	abstract = {OBJECTIVE: To analyze the nuclear ribosome DNA (nrDNA) internal transcribed spacer (ITS) sequences of 4 Leonurus species, and the possibility of using them for molecular authentication of the crude drugs from the genus. METHODS: The nrDNA ITS sequence (including ITS1, 5.8S rDNA, ITS2, and partial 18S rDNA and 26S rDNA) of L. japonicus and its 3 adulterant species were amplified and sequenced, and CLUSTRAL X and MEGA software was employed for analysis. RESULTS: The variation of ITS1 and ITS2 between L. japonicus and its adulterant species ranged between 7.2\% and 18.8\% and between 14.2\% and 27\%, respectively. The phylogenic tree derived from the dendrograms based on the ITS sequence data contained some discrepancy from the traditional classification. CONCLUSION: The nrDNA ITS sequences can be used potentially as efficient markers for identification of L. japonicus and its adulterants, and further study is needed for studying the phylogeny of Leonurus.},

	abstract = {The Canary Islands have been a focus for phylogeographic studies on the colonization and diversification of endemic angiosperm taxa. Based on phylogeographic patterns, both inter island colonization and adaptive radiation seem to be the driving forces for speciation in most taxa. Here, we investigated the diversification of Micromeria on the Canary Islands and Madeira at the inter- and infraspecific level using inter simple sequence repeat PCR (ISSR), the trnK-Intron and the trnT-trnL-spacer of the cpDNA and a low copy nuclear gene. The genus Micromeria (Lamiaceae, Mentheae) includes 16 species and 13 subspecies in Macaronesia. Most taxa are restricted endemics, or grow in similar ecological conditions on two islands. An exception is M. varia, a widespread species inhabits the lowland scrub on each island of the archipelago and could represent an ancestral taxon from which radiation started on the different islands. Our analyses support a split between the "eastern" islands Fuerteventura, Lanzarote and Gran Canaria and the "western" islands Tenerife, La Palma and El Hierro. The colonization of Madeira started from the western Islands, probably from Tenerife as indicated by the sequence data. We identified two lineages of Micromeria on Gomera but all other islands appear to be colonized by a single lineage, supporting adaptive radiation as the major evolutionary force for the diversification of Micromeria. We also discuss the possible role of gene flow between lineages of different Micromeria species on one island after multiple colonizations.},
