Morphologic phenotypes of <i>zip7</i>-deficient embryos and Zn²⁺ (50 µM) rescue at 72 hpf.

<p>Lateral views (anterior to the left) of embryos at 72 hpf. (A)Wild type with control-MO microinjection (2 nL, 10 ng). (B) Wild type with <i>zip7</i>-MO microinjection (2 nL, 10 ng). (C) Wild type with <i>zip7</i>-MO microinjection (2 nL, 10 ng) hatching in the presence of Zn²⁺ (50 µM). (D) Statistical analysis of microinjection <i>zip7</i>-MO and Zn²⁺ phenotype.
