Figure 1. — The first asymmetric division in C. elegans and C. briggsae embryos. (A) Snapshots from DIC recordings of C. elegans and C. briggsae wild-type strains. Time is shown relative to anaphase onset (t = 0 s). Anterior is to the left. Broken lines are positioned at 50% of embryo length. Arrows show the asters. Bars, 10 µm. (B) Drawing of a one-cell stage embryo. The horizontal axis corresponds to the A/P axis: 0% defines the anterior pole of the cell. The transverse axis is in red: 0% is the center of the cell. On the bottom panel, the mean position of the centrosome along the A/P axis is shown relative to anaphase onset (t = 0 s) for both species. –50 s corresponds to metaphase and 125 s to cytokinesis onset. Solid and broken lines represent the posterior and anterior centrosomes, respectively.
