摘要To clarify the relationship between two genera Draba and the narrow genus Coelonema endemic to the QilianMountains of the northeastern Qinghai-Tibet Plateau phylogenetic analyses were conducted using nuclear ribosomal DNA ITS and the chloroplast DNA trnL from Coelonema draboides and 30 species of Draba representing eight sections including 25 species of Chinese Draba seven of which were endemic to the study region The results unambiguously support several previously published proposals to unite Coelonema with Draba and accommodate C draboides in the latter genus on the basis of morphological re-examination Our molecular data presented here also provide evidence that these two genera should be combined as a monophyletic group with high support In addition it is estimated that Draba may have originated about 1 36-2 71 Mya with C draboides diverging from Draba about 0 15-0 31 Mya based on the molecular calibration of ITS datasets The assumed speciation and rapid expansion of these two genera is likely to have occurred in the eastern edge of the QilianMountains area according to molecular phylogeny and estimated divergence times which correspond well with the known geological and paleobotanical histories of the Qinghai-Tibet Plateau (C) 2010 Elsevier Ltd All rights reserved; To clarify the relationship between two genera Draba and the narrow genus Coelonema endemic to the QilianMountains of the northeastern Qinghai-Tibet Plateau phylogenetic analyses were conducted using nuclear ribosomal DNA ITS and the chloroplast DNA trnL from Coelonema draboides and 30 species of Draba representing eight sections including 25 species of Chinese Draba seven of which were endemic to the study region The results unambiguously support several previously published proposals to unite Coelonema with Draba and accommodate C draboides in the latter genus on the basis of morphological re-examination Our molecular data presented here also provide evidence that these two genera should be combined as a monophyletic group with high support In addition it is estimated that Draba may have originated about 1 36-2 71 Mya with C draboides diverging from Draba about 0 15-0 31 Mya based on the molecular calibration of ITS datasets The assumed speciation and rapid expansion of these two genera is likely to have occurred in the eastern edge of the QilianMountains area according to molecular phylogeny and estimated divergence times which correspond well with the known geological and paleobotanical histories of the Qinghai-Tibet Plateau (C) 2010 Elsevier Ltd All rights reserved
