| 摘 要： | 斑果藤族(Stixeae)和节蒴木属(Borthwickia)传统上被置于山柑科(Capparaceae),最近的分子和形态学证据均支持它们从山柑科中分离出来,节蒴木属已被提升为科,但斑果藤族的系统位置和分类地位尚不清楚。为解决斑果藤族的系统位置和分类地位,并进一步为节蒴木科的成立提供证据,对核心十字花目GRFT(Gyrostemonaceae-ResedaceaeForchhammeria-Tirania)分支,使用叶表皮等20个形态性状和5个DNA片段(mat K、rbc L、ndh F、trn L-F和ITS),用最大简约法(MP)和贝叶斯分析(BI)对形态及分子矩阵进行系统发育分析。结果高度支持斑果藤族的Neothorelia为GRFT分支成员;Neothorelia、Tirania和斑果藤属(Stixis)聚为一支,但Forchhammeria的位置尚不明确;形态及分子系统发育分析结果均支持节蒴木科成立。 |

| Abstract: | Stixeae (including Stixis, Tirania, Neothorelia and Forchhammeria) and Borthwickia have traditionally been placed in Capparaceae. Recent molecular and morphological studies suggest Borthwickia as a new monotypic family. However, the positions and taxonomic ranks of Stixeae remain unresolved. To estimate the relationships of Stixeae, we reconstructed the phylogeny of the Gyrostemonaceae-Resedaceae-Forchhammeria-Tirania (GRFT) clade of the core Brassicales using maximum parsimony and Bayesian analysis with 20 morphological characters and five DNA regions (matK, rbcL, ndhF, trnL-F, and ITS). Our results strongly support Neothorelia as a new member of the GRFT clade; Neothorelia, Tirania and Stixis form a clade with strong support. The systematic position of Forchhammeria is still uncertain; molecular and morphological evidence support Borthwickiaceae as a new monotypic family. |
