA) barcode markers. This newly described species represents the fifth cryptic species of arid-adapted algae in Scenedesmaceae. A re-analysis of published sequences attributed to desert Tetradesmus in the context of our newly obtained data reiterates the importance of robust phylogenetic analysis in identification of cryptic taxa, such as species of Tetradesmus.
