Abstract

Significance: Lampreys and hagfishes (cyclostomes) are the only living group of jawless vertebrates and therefore are important for the study of vertebrate evolution. We have characterized Hox clusters in the Japanese lamprey ( Lethenteron japonicum ), and shown that it contains at least six Hox clusters as compared with four Hox clusters in tetrapods. This suggests that the lamprey lineage has undergone an additional round of genome duplication compared with tetrapods. Several conserved noncoding elements (CNEs) were predicted in the Hox clusters of lamprey, elephant shark, and human. Transgenic assay of CNEs demonstrated their potential to function as cis -regulatory elements. Thus, these CNEs may represent part of the core set of cis -regulatory elements that were present in the common ancestor of vertebrates.

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.
