(A) Time evolution of the PSM length at different speed of PSM shortening u_a. (B) Kymographs of vorticity for washout time at t_wash-out = 0 min (0 somite-stage, ss: left) and 270 min (9 ss: right). The black triangles indicate timing of washout. The wshite solid lines indicate the position of the anterior end of the PSM x_a. Vorticity across the right PSM is shown. Trajectories of counter-clockwise vortices for t_wash-out = 0 min and those of clockwise vortices for t_wash-out = 270 min are presented. (C) Dependence of time to PLD, PLD – t_wash-out, on u_a for different washout timing t_wash-out. Medians for 100 realizations of simulations are plotted. (D-F) Dependences of time to FRS, FRS – t_wash-out (blue) and time to PLD, PLD – t_wash-out (green) on t_wash-out for different values of u_a. (D) u_a = 0.1, (E) 0.4 and (F) 0.66. The box-whisker plot indicates (0.05, 0.25, 0.75, 0.95) quantiles of times to FRS and PLD for 100 realizations of simulations. The white bars indicate median.
