The expression of Hox11/13 and Hox5 orthologues in the adult echinoid rudiment in the vestibula larva of Holopneustes purpurescens is described from whole mounts and sections of whole mounts after mRNA in situ hybridization. The Hox5 orthologue is HpHox5, which was isolated here. The expression of HpHox11/13 in the epithelium of the vestibule is aboral to the expression of HpHox5. HpHox5 is expressed in the epithelium of the vestibule floor where the secondary podia develop. The expression of… CONTINUE READING
