(Lamioideae: Lamiaceae) inferred from nuclear and chloroplast sequence datasets0 aOrigin of Macaronesian Sideritis L Lamioideae Lamiaceae inferred  cJun  a293–3060 v233 aSideritis L. (Lamiaceae) comprises approximately 150 species of annuals and perennials distributed chiefly in the Mediterranean region. The majority of the species belong to the continental subgenus Sideritis which is divided into two perennial (Sideritis and Empedoclea) and two annual (Hesiodia and Burgsdorfia) sections. Twenty-three species are woody perennials endemic to the Macaronesian archipelagos of Madeira and the Canary Islands. In an effort to determine the continental origin of the insular group, we constructed independent phylogenies comprising sequence data from both chloroplast and nuclear markers. Sampling included 7 island taxa drawn from the Macaronesian subgenus Marrubiastrum and 25 continental taxa representing all four sections of subgenus Sideritis. Subgenus Marrubiastrum and the two continental perennial sections form well-supported monophyletic groups in both individual and combined analyses. The annual sections are not monophyletic in any analysis; further sampling of annual taxa is needed to resolve these relationships. All analyses identified Sideritis cossoniana, an annual species from Morocco, as the closest continental relative of the Macaronesian group. This contrasts with the hypothesis of earlier workers who suggested that the insular taxa were most closely related to eastern Mediterranean species of the genus. The phylogenies also demonstrate a distinct increase in woodiness among the Macaronesian species relative to their continental congeners, providing further support for the secondary nature of woodiness in island plants.10aBiological Evolution10aCell Nucleus10aChloroplasts10aDNA: Intergenic10aDNA: Ribosomal10aGenetic Variation10aIntrons10aPhylogeny10aPortugal10aSideritis10aSpain1 aBarber, Janet, C1 aFrancisco-Ortega, Javier1 aSantos-Guerra, Arnoldo1 aTurner, Kathryn, G1 aJansen, Robert, K  uhttp://linkinghub.elsevier.com/retrieve/pii/S1055-7903(02)00018-002986nas a2200385   4500008004100000245010400041210006900145260000800214300001300222490000700235520180100242653001802043653002502061653001502086653002002101653001502121653001202136653001402148653002802162653002102190653001402211653001302225653001102238100001902249700002102268700001902289700001902308700002202327700002402349700001802373700002702391700002202418700002402440856013602464       2004                        eng d00aPhylogeny and evolution of basils and allies (Ocimeae, Labiatae) based on three plastid DNA regions0 aPhylogeny and evolution of basils and allies Ocimeae Labiatae ba  cApr  a277–990 v313 aA phylogeny of basils and allies (Lamiaceae, tribe Ocimeae) based on sequences of the trnL intron, trnL-trnF intergene spacer and rps 16 intron of the plastid genome is presented. Several methods were used to reconstruct phylogenies and to assess statistical support for clades: maximum parsimony with equally and successively weighted characters, bootstrap resampling, and Bayesian inference. The phylogeny is used to investigate the distribution of morphological, pericarp anatomy, chemical, and pollen characters as well as the geographical distribution of the clades. Tribe Ocimeae is monophyletic and easily diagnosable with morphological synapomorphies. There are monophyletic clades within Ocimeae that broadly correspond to currently recognised subtribes: Lavandulinae, Hyptidinae, Ociminae, and Plectranthinae. Only Lavandulinae has clear non-molecular synapomorphies. Several currently recognised genera are not monophyletic. Floral morphology consistent with sternotribic pollination is most common in Ocimeae, but there are independent departures from this model. Buzz pollination is likely in some species, the only postulated occurrence of this within Lamiaceae. Quinone diterpenoids and flavones in the leaf exudates differ in their distributions across the phylogeny and this could contribute to differences in the recorded medicinal as well as pesticidal uses of the species in the different clades. Mapping geographic distribution on to an ultrametric phylogenetic tree produced using non-parametric rate smoothing supports an Asiatic origin for Ocimeae. There are several secondary occurrences in Asia arising from the African Ociminae and Plectranthinae clades. Colonisation of Madagascar occurred at least five times, and New World colonisation occurred at least three times.10aBayes Theorem10aBiological Evolution10aDiterpenes10aDNA: Intergenic10aFlavonoids10aIntrons10aLamiaceae10aMolecular Sequence Data10aOcimum basilicum10aPhylogeny10aPlastids10aPollen1 aPaton, Alan, J1 aSpringate, David1 aSuddee, Somran1 aOtieno, Donald1 aGrayer, Renée, J1 aHarley, Madeline, M1 aWillis, Fiona1 aSimmonds, Monique, S J1 aPowell, Martyn, P1 aSavolainen, Vincent  uhttps://lamiaceae.myspecies.info/content/phylogeny-and-evolution-basils-and-allies-ocimeae-labiatae-based-three-plastid-dna-regions
