Mechanical feedback coordinates cell wall expansion and assembly in yeast mating morphogenesis
Fig 1
Schematic diagrams of relevant events and quantities in mating projection growth.
(A) Transmitted light image of a S. cerevisiae cell growing a mating projection in the presence of α-factor. Scale bar, 2μm. (B-D) Sketch of molecular events leading to the delivery and activation of cell wall synthases Fks1/2 at the apex. See main text and Table 1 for definitions of parameters. (E) Geometry of the system and definition of the relevant variables. (F) Sketch depicting the increasing cell wall viscosity and decreasing cell wall assembly away from the apex. The inset depicts local normal force balance at the cell wall. All variables are defined in the main text.
