Extended Data Fig. 6: Mechanical invasion exhibits three stages.

Two additional examples of total indentation force Fi as a function of time (t) for the mechanical invasion of P. infestans - 14:3 eGFP into 0.58 MPa elastomer substrates, exhibiting three temporal stages (see Fig. 1a): I) germ tube growth is observed but no detectable surface deformations occur, II) pressure application increases until a fracture nucleates, III) pathogen invades into the crack opening, during which the crack propagates at relatively constant force.
