Modelling of Yeast Mating Reveals Robustness Strategies for Cell-Cell Interactions

Reduced mating efficiency for supersensitive cells.
(A) Polarization plots of u2 showing four pairs of supersensitive mating cells at the end time point. The spatial distribution of u2 is represented according to the normalized color map on the right. The 0’s indicate that none of the matings were successful. Both cells had β2 = 2.5. (B) Distance plot showing trajectories from four sample supersensitive mating simulations. The distance between polarisomes was plotted as a function of time. The distances did not steadily decrease as was observed in the normal sensitivity simulations. The four plots are color-coded to match with the polarization plots. (C) Direction plot for supersensitive cell mating simulations. Many of the data points lie far off the diagonal indicating that the cells are not pointing toward each other; the average distance from the diagonal is 0.68 radians compared to 0.12 for the normal sensitivity matings.
