WebAbstract Fungi have multiple trophic behaviors, including biotrophism (parasitism on living hosts), necrotrophism (parasitism through killing host tissues), and saprotrophism (feeding on decaying organic matter).

Webbiotrophism (Heath, 1995). One approach to identifying the fungal determinants for biotrophism is to isolate in planta induced genes (PIGs). In an earlier study, Liu et al.
