应用SuperTRI方法重建百合目的系统发育关系

Using SuperTRI Methods to Reconstruct the Phylogenetic Relationships of Liliales

  • 摘要: SuperTRI是Ropiquet等(2009)发表的一种新的超树方法,可以通过合并所有系统发育信息来共同组建大的系统发育树。该方法克服了超矩阵法和传统超树法的一些限制,使提出的系统发育假说可信度更高,更具有统计说服力。本文应用SupperTRI方法重建了百合目(Liliales)主要类群的系统发育关系,并与超矩阵法的分析结果进行了比较。结果显示:(1)SuperTRI方法产生了与超矩阵法相似的拓扑结构,但节点支持率相对较低,其中再现性指数对评判分支的可信性更容易理解,在系统树图示方法上也更直观;(2)SuperTRI系统树证实百合科、菝葜科、垂花科和菝葜藤科为一单系分支;黑药花科为一独立分支;秋水仙科、六出花科、刺藤科为一单系分支,但这3个大分支间的关系未明;支持白玉簪科和金梅草科互为姐妹群,是百合目最基部类群。

     

    Abstract: Ropiquet et al.(2009) proposed a new approach called SuperTRI (SuperTree with Reliability Indices) to combine all phylogenetic information available for the construction of large,synthetic phylogenetic trees.This approach overcomes some limitations of Supermatrix analysis and Supertree analysis,and allows larger scale hypotheses to be more reliable and with stronger statistical power.In this paper,we applied SuperTRI to construct a liliales phylogenetic tree.Compared to those found with the supermatrix approach,the results indicated: (1) the topology of SuperTRI tree is similar to those of the Supermatrix tree,but gives lower branch support values relatively,where reproducibility index for judging node reliability is the easiest way to understand and also the most intuitive method shown by the phylogenetic tree; (2) our results confirmed that Liliaceae,Smilaceae,Philesiaceae and Ripogonaceae are one monophyletic clade,Melanthiaceae is another monophyletic clade,and Colchicaceae,Alstroemeriaceae and Petermanniaceae are another.However,the phylogenetic relationship between the three clades remains uncertain.Corsiaceae and Campynemataceae are a sister group and the first branch in the order.
