Abstract

The region between the rbcL and atpB chloroplast genes and the first 53 codons of the rbcL gene have been sequenced for 19 species of angiosperms. Nine of these belong to the four largest families within the order Celastrales sensu Cronquist (i.e., Aquifoliaceae s.l., Icacinaceae, Celastraceae, and Hippocrateaceae). Both phenetic and cladistic approaches were used to test the monophyly of the order and to specify its relationships with Euphorbiaceae, Rhamnaceae, Rosaceae, and Theaceaea. Based upon this molecular analysis, the order Celastrales is polyphyletic and is divided into two major clades. The first group, containing Aquifoliaceae s.l. and Icacina, is related to Camellia (Theaceae). The second, containing Euonymus (Celastraceae), Hippocratea, and Salacia (Hippocrateaceae), is related to Euphorbia (Euphorbiaceae).

摘要

已对19种被子植物的叶绿体基因rbcL和atpB之间的区域以及rbcL基因的前53个密码子进行了测序。其中9种属于克朗奎斯特分类系统中Celastrales目内的四个最大科（即广义冬青科、茶茱萸科、卫矛科和翅子藤科）。运用表型分类法和分支分类法来检验该目的单系性，并明确其与大戟科、鼠李科、蔷薇科和山茶科的关系。基于这一分子分析，Celastrales目是多系的，可分为两个主要分支。第一组包含广义冬青科和茶茱萸科，与山茶属（山茶科）相关。第二组包含卫矛属（卫矛科）、翅子藤属和五层龙属（翅子藤科），与大戟属（大戟科）相关。
