Allozymic polymorphisms were also used to analyze genetic relationships among Salvia species. A contradiction in the phylogenetic positions of species studied was detected when phylogenetic trees were constructed using cpDNA or nrDNA, i.e., S. isensis was a sister to the other species in phylogenetic trees generated from cpDNA, while S. japonica was a sister to the other species in the case of nrDNA. Genetic relationships between Salvia species estimated from allozymic polymorphisms did not contradict to the topology for nrDNA. Using the present results, the speciation process of S. isensis is discussed with regard to introgressive gene exchanges between related species.10aBase Sequence10aCell Nucleus10aDNA Primers10aDNA: Chloroplast10aJapan10aPhylogeny10aSalvia1 a1 aOkada, Hiroshi  uhttps://lamiaceae.myspecies.info/content/speciation-process-salvia-isensis-lamiaceae-species-endemic-serpentine-areas-ise-tokai-0
