Ciliary photoreceptors in the cerebral eyes of a protostome larva
Passamaneck, Yale J.; Furchheim, Nina; Hejnol, Andreas; Martindale, Mark Q.; Lüter, Carsten (Peer reviewed; Journal article, 2011-03-01)Background: Eyes in bilaterian metazoans have been described as being composed of either ciliary or rhabdomeric photoreceptors. Phylogenetic distribution, as well as distinct morphologies and characteristic deployment of ... -
Coordinated spatial and temporal expression of Hox genes during embryogenesis in the acoel Convolutriloba longifissura
Hejnol, Andreas; Martindale, Mark Q. (Journal article; Peer reviewed, 2009-10-01)Background: Hox genes are critical for patterning the bilaterian anterior-posterior axis. The evolution of their clustered genomic arrangement and ancestral function has been debated since their discovery. As acoels appear ... -
Development of the larval anterior neurogenic domains of Terebratalia transversa (Brachiopoda) provides insights into the diversification of larval apical organs and the spiralian nervous system
Santagata, Scott; Resh, Carlee; Hejnol, Andreas; Martindale, Mark Q.; Passamaneck, Yale J. (Peer reviewed; Journal article, 2012-01-24)Background: Larval features such as the apical organ, apical ciliary tuft, and ciliated bands often complicate the evaluation of hypotheses regarding the origin of the adult bilaterian nervous system. Understanding how ... -
Expression of multiple Sox genes through embryonic development in the ctenophore Mnemiopsis leidyi is spatially restricted to zones of cell proliferation
Schnitzler, Christine E.; Simmons, David K.; Pang, Kevin; Martindale, Mark Q.; Baxevanis, Andreas D. (Journal article; Peer reviewed, 2014-04-24)Background: The Sox genes, a family of transcription factors characterized by the presence of a high mobility group (HMG) box domain, are among the central groups of developmental regulators in the animal kingdom. They are ... -
Gene expression in bryozoan larvae suggest a fundamental importance of pre-patterned blastemic cells in the bryozoan life-cycle
Fuchs, Judith; Martindale, Mark Q.; Hejnol, Andreas (Peer reviewed; Journal article, 2011-06-06)Background: Bryozoa is a clade of aquatic protostomes. The bryozoan life cycle typically comprises a larval stage, which metamorphoses into a sessile adult that proliferates by asexual budding to form colonies. The homology ... -
Lim homeobox genes in the Ctenophore Mnemiopsis leidyi: the evolution of neural cell type specification
Simmons, David K.; Pang, Kevin; Martindale, Mark Q. (Journal article; Peer reviewed, 2012-01-13)Background: Nervous systems are thought to be important to the evolutionary success and diversification of metazoans, yet little is known about the origin of simple nervous systems at the base of the animal tree. Recent ... -
Mesodermal gene expression during the embryonic and larval development of the articulate brachiopod Terebratalia transversa
Passamaneck, Yale J.; Hejnol, Andreas; Martindale, Mark Q. (Journal article; Peer reviewed, 2015-04-11)Background: Brachiopods undergo radial cleavage, which is distinct from the stereotyped development of closely related spiralian taxa. The mesoderm has been inferred to derive from the archenteron walls following gastrulation, ... -
Molecular patterning during the development of Phoronopsis harmeri reveals similarities to rhynchonelliform brachiopods
Andrikou, Carmen; Passamaneck, Yale J; Lowe, Christopher J.; Martindale, Mark Q.; Hejnol, Andreas (Journal article; Peer reviewed, 2019)Background: Phoronids, rhynchonelliform and linguliform brachiopods show striking similarities in their embryonic fate maps, in particular in their axis specification and regionalization. However, although brachiopod ...
