Phytophthora capsici–host interaction studies on the solanaceous model Nicotiana benthamiana. (A) Infection time course assay performed on detached N. benthamiana leaves. Photographs were taken at the time points indicated. Infection features an initial biotrophic phase in which haustoria are observed in colonized tissues. On further ingress (18–42 h), P. capsici lesions become visible and affected tissues collapse. In the later (>66 h) time stages, sporulation ensues and tissue is fully mascerated. (B) Schematic representation of the infection process on N. benthamiana leaves.
