Abstract:
The genus Pimpinella L. comprises about 150 species, being one of the largest genera within the family Apiaceae (subfamily Apioideae). Previous molecular phylogenetic studies have shown that Pimpinella is a taxonomically complex group. In this study, evolutionary relationships among representatives from Western Europe have been inferred from phylogenetic analyses of nuclear ribosomal DNA internal transcribed spacer (ITS 1 and ITS 2) and plastid sequences (trnL intron and the trnL-F spacer), with a representative sampling included (168 accessions in the ITS analysis, representing 158 species; and 42 accessions in the cpDNA analysis representing 35 taxa of Pimpinella and closely related species). All analyses resolved that Pimpinella is a non-monophyletic group, and Pimpinella's taxa that grow in Western Europe are part of phylogenetically independent groups that correspond to three different tribes of the subfamily Apioideae: Pimpinelleae (core group), Pyramidoptereae and Smyrnieae.

Western Blotting
The technique begins with separating proteins from the sample using sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE), followed by protein transfer, immunoblotting, and finally, protein detection.
