    Abstract

    Unique expression patterns of the 5′ HoxA genes are associated with the evolution and development of novel features including claspers in cartilaginous fishes, modified pectoral fins in batoids, and the yolk sac extension in Cypriniformes. Here, we demonstrate a role forHoxA11aandHoxA13ain demarcating the hindgut in fishes of the family Gobiidae, including a novel sphincter called the intestinal rectal sphincter (IRS). Disruption of 5′ HoxA expression, via manipulation of retinoic acid signaling, results in failure of the IRS and/or vent to develop. Furthermore, exposure to HoxA disruptors alters 5′ HoxA expression, in association with developmental phenotypes, demonstrating a functional link between 5′ HoxA expression and development of a novel feature in the bluebanded goby,Lythrypnus dalli.
