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). Websuccessful biotrophic infection of plants for the completion of their life cycles. A fourth group of pathogenic fungi exhibiting a biotrophic phase are the hemibiotrophs. The infection strategies of this group of fungi are characterized by an initial period of biotrophy followed by the development of secondary necrotrophic
