<i>sdn-1</i> mutations enhance <i>lin-44</i> gastrulation defects.
No full text<p>A: In <i>C</i>. <i>elegans</i>, gastrulation is initiated by the inward migration of the endodermal precursor cells Ea and Ep (black asterisks). In <i>sdn-1</i> and <i>ptp-3</i> mutant animals, the cells ingress, become completely surrounded by neighboring cells, then divide laterally (white asterisks). Note that Ea and Ep are completely internalized prior to the lateral cell division. In <i>lin-44</i> and <i>sdn-1</i> mutants, Ea/Ep ingression is often asynchronous. In addition, some <i>lin-44</i> embryos show a more severe phenotype, where the Ea/Ep cells completely fail to ingress. The subsequent lateral cell division positions two of the daughter cells onto the surface of the embryo, generating a “<u>G</u>ut on the <u>ex</u>terior”, or Gex phenotype [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0121397#pone.0121397.ref077" target="_blank">77</a>]. Similar but more penetrant defects are observed in <i>lin-44; sdn-1</i> double mutants. B: Summary of Ea and Ep cell ingression behavior by genotype. The <i>lin-44; sdn-1</i> double mutants exhibit a higher rate of Ea and Ep ingression defects than either single mutant. C: Relative timing of developmental milestones as a function of genotype. Note the <i>lin-44; sdn-1</i> double mutants have a significantly longer period in which the gastrulation cleft is open.</p
