Steady-state stable solutions for mating projection growth: Cell wall assembly via Fks1/2.
Cell wall assembly via Fks1/2. (A,C,E,G) Total Fks1/2 density ρA + ρI (A), fraction of active Fks1/2, ρA/(ρA + ρI) (C), active Fks1/2 density (E) and inactive Fks1/2 density (E), for different values of the mechanical feedback strength Γ and the ratio λX/λm = (PρwλX)/(12μ0mwρ0kp). All insets show a different scaling of each magnitude, with the arclength normalized by the projection radius R and each quantity normalized by its value at the projection tip (s = 0). The color code indicates the different parameter values, shown as dots of the same color in the parameter space right to each panel. Increasing orange and blue tones of the dots corresponds to decreasing Γ and increasing (PρwλX)/(12μ0mwρ0kp), respectively (arrows in Fig 2E). (B,D,F,H) The variation of the apical value of each magnitude, namely (B),
(D),
(F) and
(H), is shown for the different values of the parameters for which stable states exist.
