“…Despite varying degrees of degeneration of the Hox cluster in Drosophila (Von Allmen et al , 1996; Lewis et al , 2003) and nematodes (Aboobaker & Blaxter, 2003), all invertebrate metazoans are presumed to have a single Hox cluster (Holland & Garcia‐Fernandez, 1996; Halanych & Passamaneck, 2001; Long & Byrne, 2001; Seo et al , 2004; Cho et al , 2006). This also contrasts sharply with that of the vertebrates, where multiple Hox clusters are found.…”

With their power to shape animal morphology, few genes have captured the imagination of biologists as much as the evolutionarily conserved members of the Hox clusters. Hox genes encode transcription factors that play a key role in specifying the body plan in metazoans and are therefore essential in explaining patterns of evolutionary diversity. While each Hox cluster contains the same genes among the different mammalian species, this does not happen in ray-finned fish, in which both the number and organization of Hox genes and even Hox clusters are variable. Teleost fishes provide the first unambiguous support for ancient whole-genome duplication (third round) in an animal lineage. The number of genes differs in each cluster as a result of increased freedom to mutate after duplication. This has also allowed them to diverge and to adopt novel developmental roles. In this review, the authors have firstly focused on broadly outlining the duplication of Hoxgenes in fishes and discussing how comparative genomics is elucidating the molecular changes associated with the evolution of Hox genes expression and developmental function in the teleost fishes.Additional related research aspects, such as imaging of roles of microRNAs, chromatin regulation and evolutionary findings are also discussed.

“…For Capitella , 11 Hox genes ( lab , pb , Hox3 , Dfd , Scr , lox5 , Antp , lox4 , lox2 , Post2 , post1 ) corresponding to 11 different paralog groups were detected, and the presence of these genes are regarded as ancestral for lophotrochozoans in general (Fröbius et al 2008 ;Simakov et al 2013 ). For many other annelids, information about the Hox gene complement are available through PCR and cloning studies; however, genomic organization and absence of genes cannot be derived from this approach (Dick and Buss 1994 ;Snow and Buss 1994 ;Irvine et al 1997 ;Cho et al 2003Cho et al , 2006Kulakova et al 2007 ;Bleidorn et al 2009 ).
