Journal ArticleDOI
Use of DNA barcodes to identify flowering plants
TL;DR: Comparison of the total plastid genomes of tobacco and deadly nightshade enhanced with trials on widely divergent angiosperm taxa suggest that the sequences in this pair of loci have the potential to discriminate among the largest number of plant species for barcoding purposes.
Journal ArticleDOI
The earliest angiosperms: evidence from mitochondrial, plastid and nuclear genomes

TL;DR: This study demonstrates that Amboreella, Nymphaeales and Illiciales-Trimeniaceae-Austrobaileya represent the first stage of angiosperm evolution, with Amborella being sister to all other angiosperms, and shows that Gnetales are related to the conifers and are not sister to the angios perms, thus refuting the Anthophyte Hypothesis.
Journal ArticleDOI
Rapid duplication and loss of genes coding for the alpha chains of hemoglobin
TL;DR: Concerted evolution appears also to have occurred, but far more slowly, in the region coding for the adult beta-like chains of hemoglobin, leading to the hypothesis that the lengths of the noncoding regions are important determinants of the rates at which genes are gained and lost by intergenic recombination.
Journal ArticleDOI
Molecular evidence for genetic exchanges among ribosomal genes on nonhomologous chromosomes in man and apes
Norman Arnheim,Mark Krystal,Roy D. Schmickel,Golder N. Wilson,Oliver A. Ryder,Elizabeth A. Zimmer +5 more
TL;DR: It is found that human and ape ribosomal genes undergo concerted evolution involving genetic exchanges among nucleolus organizers on nonhomologous chromosomes.
Journal ArticleDOI
Phylogeny and Biogeography ofPanaxL. (the Ginseng Genus, Araliaceae): Inferences from ITS Sequences of Nuclear Ribosomal DNA
Jun Wen,Elizabeth A. Zimmer +1 more
TL;DR: The Himalayas and central and western China are the current centers of diversity of the ginseng genus and the low ITS sequence divergence and a close relationship among species in that region suggest that rapid evolutionary radiation may have created such a diversity of Panax in the Himalaya and in central and eastern China.
