#Unit 6. System Physiology – Plant
Pathogen evades plant by penetration of surface layers directly using mechanical pressure or enzymatic attack, some pass through natural openings, such as stomata or lenticels, and others only enter through wounded tissue. Once inside the plant, one of three main attack strategies is deployed specific feature of interaction given;
A) Necrotrophy
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
iv) where the pathogen initially keeps cells alive but at later stages of the infection, kills them
