WebNov 26, 2015 · Necrotrophy is defined as growth and nutrition of the pathogen on dead or dying plant material. Hemibiotrophs share characteristics with both biotrophs and necrotrophs, initially invading cells that are maintained alive prior to a transition to a necrotrophic life style in which nutrients are obtained from killing host cells. 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.
