We cloned the rpoN (ntrA and glnF) gene encoding sigma(54) from the phytopathogen Pseudomonas syringae pv. maculicola strain ES4326. The P. syringae ES4326 rpoN gene complemented Pseudomonas aeruginosa, Escherichia coli, and Klebsiella aerogenes rpoN mutants for a variety of rpoN mutant phenotypes, including the inability to utilize nitrate as sole nitrogen source. DNA sequence analysis of the ...
Lectin-like bacteriotoxic proteins, identified in several plant-associated bacteria, are able to selectively kill closely related species, including several phytopathogens, such as Pseudomonas syringae and Xanthomonas species, but so far their mode of action remains unrevealed. The crystal structure of LlpABW, the prototype lectin-like bacteriocin from Pseudomonas putida, reveals an architectur...
Pseudomonas putida KT2440 is an efficient colonizer of the rhizosphere of plants of agronomical and basic interest. We have demonstrated that KT2440 can protect the model plant Arabidopsis thaliana against infection by the phytopathogen Pseudomonas syringae pv. tomato DC3000. P. putida extracellular haem-peroxidase (PP2561) was found to be important for competitive colonization and essential fo...
ABSTRACT The role of bacterially produced salicylic acid (SA) in the induction of systemic resistance in plants by rhizobacteria is far from clear. The strong SA producer Pseudomonas fluorescens WCS374r induces resistance in radish but not in Arabidopsis thaliana, whereas application of SA leads to induction of resistance in both plant species. In this study, we compared P. fluorescens WCS374r ...
The genome sequence of more than 100 Pseudomonas syringae strains has been sequenced to date; however only few of them have been fully assembled, including P. syringae pv. syringae B728a. Different strains of pv. syringae cause different diseases and have different host specificities; so, UMAF0158 is a P. syringae pv. syringae strain related to B728a but instead of being a bean pathogen it caus...
Three different cosmid clones were isolated from a genomic library of the tomato pathogen Pseudomonas syringae pv. tomato, which, when introduced into the soybean pathogen P. syringae pv. glycinea, caused a defensive hypersensitive response (HR) in certain soybean cultivars. Each clone was distinguished by the specific cultivars that reacted hypersensitively and by the intensity of the HR elici...
Phytobacteria are potent threat to sustainable chilli (Capsicum annuum L.) production all over the world. In past, bacterial infections were reported in plantations of Pakistan but data is still scanty and sporadic. Therefore, this study was planned evaluate germplasm resistance against local putative isolates. Chilli infected disease samples collected from Mianwali, Taxila, Chakwal, Islamabad ...
SUMMARY The last decade has witnessed steady progress in deciphering the molecular basis of plant disease resistance and pathogen virulence. Although contributions have been made using many different plant and pathogen species, studies of the interactions between Arabidopsis thaliana and Pseudomonas syringae have yielded a particularly significant body of information. The present review focuses...
