Maintenance of ancestral complexity and non-metazoan genes in two basal cnidarians
Abstract
Cnidarians are among the simplest extant animals; however EST analyses reveal that they have a remarkably high level of genetic complexity. In this article, we show that the full diversity of metazoan signaling pathways is represented in this phylum, as are antagonists previously known only in chordates. Many of the cnidarian ESTs match genes previously known only in non-animal kingdoms. At least some of these represent ancient genes lost by all bilaterians examined so far, rather than genes gained by recent lateral gene transfer.

In the citing paper
“Reflecting this ancestral core, cnidarian genes are often more similar to vertebrate genes than vertebrate genes are to those of more diverged animals like Caenorhabditis or Drosophila [50,109].”

In the citing paper
“the anemone genome harbors two families of Tx1-like non-LTR retrotransposons, Tx1-1_NV and Tx1-2_NV, inserted in 5S rRNA and U2 smRNA, respectively, at target sites identical to those of different Tx1 elements in fish (18), frog and lancelet.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
