Phylogenetic analysis of homeobox gene sequences and homeodomain protein structures suggests that the last common ancestor of plants, fungi, and animals had at least two homeobox genes. [21] Molecular evidence shows that some limited number of Hox genes have existed in the Cnidaria since before the earliest true Bilatera , making these genes ...
Although plants have homeobox-containing genes, plant homeotic factors tend to possess MADS-box DNA binding domains. Animal genomes also possess a small number MADS-box factors. Thus, in the independent evolution of multicellularity in plants and animals, different eukaryotic transcription factor families were co-opted to serve
Hox genes are found in bilateral animals, including Drosophila (in which they were first discovered) and humans. Hox genes are a subset of the homeobox genes. The Hox genes are often conserved across species, so some of the Hox genes of Drosophila are homologous to those in humans. In general, Hox genes play a role of regulating expression of ...

Segments with maxillopeds have Hox gene 7. Fossil trilobites probably had three body regions, each with a unique combination of Hox genes. Homeobox genes, and thus the homeodomain protein motif, are found in most eukaryotes. The Hox genes, being a subset of homeobox genes, arose more recently in evolution within the animal kingdom or Metazoa.

Homeobox protein Hox-A7 is a protein that in humans is encoded by the HOXA7 gene. [5] [6] [7] In vertebrates, the genes encoding the class of transcription factors called homeobox genes are found in clusters named A, B, C, and D on four separate chromosomes. Expression of these proteins is spatially and temporally regulated during embryonic ...
