Infection stages of C. purpurea strains at the time point of sample collection. a The wild-type Cp20.1 (black line) enters the ovary at the stigmatic hairs (s), passes the transmitting tissue (tm), grows around the ovule (o) and almost reaches the base of the ovary. b The virulence-attenuated mutant Δcptf1 (grey continuous and dashed line) also penetrates the stigmatic hairs but reaches the base only sparsely. Δcpcdc42 (grey continuous line) penetrates the stigmatic hairs but does not enter the ovarian cap
