对蔷薇亚科44种植物的生殖系统进行了研究。在这里，我们报告的叶绿体trnL/F区的新的序列数据，以及增加的样品的物种。这些新数据的分析，沿着与以前使用的核核糖体内转录间隔区（ITS）的数据，显着提高分辨率以及信心蔷薇亚科的单倍型。使用贝叶斯推理和简约方法，我们进行了分析的数据集单独和组合。由此产生的cumbergenies是一致的所有良好的支持分支Rosoideae发现在以前的ITS或rbcL数据分析。这些和其他分支的支持得到了改善，我们认为有几个分支得到了足够好的支持，可以命名。以下分支给出了系统发育定义：地榆亚科及其亚科龙芽草亚科和地榆亚科，委陵菜亚科及其亚科草莓亚科和委陵菜属，罗盖菜属（蔷薇属+地榆亚科+委陵菜亚科）和桑卜蒂娜属（地榆亚科+委陵菜亚科）。委陵菜包括蕨麻的分支（阿根廷）在我们的trnL/F和合并分析，但这种关系是不是单独解决ITS。以前使用的属Duchesnea（委陵菜），Horkelia和Ivesia强烈支持嵌套在委陵菜内。Comarum（Potentila palustris和Potentila salesowianum），Sibbaldiopsis（Potentila tridentata），Dasiphora（Potentila fruticosa）和Drymocallis（Potentila plutta）加入了Alchemilla，Apanes，Sibbaldia，Chamaerhodos和Fragaria在Potentila之外的Fragariinae分支中。Potentillae和Sanguisorbeae的单系性得到了很好的支持，并且分支对应于以前命名的部落，除了Alchemilla和它的分离Aphanes，它们嵌套在Potentillae而不是Sanguisorbeae中。悬钩子的位置仍然没有得到安全解决。
The phylogeny of Rosoideae was investigated using 44 species. Here we report new sequence data from the chloroplast trnL/F region as well as an increased sample of species. The analysis of these new data, along with previously used data from the nuclear ribosomal internal transcribed spacers (ITS), significantly increased resolution as well as confidence for Rosoideae phylogeny. Using both Bayesian inference and parsimony methods, we conducted analyses on the data sets separately and in combination. The resulting phylogenies are congruent with all well-supported clades of Rosoideae found in previous analyses of ITS or rbcL data. The support for these and other clades is improved, and we consider several clades to be supported well enough to be named. The following clades are given phylogenetic definitions: Sanguisorbeae and its subclades Agrimoniinae and Sanguisorbinae, Potentilleae and its subclades Fragariinae and Potentilla, Roperculina (Rosa + Sanguisorbeae + Potentilleae), and Sanpotina (Sanguisorbeae + Potentilleae). Potentilla includes the Potentilla anserina clade (Argentina) in our trnL/F and combined analyses, but this relationship is not resolved by ITS alone. The previously used genera Duchesnea (Potentilla indica), Horkelia, and Ivesia are strongly supported as nested within Potentilla. Comarum (Potentilla palustris and Potentilla salesowianum), Sibbaldiopsis (Potentilla tridentata), Dasiphora (Potentilla fruticosa), and Drymocallis (Potentilla arguta) join Alchemilla, Aphanes, Sibbaldia, Chamaerhodos, and Fragaria in the well-supported Fragariinae clade outside of Potentilla. The monophyly of both Potentilleae and Sanguisorbeae is well supported, and the clades correspond to previously named tribes with the exception of Alchemilla and its segregate Aphanes, which are nested within Potentilleae instead of in Sanguisorbeae. The position of Rubus is still not securely resolved.
