WebAug 29, 2024 · Biotrophic plant pathogenic fungi have an exceptional lifestyle that supports nutrient acquisition from cells of a living host and are fully dependent on the host for successful completion of their life cycle. The haustorium, a specialized infection structure, is the key organ for biotrophic fungal pathogens. WebA combination of biotrophic and necrotrophic growth is found in some fungi that require living plant tissue initially. These fungi often form haustoria and draw their nutrients from living plant tissue. As their life cycle progresses, they proceed to kill their host. They subsequently feed off the dead tissue.
