Many plant pathogens subvert host immunity by injecting compositionally diverse but
functionally similar repertoires of cytoplasmic effector proteins. The bacterial pathogen …

The plant innate immune system comprises local and systemic immune responses. Systemic
plant immunity develops after foliar infection by microbial pathogens, upon root colonization …

Closely related pathogens may differ dramatically in host range, but the molecular, genetic,
and evolutionary basis for these differences remains unclear. In many Gram-negative …

RNA-DEPENDENT RNA POLYMERASE 6 (RDR6) is a key RNA silencing factor initially
characterized in transgene silencing and virus resistance. This enzyme also contributes to …

A large number of proteins transferred by the Legionella pneumophila Dot/Icm system have
been identified by various strategies. With no exceptions, these strategies are based on one …

Diverse Gram-negative pathogens like Pseudomonas syringae employ type III secreted
effector (T3SE) proteins as primary virulence factors that combat host immunity and promote …

Legionella pneumophila is a bacterial pathogen of amoebae and humans. Intracellular
growth requires a type IVB secretion system that translocates at least 200 different proteins …

Pseudomonas aeruginosa strain PA14 is an opportunistic human pathogen capable of
infecting a wide range of organisms including the nematode Caenorhabditis elegans. We …

Summary Future Challenges in Plant Pathology Plant infection is a complicated process. On
encountering a plant, pathogenic microorganisms must first adapt to life on the epiphytic …

Induced mechanisms are by definition imperceptible or less active in uninfected, unstressed,
or untreated plants, but can be activated by pathogen infection, stress, or chemical treatment …
