Recently, sequences from two nuclear genes (exon 6 of the dentin matrix protein 1 gene and intron 7 of the beta-fibrinogen gene) and one mitochondrial gene (cytochrome b gene) were used independently in an attempt to resolve phylogenetic relationships within the neotomine-peromyscine complex. Although these studies provided testable hypotheses regarding this group of rodents, the affinities of certain tribes and genera remain uncertain. To elucidate these relationships, the three data partitions were tested for heterogeneity and then concatenated according to conditional data combination and total evidence approaches. Support was found for five clades, four of which correspond to well recognized tribes (the Neotomini, Peromyscini=Reithrodontomyini, Baiomyini, and Tylomyini). Recommendations are made regarding the recognition of Ochrotomys as a tribe of its own, the Ochrotomyini, paralleling other recent findings. The Peromyscini, Baiomyini, and Ochrotomyini are unresolved in relation to each other, but as a whole are sister to the Neotomini. The Tylomyini is basal to all clades. It appears that combined data from the nuclear and mitochondrial genes (analyzing all three partitions simultaneously) resulted in the best phylogenetic hypothesis regarding the complex.
最近，来自两个核基因（牙本质基质蛋白1基因的外显子6和β-纤维蛋白原基因的内含子7）和一个线粒体基因（细胞色素b基因）的序列被单独用于试图解析新鼠属-鹿鼠属复合体内部的系统发育关系。尽管这些研究提供了关于这组啮齿动物的可检验假设，但某些族和属的亲缘关系仍不确定。为了阐明这些关系，对这三个数据分区进行了异质性检验，然后根据条件数据组合和总证据方法进行串联。发现了五个分支得到支持，其中四个对应于公认的族（新鼠族、鹿鼠族=白足鼠族、白耳鼠族和棉鼠族）。根据与其他近期研究结果相似的情况，建议将赭鼠属识别为一个独立的族，即赭鼠族。鹿鼠族、白耳鼠族和赭鼠族之间的关系尚未确定，但总体上是新鼠族的姐妹分支。棉鼠族是所有分支的基部。看来，来自核基因和线粒体基因的组合数据（同时分析所有三个分区）产生了关于该复合体的最佳系统发育假设。
