The internal transcribed spacers (ITS) of the nuclear ribosomal DNA and trnL-F region of the chloroplast DNA were sequenced for all ten species of Chloranthus and the outgroup Sarcandra (Chloranthaceae). Parsimony analyses of separate and combined data sets strongly suggest that Chloranthus is monophyletic and can be divided into two major clades: one containing C. erectus, C. spicatus, C. serr...

The genus Crinum L. is the only pantropical genus of the Amaryllidaceae. Phylogenetic and biogeographical analyses of nrDNA ITS and plastid trnL-F sequences for all continental groups of the genus Crinum and related African genera are presented, with the genus Amaryllis used as outgroup. ITS indicates that C. baumii is more closely related to Ammocharis and Cybistetes than to Crinum sensu stric...

BACKGROUND AND AIMS The phylogenetic relationships between species of Coffea and Psilanthus remain poorly understood, owing to low levels of sequence variation recovered in previous studies, coupled with relatively limited species sampling. In this study, the relationships between Coffea and Psilanthus species are assessed based on substantially increased molecular sequence data and greatly imp...

UNLABELLED Mango (>Mangifera indica) belonging to Anacardiaceae family is a fruit that grows in tropical regions. It is considered as the King of fruits. The present work was taken up to identify a tool in identifying the mango species at the molecular level. The chloroplast trnL-F region was amplified from extracted total genomic DNA using the polymerase chain reaction (PCR) and sequenced. Seq...

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...

The group I intron interrupting the tRNALeu UAA gene (trnL) is present in most cyanobacterial genomes as well as in the plastids of many eukaryotic algae and all green plants. In lichen symbiotic Nostoc, the P6b stem-loop of trnL intron always involves one of two different repeat motifs, either Class I or Class II, both with unresolved evolutionary histories. Here we attempt to resolve the comp...
