Steady-state stable solutions for mating projection growth: Projection shape and cell wall expansion.
(A,C,E,G) Mating projection shape (A), as well as the spatial profiles of the cell wall expansion rate 
(C), curvature κs (E) and cell wall thickness h (G), 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), with the exception of the wall thickness h(s) and the shape r(s), which are normalized by the limiting values far away from the apical region, H and R respectively. 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 
(D) and κ0 ≡ κs(s = 0) (F), is shown for the different values of the parameters for which stable states exist. The variation of the projection radius and wall thickness away from the apical region, R (B) and H (H) respectively, are shown as a function of the parameters as well.
