e.g.: 1) Enzymes that break down plant cells, e.g. cuticle and the cell wall, e.g., pectinase, cellulase, cutinase, protease, xylanase. 2) Enzymes that inactivate or modify induced defence mechanisms, e.g., phytoalexins, lignin. 3)Toxins which kill or weaken the host i.e. phytotoxins. 4) Inhibitor of the defence response enzymes or recognition system (signal transduction pathways) i.e effector proteins. 5) Substance altering the plant’s metabolism or growth e.g. Agrobacterium opine and hormone systems. 6.EPS: extracellular polysaccharide (in bacteria). 7.sRNA at least one case where regulatory RNA molecules are injected into host cells to interfere with immunity.
