Independent Hox-cluster duplications in lampreys.
نویسندگان
چکیده
The analysis of the publicly available Hox gene sequences from the sea lamprey Petromyzon marinus provides evidence that the Hox clusters in lampreys and other vertebrate species arose from independent duplications. In particular, our analysis supports the hypothesis that the last common ancestor of agnathans and gnathostomes had only a single Hox cluster which was subsequently duplicated independently in the two lineages.

Evidence for independent Hox gene duplications in the hagfish lineage: a PCR-based gene inventory of Eptatretus stoutii.
Hox genes code for transcription factors that play a major role in the development of all animal phyla. In invertebrates these genes usually occur as tightly linked cluster, with a few exceptions where the clusters have been dissolved. Only in vertebrates multiple clusters have been demonstrated which arose by duplication from a single ancestral cluster. This history of Hox cluster duplications...
متن کاملHox cluster duplications and the opportunity for evolutionary novelties.
Hox genes play a key role in animal body plan development. These genes tend to occur in tightly linked clusters in the genome. Vertebrates and invertebrates differ in their Hox cluster number, with vertebrates having multiple clusters and invertebrates usually having only one. Recent evidence shows that vertebrate Hox clusters are structurally more constrained than invertebrate Hox clusters; th...
متن کاملThe amphioxus Hox cluster: characterization, comparative genomics, and evolution.
The amphioxus Hox cluster is often viewed as "archetypal" for the chordate lineage. Here, we present a descriptive account of the 448 kb region spanning the Hox cluster of the amphioxus Branchiostoma floridae from Hox14 to Hox1. We provide complete coding sequences of all 14 previously described amphioxus sequences and give a detailed analysis of the conserved noncoding regulatory sequence elem...
متن کاملPhylogenetic reconstruction of vertebrate Hox cluster duplications.
In vertebrates and the cephalochordate, amphioxus, the closest vertebrate relative, Hox genes are linked in a single cluster. Accompanying the emergence of higher vertebrates, the Hox gene cluster duplicated in either a single step or multiple steps, resulting in the four-cluster state present in teleosts and tetrapods. Mammalian Hox clusters (designated A, B, C, and D) extend over 100 kb and a...
متن کاملGenome Duplications and Accelerated Evolution of Hox Genes and Cluster Architecture in Teleost Fishes1
SYNOPSIS. The early origin of four vertebrate Hox gene clusters during the evolution of gnathostomes was likely caused by two consecutive duplications of the entire genome and the subsequent loss of individual genes. The presumed conserved and important roles of these genes in tetrapods during development led to the general assumption that Hox cluster architecture had remained unchanged since t...
