#Unit 6. System Physiology – Plant

Phytopathogenic bacteria reside within the intercellular spaces of plant organs or in the xylem and many damage plant tissues by secreting toxins, extracellular polysaccharides (EPSs), or cell wall‐degrading enzymes.

Phytoplasmas are specialized bacteria that are obligate parasites of the phloem tissue. They are mainly
spread by insects in the families Cicadellidae (leaf hoppers),
Fulgoroidae (plant hoppers), and Psyllidae (jumping plant
lice).
