Biotrophic and necrotrophic

WebNecrotrophic pathogens are notorious for their aggressive and wide-ranging virulence strategies that promote host cell death and acquire nutrients for growth and reproduction from dead cells. This lifestyle constitutes the axis of their pathogenesis and virulence strategies and marks contrasting immune responses to biotrophic pathogens. Webbiotroph and then switched to necrotrophic lifestyle. 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).
