Expression of HOX Cluster Genes in Early Larval Development of Sea Urchin Strongylocentrotus intermedius (Echinodermata, Echinoidea)
Expression of 11 genes of the Hox cluster (SiHox1, 2, 3, 5, 6, 7, 8, 9/10, 11/13a, 11/13b, and 11/13c) was assessed in the sea urchin Strongylocentrotus intermedius at early developmental stages, including the blastula (13 h post fertilization (hpf)), gastrula (35 hpf), prism (46 hpf), and pluteus (4 and 9 days post fertilization (dpf)) stages. Expression of SiHox7, 11/13b, and 11/13c was observed at the blastula stage; early activation of 11/13c was detected for the first time in regular sea urchins. The expression level was very low at the gastrula and prism stages. The pluteus stage showed a significant increase in expression of all Hox cluster genes. Deviations from temporal collinearity of Hox gene expression in echinoderms are discussed.
