Once inside the plant, one of three main attack strategies is deployed specific feature of interaction given;

B) Biotrophy
C) Hemibiotrophy
i) where the plant cells remain alive throughout infection
ii) where the plant cells are killed in advance of infection 
iii) extensive plant tissue damage at initial stages
