The Arabidopsis arenosa complex is closely related to the model plant Arabidopsis thaliana. Species and subspecies in the complex are mainly biennial, predominantly outcrossing, herbaceous, and with a distribution range covering most parts of latitudes and the eastern reaches of Europe. In this study we present the first comprehensive evolutionary history of the A. arenosa species complex, cove...

Chloroplast trnL-F sequence data, nuclear ribosomal internal transcribed spacer (ITS) sequence data, and morphology were used to analyze phylogenetic relationships among members of the subtribe Strobilanthinae. Parsimony and maximum likelihood analyses of trnL-F indicate that the Strobilanthinae are a monophyletic group. While parsimony analysis of ITS recovers a nonmonophyletic subtribe, maxim...

Direct sequencing of polymerase chain reaction products is now an expanding area of plant systematics and evolution. Within angiosperms the rbcL gene has been widely sequenced and used for inferring plant phylogenies at higher taxonomic levels. Unfortunately rbcL does not usually contain enough information to resolve relationships between closely related genera, such as Hordeum, Triticum, and A...

An overview on legal regulation, taxonomy, and botanical and chemical methods of analysis of marijuana are provided. Emphases are placed on the applications of the recently developed molecular biology methods to the identification and characterization of marijuana samples. Procedures for the extraction of plant DNA, DNA amplification, restriction analysis, and sequence analysis are reviewed. Th...

The ability to discriminate all species is the ultimate target in barcoding. The Mediterranean basin is a center of origin for legumes and thus they have played a key role in feeding the Mediterranean population. It is also a region with important protected designation of origin and protected geographical indication legumes that provide income in rural areas. We evaluated the use of two ch...

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...
