Previous tribal classifications of Rhamnaceae have been based on fruit characters, resulting in the delimitation of large and otherwise heterogeneous groups. We evaluated the most recent classification with DNA sequences of two regions of the plastid genome, rbcL and trnL-F, from 42 genera of Rhamnaceae and representatives of the related families Elaeagnaceae, Barbeyaceae, Dirachmaceae, Urticac...

L'hépatique macaronésienne Riccia boumanii Dirkse, Losada & M.Stech (Marchantiophyta: Ricciaceae) confirmée nouvelle en Asie par des preuves morphologiques et moléculaires. L. est le plus grand genre d'hépatiques thalloïdes complexes avec de 250 espèces actuellement acceptées. (Ricciaceae) a été considérée comme endémique îles Canaries, Espagne. Des analyses phylogénétiques moléculaires basées ...

We present an analysis of relationships in Gilliesioideae (Alliaceae) based on a combined matrix of plastid rbcL, the trnL intron, the trnL-F intergenic spacer, and the rpsl6 intron and nuclear ITS ribosomal DNA sequences. The results are generally congruent with previous analyses, indicating two well-supported groups: Ipheion plus allied genera ("lpheieae" ined.) and Gilliesieae. They also pro...

In order to investigate interfamilial relationships of Liliales we analyzed a combined matrix of plastid rbcL, trnL intron, trnL-F intergenic spacer, rnatK, and ndhF, and mitochondrial atpl DNA sequences. The results are generally congruent with previous broad analyses and provide higher bootstrap support for many relationships. Important changes relative to previous studies are the recognition...

Cytoplasmic chloroplast DNA was explored to establish genetic relationships among Ficus carica cultivars and elucidate the molecular evolution of the species. The results suggest the occurrence of haplotype and nucleotide diversity. Conserved group I intron sequence motifs were detected and showed a common secondary structure, despite the presence of some mutations on their sequences. The neigh...

In order to compare the efficiency of morphological traits and molecular markers in distinguishing the Consolida species, molecular analysis using nrDNA ITS and cpDNA trnL-trnF with maximum parsimony and Bayesian methods were done in a total of 34 species and forma representing 28 species of Consolida, 6 species of Aconitella, plus two species of Delphinium and two species of Aconitum as out gr...
