Graphical repersentation of plant defense system

The schematic figure illustrates the intricate relations between plant innate immunity (PTI, ETI), ETS-related resistance response and the regulation of the genes involved in plant-pathogen interactions. On pthogen attack, plasma membrane-localized receptors (PRR) based on apthogen type such as bacteria, fungi or virus recognize the presence of PAMP’s or effectors in the extracellular environment and induce PAMPs Triggered Immunity (PTI), Effector Triggered immunity (ETI). Effector are any regulatory molecules secreted by pathogens which modifies the host protein to establish their growth and initiate Effecctor triggred susceptibility (ETS). R- ressistance proteins.
