It has been suggested that effective defense against biotrophic pathogens is largely due to programmed cell death in the host, and to associated activation of defense responses regulated by the salicylic acid-dependent pathway.

The biotrophic phase is mostly confined to a single epidermal cell attacked by the infection hypha, whereas the necrotrophic phase begins after infection of the mesophyll tissue followed by host cell death as a consequence of toxin secretion (Apoga et al., 2002; Acharya et al., 2011). chip city long island
