Expression of Pigment Cell-Specific Genes in the Ontogenesis of the Sea Urchin Strongylocentrotus intermedius
Figure 5
Effect of shikimic acid (ShA) on the larval morphology of the sea urchin S. intermedius. Disturbances in embryo development after 8 days of incubation with ShA. ShA was added to (a) zygotes; (b) embryos of the blastula stage; (c) embryos of the gastrula stage. ShA concentrations tested: 1–0.1 mM, 2–0.5 mM, and 3–2.0 mM. Nomarski’s optics. Bar, 50 μm.
