Ancient Genome Duplications Did Not Structure the Human Hox-Bearing Chromosomes
(East Carolina University, 2001-05)The fact that there are four homeobox (Hox) clusters in most vertebrates but only one in invertebrates is often cited as evidence for the hypothesis that two rounds of genome duplication by polyploidization occurred early ... -
Arthropod Phylogenetics in Light of Three Novel Millipede (Myriapoda: Diplopoda) Mitochondrial Genomes with Comments on the Appropriateness of Mitochondrial Genome Sequence Data for Inferring Deep Level Relationships
(2013)Background Arthropods are the most diverse group of eukaryotic organisms, but their phylogenetic relationships are poorly understood. Herein, we describe three mitochondrial genomes representing orders of millipedes for ... -
Digits Lost or Gained? Evidence for Pedal Evolution in the Dwarf Salamander Complex ( Plethodontidae)
(2012)Change in digit number, particularly digit loss, has occurred repeatedly over the evolutionary history of tetrapods. Although digit loss has been documented among distantly related species of salamanders, it is relatively ... -
Evolution of Plant Nucleotide-Sugar Interconversion Enzymes
(2011)Nucleotide-diphospho-sugars (NDP-sugars) are the building blocks of diverse polysaccharides and glycoconjugates in all organisms. In plants, 11 families of NDP-sugar interconversion enzymes (NSEs) have been identified, ... -
Phylogeny and Classification of the Trapdoor Spider Genus : An Integrative Approach to Evaluating Taxonomic Hypotheses
(2010)Background Revised by Bond and Platnick in 2007, the trapdoor spider genus Myrmekiaphila comprises 11 species. Species delimitation and placement within one of three species groups was based on modifications of the male ...
