We report the potential phylogenetic utility of DNA sequence data from the last 700 bp of a ca. 1-kb intron of the MADS-box gene pistillata from a sampling of Sphaerocardamum species and other Brassicaceae. These results are compared with nrDNA ITS and the chloroplast trnL intron for the same taxa to demonstrate the potential phylogenetic utility of this pistillata intron and to identify potent...

Nucleotide sequence data from the chloroplast rbcL gene and the trnL-trnF intergenic spacer of 58 species in 38 genera were used to infer the phylogenetic affinities of Monimiaceae to other Laurales, and to assess whether the family in the traditional wide sense is monophyletic. Besides Monimiaceae, the Laurales comprise Calycanthaceae, Gomortegaceae, Hernandiaceae, and Lauraceae. Magnoliaceae ...

Although plastid DNA has been widely explored as a marker of choice for phylogeny and phylogeography studies, little is known about its utility for examining relationships between closely related species. The slow evolutionary rates inherent to chloroplast (cp) DNA make it difficult to perform lower level taxonomic analyses, particularly at the population level. We characterized the nucleotide ...
