Meiotic Progression and MAP Kinase Activation Is Restored after Shift to Permissive Temperature

<div><p>Dissected gonads were stained with DAPI (left column) and α-diP MAP kinase (middle column). Boxed area in left column is enlarged in right column (inset) to show germ cell morphology during meiotic progression. Asterisks indicate distal end of germ line. Arrowheads indicate nuclei in diakinesis. Brackets indicate region with activated MAP kinase staining.</p><p>(A) Gonads from control animals.</p><p>(B) <i>mpk-1</i> gonads at 26 °C (0 h) and following shift to 15 °C (3–12 h).</p><p>All gonads also carry <i>fem-1(hc17)</i> and <i>unc-79(e1068)</i> alleles. Scale bar, 20 μm.</p>
