  1. Holland L, Ocampo Daza D. A new look at an old question: when did the second whole genome duplication occur in vertebrate evolution?. Genome Biol. 2018;19:209 pubmed publisher
    ..Comparison of this karyotype to the 17 chordate linkage groups previously inferred in the ancestral chordate indicated that two whole genome duplications probably occurred in the lineage preceding the ancestral vertebrate. ..
  2. Ono H, Koop D, Holland L. Nodal and Hedgehog synergize in gill slit formation during development of the cephalochordate Branchiostoma floridae. Development. 2018;145: pubmed publisher
    ..Thus, during the neurula stage, Nodal and Hh cooperate in gill slit development - Hh mediates gill slit formation and Nodal establishes their left-right position. ..
  3. Yue J, Yu J, Putnam N, Holland L. The transcriptome of an amphioxus, Asymmetron lucayanum, from the Bahamas: a window into chordate evolution. Genome Biol Evol. 2014;6:2681-96 pubmed publisher
    ..lucayanum and B. floridae. The divisions between cephalochordates and vertebrates, and that between chordates and the hemichordate plus echinoderm clade likely occurred before the Cambrian. ..
  4. Holland L, Onai T. Analyses of gene function in amphioxus embryos by microinjection of mRNAs and morpholino oligonucleotides. Methods Mol Biol. 2011;770:423-38 pubmed publisher
    ..This chapter details methods for microinjection of amphioxus eggs with mRNAs or morpholino antisense oligonucleotides to analyze gene networks operating in early development. ..
  5. Holland L. The origin and evolution of chordate nervous systems. Philos Trans R Soc Lond B Biol Sci. 2015;370: pubmed publisher
    ..The minority view is that this ancestor had no nerve cord; those in chordates and hemichordates evolved independently. New techniques such as phylostratigraphy may help resolve this conundrum. ..
  6. Holland L. Evolution of basal deuterostome nervous systems. J Exp Biol. 2015;218:637-45 pubmed publisher
    ..The apparent loss of this opposition in hemichordates is, therefore, compatible with the scenario, suggested by Dawydoff over 65 years ago, that a true centralized nervous system was lost in hemichordates. ..
  7. Holland L. Tunicates. Curr Biol. 2016;26:R146-52 pubmed publisher
    ..An outstanding question is what happened to allow tunicates to evolve so much faster than their nearest relatives, cephalochordates and vertebrates. ..
  8. Holland L. Chordate roots of the vertebrate nervous system: expanding the molecular toolkit. Nat Rev Neurosci. 2009;10:736-46 pubmed publisher
    ..Recent advances in genomics have provided insights into the elaboration of the molecular toolkit at the invertebrate-vertebrate transition that may have facilitated the evolution of these vertebrate characteristics. ..
  9. Holland L, Short S. Alternative splicing in development and function of chordate endocrine systems: a focus on Pax genes. Integr Comp Biol. 2010;50:22-34 pubmed publisher
