(Lamiaceae): Disentangling origins of presumed allotetraploids0 aMolecular phylogeny and taxonomy of the genus Lamium L Lamiaceae  cJan  a986–10000 v603 aThis is the first comprehensive molecular investigation of the genus Lamium L. We have addressed phylogenetic relationships and presumed allopolyploid speciation by use of nuclear (NRPA2, 5S-NTS) and chloroplast (matK, psbA-trnH, rps16, trnL, trnL-F, trnS-G) DNA sequence data. Nuclear and chloroplast data were incongruent, and nuclear data showed better correlation with morphology. Bayesian and parsimony phylogenetic results show that (I) Lamium galeobdolon is sister to all remaining Lamium species; (2) Wiedemannia is nested within Lamium; (3) L. amplexicaule is polyphyletic; (4) most tetraploids are of hybrid origin; (5) L. amplexicaule var. orientale is allotetraploid; and (6) Mennema's (1989) infrageneric classification is not corroborated by molecular data. Based on the molecular results, and taking morphology into account, we suggest resurrection of two species: L. aleppicum and L. paczoskianum.10a5S-Nts10aAllopolyploidy10aAsteraceae10aChloroplast Dna10aClassification10aComplex10aCpdna10aDna-Sequences10aIncongruence10aLamioideae10aLamium10aMolecular Phylogenetics10aNrpa210aReconstruction10aReticulate Evolution10aSilene Caryophyllaceae10aSpeciation1 aBendiksby, Mika1 aBrysting, Anne, K1 aThorbek, Lisbeth1 aGussarova, Galina1 aRyding, Olof  uhttp://apps.webofknowledge.com/InboundService.do?SID=2B%2540kNem2NICHnHfl3PI&product=WOS&UT=000294507000004&SrcApp=Papers&DestFail=http%253A%252F%252Faccess.isiproducts.com%252Fcustom_images%252Fwok5_failed_auth.html&Init=Yes&action=retrieve&SrcAuth=meken03006nas a2200277   4500008004100000245014900041210006900190260000800259300001400267490000700281520191100288653002702199653002002226653001702246653002702263653002302290653002202313653002202335653002602357653002502383653001402408100001602422700001502438700001502453856026002468       2006                        eng d00aMolecular phylogeny of Conradina and other scrub mints (Lamiaceae) from the southeastern USA: Evidence for hybridization in Pleistocene refugia?0 aMolecular phylogeny of Conradina and other scrub mints Lamiaceae  cJan  a193–2070 v313 aConradina (Lamiaceae) consists of six allopatric species endemic to the southeastern United States, four of which are federally endangered or threatened. The limits and status of several taxa have been contested based on morphological grounds, and clarification of these limits is necessary for the design and implementation of effective and fiscally responsible protection and management plans. The objectives of this study were to investigate the monophyly of Conradina and its relationship to other endemic mints of the southeastern United States, to understand the patterns of diversification in Conradina, and to clarify species relationships. A molecular phylogeny was inferred by sequencing ITS and plastid regions from multiple accessions of each species of Conradina (except for a single accession of C. verticillata) and multiple individuals from species of Clinopodium, Dicerandra, Piloblephis, Stachydeoma, Monarda, Pycnanthemum, and Mentha. ITS sequence data strongly support the monophyly of Conradina, in agreement with evidence from morphology. In contrast, plastid sequence data do not support a monophyletic Conradina and place the genus as paraphyletic to Clinopodium, Stachydeoma, and Piloblephis. Similar plastid haplotypes are shared by different genera, perhaps due to shared ancestral polymorphisms, or more likely, introgression that occurred recently or during the Pleistocene. Within Conradina, ITS sequence data do not resolve species relationships, while plastid sequence data do not support the monophyly of most traditionally defined species of Conradina that are distinguishable morphologically. Species relationships in the plastid data set may also be obscured by introgression or ancestral polymorphism. More rapidly evolving sequence data from nuclear markers will be necessary to clarify relationships in Conradina and related mints from the southeastern United States.10aArmeria Plumbaginaceae10aChloroplast Dna10aIncongruence10aLength Difference Test10aMaximum-Likelihood10aMitochondrial-Dna10aNoncoding Regions10aNuclear Ribosomal Dna10aReticulate Evolution10aSequences1 aEdwards, CE1 aSoltis, DE1 aSoltis, PS  uhttp://apps.isiknowledge.com/InboundService.do?product=WOS&action=retrieve&SrcApp=Papers&UT=000236119500018&SID=2AFL5dnj5MCc8JPedL5&SrcAuth=mekentosj&mode=FullRecord&customersID=mekentosj&DestFail=http%253A%252F%252Faccess.isiproducts.com%252Fcustom_image
