Developmental expression of the hemichordate otx ortholog
The phylogenetic location of hemichordates is unique because they seem to fill an evolutionary gap between echinoderms and chordates. We report here characterization of Pf-otx, a hemichordate ortholog of otx, with its embryonic and larval expression pattern. Pf-otx is initially expressed in the vegetal plate of the blastula. Expression remains evident in the archenteron through gastrulation and...
متن کاملThe notochord
the paper, I immediately understood that it was going to be possible to use Agrobacterium to make transgenic plants and that would, in turn, create many new opportunities. I concluded that plant molecular genetics was poised to take off and that insight, plus some nudging from Shauna, tipped me over the edge. What is your greatest frustration? I am frustrated by the influence of political organ...
متن کاملAn Early Cambrian Hemichordate Zooid
Hemichordates are known as fossils from at least the earliest mid-Cambrian Period (ca. 510 Ma) and are well represented in the fossil record by the graptolithinid pterobranchs ("graptolites"), which include the most abundantly preserved component of Paleozoic macroplankton. However, records of the soft tissues of fossil hemichordates are exceedingly rare and lack clear anatomical details. Galea...
متن کاملA simple molecular model of neurulation.
A molecular model for the morphogenesis of the central nervous system is built and solved by computer. The formalism rests on molecular-biological data gathered from insects and vertebrates during neural differentiation and neuronal fate specification. Two genetic, hierarchically organized switches are introduced, one associated with f1p4al tissue formation, and the other with neuronal specific...
متن کاملRegeneration in the hemichordate Ptychodera flava.
When the body of P. flava is severed, the animal has the ability to regenerate its missing anterior or posterior as appropriate. We have focused on anterior regeneration when the head and branchial regions are severed from the body of the worm. After transection, the body wall contracts and heals closed in 2 to 3 days. By the third day a small blastema is evident at the point of closure. The bl...
