使用来自六个核（18S、gbssil、gbssi2、ITS、pgip 和 ppo）和四个叶绿体（matK、ndhF、rbcL 和 trnL-trnF）区域的核苷酸序列数据，分别或以各种组合，采用基于简约和似然的贝叶斯方法，研究了 88 个蔷薇科属之间的系统发育关系。结果用于检查非分子特征的进化，并开发一种新的基于系统发育的科下分类。与之前对该科的分子系统发育分析一样，我们发现对与许多先前认识的部落和亚科密切对应的群体单系性的强烈支持，但先前的分类没有得到完全支持，并且强烈支持的进化枝之间的关系在某些数据集之间解析不力和/或存在冲突。我们认识到蔷薇科的三个亚科： Rosoideae，包括 Filipendula、Rubus' Rosa 和三个族； Dryadoideae，包括四个放线菌属；和绣线菊科，包括 Lyonothamnus 和七个部落。之前归属于 Amygdaloideae 和 Maloideae 的所有属都包含在 Spiraeoideae 中。已识别出三个超级部落，一个属于蔷薇亚科，两个属于绣线菊亚科。
Phylogenetic relationships among 88 genera of Rosaceae were investigated using nucleotide sequence data from six nuclear (18S, gbssil, gbssi2, ITS, pgip, and ppo) and four chloroplast (matK, ndhF, rbcL, and trnL-trnF) regions, separately and in various combinations, with parsimony and likelihood-based Bayesian approaches. The results were used to examine evolution of non-molecular characters and to develop a new phylo-genetically based infrafamilial classification. As in previous molecular phylogenetic analyses of the family, we found strong support for monophyly of groups corresponding closely to many previously recognized tribes and subfamilies, but no previous classification was entirely supported, and relationships among the strongly supported clades were weakly resolved and/or conflicted between some data sets. We recognize three subfamilies in Rosaceae: Rosoideae, including Filipendula, Rubus' Rosa, and three tribes; Dryadoideae, comprising the four actinorhizal genera; and Spiraeoideae, comprising Lyonothamnus and seven tribes. All genera previously assigned to Amygdaloideae and Maloideae are included in Spiraeoideae. Three supertribes, one in Rosoideae and two in Spiraeoideae, are recognized.
