Phylogeny of the genus Apodemus with a special emphasis on the subgenus Sylvaemus using the nuclear IRBP gene and two mitochondrial markers: cytochrome b and 12S rRNA

摘要: Phylogenetic relationships among 17 extant species of Murinae, with special reference to the genus Apodemus, were investigated using sequence data from nuclear protein-coding gene IRBP (15 species) and two mitochondrial genes cytochrome b 12S rRNA (17 species). The analysis three does not resolve between Mus, Rattus but separates Micromys these genera. regions supported an association Apodemus Tokudaia indicated that genera are more closely related Mus than or Micromys. Within sets 8 9 analyzed can be sorted into main groups: group, A. agrarius, semotus, peninsulae, a Sylvaemus uralensis, flavicollis, alpicola, sylvaticus, hermonensis. position mystacinus is ambiguous might either included in considered distinct subgenus, Karstomys, Apodemus. Estimation divergence time for taxa suggests separation 7 My ago groups (mystacinus subgenera Sylvaemus). each times 5.4 6 2.2 3.5 mystacinus.
