Post-transcriptional restriction of gene expression in sea urchin interspecies hybrid embryos.
The synthesis of many paternal species-specific proteins is reduced in all stages of sea urchin interspecies hybrid embryos, due to the reduced amounts of some paternal mRNA species in hybrid embryos compared with the embryos of the paternal species (Tufaro and Brandhorst 1982). Possible explanations for this restriction were tested. Cloned cDNAs were selected that were specific for paternal RN...

متن کاملPattern of Brachyury gene expression in starfish embryos resembles that of hemichordate embryos but not of sea urchin embryos
Echinoderms, hemichordates and chordates are deuterostomes and share a number of developmental features. The Brachyury gene is responsible for formation of the notochord, the most defining feature of chordates, and thus may be a key to understanding the origin and evolution of the chordates. Previous studies have shown that the ascidian Brachyury (As-T and Ci-Bra) is expressed in the notochord ...
متن کاملInducible expression of a cloned heat shock fusion gene in sea urchin embryos.
A fusion gene construct, in which the coding sequence for bacterial chloramphenicol acetyltransferase (CAT; acetyl-CoA: chloramphenicol 3-O-acetyltransferase, EC 2.3.1.28) was placed under the control of the regulatory region of the Drosophila gene encoding the 70-kilodalton heat shock protein [Di Nocera, P.P. & Dawid, I.B. (1983) Proc. Natl. Acad. Sci. USA 80, 7095-7098], was microinjected int...
متن کاملEST analysis of gene expression in early cleavage-stage sea urchin embryos.
A set of 956 expressed sequence tags derived from 7-hour (mid-cleavage) sea urchin embryos was analyzed to assess biosynthetic functions and to illuminate the structure of the message population at this stage. About a quarter of the expressed sequence tags represented repetitive sequence transcripts typical of early embryos, or ribosomal and mitochondrial RNAs, while a majority of the remainder...
