The results demonstrate that this screen can be used successfully to isolate genes that are induced in planta, including many novel genes potentially involved in pathogenesis, and several genes with unknown function that may encode novel virulence factors. Expand
The Pseudomonas syringae type III effector AvrRpt2 promotes virulence independently of RIN4, a predicted virulence target in Arabidopsis thaliana.
The results indicate that the virulence activity of AvrRpt2 in A. thaliana is likely to rely on the modification of host susceptibility factors other than, or in addition to, RIN4. Expand
Mutations in the Pseudomonas syringae avrRpt2 gene that dissociate its virulence and avirulence activities lead to decreased efficiency in AvrRpt2-induced disappearance of RIN4.
An alteration in kinetics of RIN4 disappearance triggered by the C-terminal deletion mutants may provide the mechanistic basis for the uncoupling of the avirulence and virulence activities of avrRpt2. Expand
The Pseudomonas syringae avrRpt2 gene contributes to virulence on tomato.
It is shown that a mutant derivative of JL1065 that carries a disruption in avrRpt2 is impaired in its ability to cause disease on tomato (Lycopersicon esculentum), indicating that avr rpt2 also acts as a virulence gene in its native strain on a natural host. Expand
Moonlighting Function of Phytochelatin Synthase1 in Extracellular Defense against Fungal Pathogens1[OPEN]
A role for PCS in disease resistance against plant pathogenic fungi is described and this enzyme is revealed to be a moonlighting protein important for plant responses to both biotic and abiotic stresses. Expand
Arabidopsis phytochelatin synthase 1, but not phytochelatin synthesis, functions in extracellular defense against multiple fungal pathogens
A hitherto uncharacterized role for PCS in disease resistance against plant pathogenic fungi is described and this enzyme is revealed to be a moonlighting protein important for plant responses to both biotic and abiotic stresses. Expand
