Arthropod evolution: Same Hox genes, different body plans
نویسنده
چکیده
Morphological evolution is conventionally studied by direct comparison of morphological characteristics in different organisms. Recently it has also become possible to study the evolution of developmental processes and gene functions, and to speculate about links between the evolution of genes and the evolution of morphology. One of the cases that has attracted particular interest is the relationship between the evolution of Hox genes and the evolution of body plans in higher metazoans, particularly in arthropods.

Evolution of the entire arthropod Hox gene set predated the origin and radiation of the onychophoran/arthropod clade
BACKGROUND Dramatic changes in body size and pattern occurred during the radiation of many taxa in the Cambrian, and these changes are best documented for the arthropods. The sudden appearance of such diverse body plans raises the fundamental question of when the genes and the developmental control systems that regulate these designs evolved. As Hox genes regulate arthropod body patterns, the e...
متن کاملArthropod Evolution: Brine shrimp add salt to the stew
The expression patterns of homeotic genes in a crustacean-the brine shrimp Artemia franciscana-provide a new perspective on the evolution of arthropod body plans. The ancestral arthropod is thought to have had a body made up of a series of similar segments, each bearing an unspecialized limb. A major trend in arthropod evolution has been an ever-increasing specialization and regional-ization of...
متن کاملComparative developmental genetics and the evolution of arthropod body plans.
The arthropods display a wide range of morphological diversity, varying tagmosis, as well as other aspects of the body plan, such as appendage and cuticular morphology. Here we review the roles of developmental regulatory genes in the evolution of arthropod morphology, with an emphasis on what is known from morphologically diverse species. Examination of tagmatic evolution reveals that these ch...
متن کاملFunctional evolution of the Ultrabithorax protein.
The Hox genes have been implicated as central to the evolution of animal body plan diversity. Regulatory changes both in Hox expression domains and in Hox-regulated gene networks have arisen during the evolution of related taxa, but there is little knowledge of whether functional changes in Hox proteins have also contributed to morphological evolution. For example, the evolution of greater numb...
متن کاملExploring the myriapod body plan: expression patterns of the ten Hox genes in a centipede.
The diversity of the arthropod body plan has long been a fascinating subject of study. A flurry of recent research has analyzed Hox gene expression in various arthropod groups, with hopes of gaining insight into the mechanisms that underlie their evolution. The Hox genes have been analyzed in insects, crustaceans and chelicerates. However, the expression patterns of the Hox genes have not yet b...
