The dynamics of vertebrate homeobox gene evolution: gain and loss of genes in mouse and human lineages

Ying-fu Zhong, Peter WH Holland BMC Evolutionary Biology 2011, 11:169 (16 June 2011)

The genome evolution of rodents reveals greater homeobox gene loss in comparison to primates and may provide clues to the evolution of developmental mechanisms and the link between genomic and phenotypic evolution.

Domain duplication, divergence, and loss events in vertebrate Msx paralogs reveal phylogenomically informed disease markers

John R Finnerty, Maureen E Mazza, Peter A Jezewski BMC Evolutionary Biology 2009, 9:18 (20 January 2009)

The metazoan homeodomain MSX gene family, associated with various human genetic disorders, originated from a MetaHox ancestor and underwent duplication and divergence of functional domains resulting in the evolution of various genes including Hox and ParaHox.

Are we degenerate tetraploids? More genomes, new facts

Amir Abbasi Biology Direct 2008, 3:50 (10 December 2008)

The sequence data from an expanding range of animals provide no support for hypothesis relating the origin of vertebrates with whole genome duplications, but favors a model of animal genome evolution in which small-scale duplications predominate.

Classification and nomenclature of all human homeobox genes

Peter WH Holland, H Booth, Elspeth A Bruford BMC Biology 2007, 5:47 (26 October 2007)

A comprehensive survey of human homeobox genes and pseudogenes has discovered previously unknown loci, leading to a revised classification of homeobox genes using names that reflect their evolutionary relationships to other loci.

The innate immune repertoire in Cnidaria - ancestral complexity and stochastic gene loss

David J Miller, Georg Hemmrich, Eldon E Ball, David C Hayward, Konstantin Khalturin, Noriko Funayama, Kiyokazu Agata, Thomas CG Bosch Genome Biology 2007, 8:R59 (16 April 2007)

Analysis of genomic resources available for cnidarians revealed that several key components of the vertebrate innate immune repertoire are present in representatives of the basal cnidarian class Anthozoa, but are missing in Hydra, a member of the class Hydrozoa, indicating ancient origins for many components of the innate immune system.
