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-002470nas a2200301 4500008004100000245009300041210006900134260000800203300001400211490000700225520151100232653001801743653001501761653001901776653002601795653002201821653001401843653002201857653003001879653002501909653001101934653002301945653002701968100001501995700001502010700002002025856012302045 2007 eng d00a[Analysis of ITS sequences of some medicinal plants and their related species in Salvia]0 aAnalysis of ITS sequences of some medicinal plants and their rel cDec a1309–130 v423 aMolecular systematic techniques were applied to reveal the genetic diversity of medicinal plants and their related species in Salvia. The internal transcribed spacer (ITS) as well as 5.8S rDNA sequences of 27 samples of Salvia were amplified using PCR method and sequenced. Mega 3.1 was used to analyze the genetic diversity within genus. The complete sequences of ITS plus 5.8S rDNA are about 612-617 bp. A phylogenetic tree generated by Neighbor-Joining method partly supported the morphological classification within Salvia, but incompatible results were also obtained in the treatment of phylogenetic positions of some species such as Salvia trijuga, Salvia flava var. flava and Salvia flava var. megalentha. The ITS regions of present Salria species showed considerable variation between subgenera in contrast with the conservative 5.8S rDNA sequences. The native Salvia species might have a different origin from the foreign species. The phylogenetic positions of subgenera and sections inferred by ITS analysis were comparable with that of traditional classification, while the phylogeny within sections is still doubtful due to limited information in ITS sequence and need to be further proved by other evidence. ITS analysis in this study supports the rationality of using species from Drymosphace section as substitute drug resources of Dan shen, but also reveals significant genetic differences between high mountain Dan shen species such as Salvia przewalskii with traditional Dan shen origins.10aBase Sequence10aDNA: Plant10aDNA: Ribosomal10aDNA: Ribosomal Spacer10aGenetic Variation10aPhylogeny10aPlants: Medicinal10aPolymerase Chain Reaction10aRNA: Ribosomal: 5.8S10aSalvia10aSequence Alignment10aSequence Analysis: DNA1 aWang, Ying1 aLi, Da-hui1 aZhang, Ying-tao uhttps://lamiaceae.myspecies.info/content/analysis-its-sequences-some-medicinal-plants-and-their-related-species-salvia02996nas a2200361 4500008004100000245013100041210006900172260000800241300001400249490000800263520196600271653002002237653001702257653002102274653002402295653001702319653001902336653001302355653001502368653001202383653001302395653001402408653001402422653001402436653001502450653001102465653001402476653002402490653001302514100001902527700002302546856006502569 2007 eng d00aStaminal evolution in the genus Salvia (Lamiaceae): Molecular phylogenetic evidence for multiple origins of the staminal lever0 aStaminal evolution in the genus Salvia Lamiaceae Molecular phylo cJan a375–3910 v1003 aBackground and Aims The genus Salvia has traditionally included any member of the tribe Mentheae (Lamiaceae) with only two stamens and with each stamen expressing an elongate connective. The recent demonstration of the non-monophyly of the genus presents interesting implications for staminal evolution in the tribe Mentheae. In the context of a molecular phylogeny, the staminal morphology of the various lineages of Salvia and related genera is characterized and an evolutionary interpretation of staminal variation within the tribe Mentheae is presented.Methods Two molecular analyses are presented in order to investigate phylogenetic relationships in the tribe Mentheae and the genus Salvia. The first presents a tribal survey of the Mentheae and the second concentrates on Salvia and related genera. Schematic sketches are presented for the staminal morphology of each major lineage of Salvia and related genera.Key Results These analyses suggest an independent origin of the staminal elongate connective on at least three different occasions within the tribe Mentheae, each time with a distinct morphology. Each independent origin of the lever mechanism shows a similar progression of staminal change from slight elongation of the connective tissue separating two fertile thecae to abortion of the posterior thecae and fusion of adjacent posterior thecae.
