最近的分子系统学分析支持了山茱萸目、杜鹃花科和核心植物之间关系的不同假设。这些假设对植物重要的形态学和胚胎学特征的进化有一定的意义。（Cornales）和Franklinia（杜鹃花科），并将它们与已发表的真双子叶植物序列数据相结合，我们的最大简约，最大似然，和贝叶斯分析产生强有力的支持和一致的系统发育关系之间的三个主要谱系的马唐Cornales分歧首先在马唐，欧石楠目是核心植物的姐妹植物。在简约性分析中，增加两个分类群有助于减轻长分支吸引力。编码基因可能为真双子叶植物包括双子叶植物的基底谱系的关系提供满意的解析和支持
Recent phylogenetic analyses of molecular data have supported different hypotheses of relationships among Cornales, Ericales, and core asterids Such hypotheses have implications for the evolution of important morphological and embryological features of asterids In this study we generated plastid genome-scale data of Davidia (Cornales) and Franklinia (Ericales) and combined them with published sequence data of eudicots Our maximum parsimony, maximum likelihood, and Bayesian analyses generated strongly supported and congruent phylogenetic relationships among the three major lineages of the asterids Cornales diverges first in asterids, Ericales is sister to the core asterids Adding two more taxa helps mitigate long branch attraction in parsimony analyses Sampling 26-28 plastid protein-coding genes may provide satisfactory resolution and support for relationships of eudicots including basal lineages of asterids
