#Unit 6. System Physiology – Plant

During infection, most bacteria remain in extracellular spaces and use a specialized mechanism, the type III secretion system (T3SS), to deliver bacterial effector proteins into the plant cell

The structural components of the T3SS are encoded by the clustered hypersensitive response and pathogenicity cluster (hrp) genes.

Many different types of bacterial Avr effectors delivered by type III secretion have been identified to be enzymes such as phosphatases, proteases, phosphoserine lyases, or E3 ubiquitin ligases that attenuate host defense signaling.

The chorismate mutase Cmu1 secreted by U. maydis to reduce the accumulation of salicylic acids and therefore reduce the intensity of the defense response at the site of infection

The nematode‐secreted peptide 16D10, which was first isolated from the soybean root‐knot nematode Meloidogyne incognita, interacts with a plant regulatory protein, stimulates root growth, and binds in planta to two SCARECROW‐like transcription factors.

The bacterial blight pathogen of rice (Oryza sativa), Xanthomonas oryzae pv. oryzae, secretes a highly conserved sulfated peptide called Ax21, which mediates quorum sensing by controlling Xanthomonas motility, biofilm formation, and virulence.
