The Arabidopsis thaliana JASMONATE INSENSITIVE 1 gene is required for suppression of salicylic acid-dependent defenses during infection by Pseudomonas syringae.
Many plant pathogens suppress antimicrobial defenses using virulence factors that modulate endogenous host defenses. The Pseudomonas syringae phytotoxin coronatine (COR) is believed to promote virulence by acting as a jasmonate analog, because COR-insensitive 1 (coil) Arabidopsis thaliana and tomato mutants are impaired in jasmonate signaling and exhibit reduced susceptibility to P. syringae. T...
متن کاملبررسی اثر چند ژن بیماری زا در زندگی اپیفیتی (Pseudomonas syringae)
Pseudomonas syringae is a phytopathogenic bacterium with a wide host range. The biology of this bacterium consists of two phases. The first phase is the indication of disease on the host plant which generally appears in the form of necrosis on the aerial parts of plant (pathogenicity phase). The second phase is a rapid multiplication of bacteria on the aerial surface of the plant without inflic...
متن کاملGenome and Transcriptome Sequences of Pseudomonas syringae pv. syringae B301D-R
Strains of the plant pathogen Pseudomonas syringae are commonly found in the phylosphere and are able to infect a number of agriculturally important crops. Here, we report a high-quality draft genome sequence of Pseudomonas syringae pv. syringae B301D-R, isolated from pears, which is a model strain for phytotoxin research in P. syringae.

متن کاملCloning and expression of genes required for coronamic Acid (2-ethyl-1-aminocyclopropane 1-carboxylic Acid), an intermediate in the biosynthesis of the phytotoxin coronatine.
Coronamic acid (CMA; 2-ethyl-1-aminocyclopropane 1-carboxylic acid) is an intermediate in the biosynthesis of coronatine (COR), a chlorosis-inducing phytotoxin produced by Pseudomonas syringae pv. glycinea PG4180. Tn5 mutagenesis and substrate feeding studies were previously used to characterize regions of the COR biosynthetic gene cluster required for synthesis of coronafacic acid and CMA, whi...
