Relationship between cell behavior and tissue elongation across genotypes. (A-C) Tissue elongation versus the number of (A) total cell rearrangements, (B) T1 transitions per cell and (C) rosettes per cell. (D) Tissue elongation versus the cell width-to-height ratio at the end of axis elongation (t=30 min). A single mean value was obtained for each embryo and the mean±s.e.m. between embryos is shown. n=3-8 embryos/genotype, except myosin II where n=2. Pearson's correlation coefficient (r) is shown.
