Included in this public database are a number of marine invertebrates: the ascidians, Ciona intestinalis (684,319 ESTs), Halocynthia roretzi (4192 ESTs) and Polyandrocarpa misakiensis (465 ESTs), the lancelet Branchiostoma floridae (277,538), the sea urchin Strongylocentrotus purpuratus (130,988 ESTs), the oyster Crassostrea virginica (9018 ESTs) and the prawn Penaeus monodon (1611 ESTs) (dbEST release July 22, 2005).
In the area of developmental biology, the discrepancy is especially marked--the development of Branchiostoma has been meticulously studied, most notably by Hatschek (1893) and Conklin (1932), whereas there have been no descriptions of the embryos and early larvae of the other two genera.
The same search parameters were also applied to identify usherin in the genomes of Homo sapiens, the domestic chicken Gallus gallus, the pufferfish Takifugu rubripes, the tunicate Ciona savignyi, the lancelet Branchiostoma floridae, the purple sea urchin Strongylocentrotus purpuratus, the limpet Lottia gigantea, and the polychaete Capitella sp.
In the head region of common lancelets Branchiostoma, the peripheral nerves show a metameric pattern similar to that of the cranial nerves in vertebrates; in addition, they show specific asymmetric innervation patterns (Franz, 1923; Kaji et al.
Sequence alignments (tBlastn) using homeodomains of proteins belonging to NK2, NK3, NK4, NK5, NK6, NK7, Msx, Hex, and Tlx families were derived from Lottia gigantea, Branchiostoma floridae, and Ciona intestinalis genome contigs available at http://genome.
