The mbo operon is specific and essential for biosynthesis of mangotoxin in Pseudomonas syringae. [PDF]

PLoS ONE, 2012
Mangotoxin is an antimetabolite toxin produced by certain Pseudomonas syringae pv. syringae strains. This toxin is an oligopeptide that inhibits ornithine N-acetyl transferase, a key enzyme in the biosynthesis of ornithine and arginine.

The influence of the accessory genome on bacterial pathogen evolution [PDF]

, 2011
Bacterial pathogens exhibit significant variation in their genomic content of virulence factors. This reflects the abundance of strategies pathogens evolved to infect host organisms by suppressing host immunity.

Dual Disruption of the Immune Cytokine Spätzle Facilitates Fungal Infection of Diverse Insect Hosts

Advanced Science, EarlyView.
The Toll pathway is essential for insect defense against fungal pathogens. This works reports that fungal parasites employ two divergent virulent effectors to target the Toll receptor ligand Spätzle: a metalloprotease degrading it and a hairpin‐like effector hijacking it to block signal transduction. This dual strategy enables the fungus to kill a wide

Reversal of an immunity associated plant cell death program by the growth regulator auxin [PDF]

, 2007
One form of plant immunity against pathogens involves a rapid host programmed cell death at the site of infection accompanied by resistance, termed the hypersensitive response (HR).

Diversity of pathogenic Pseudomonas isolated from citrus in Tunisia

AMB Express, 2020
The damages observed in Tunisian citrus orchards have prompted studies on the Pseudomonas spp. responsible for blast and black pit. Prospective orchards between 2015 and 2017 showed that the diseases rapidly spread geographically and to new cultivars.

Effect of beneficial microbes applications on nutritional profiles of organic tomatoes revealed by LC‐MS‐qTOF metabolomics

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND The use of microorganisms and biostimulants is increasingly supported in agriculture because of their advantageous impact on plant disease management, growth enhancement and the synthesis of beneficial bioactive secondary metabolites (SMs). Tomato (Solanum lycopersicum) is an important crop and is consumed worldwide because it is an

The Diversity of Lipopeptides in the Pseudomonas syringae Complex Parallels Phylogeny and Sheds Light on Structural Diversification during Evolutionary History

Microbiology Spectrum, 2022
Pseudomonas spp. colonize diverse aquatic and terrestrial habitats and produce a wide variety of secondary metabolites, including lipopeptides. However, previous studies have often examined a limited number of lipopeptide-producing strains. In this study,

Plant defense strategies: The dual armor of disease resistance and tolerance

New Plant Protection, EarlyView.
Plants employ dual strategies against pathogens: Resistance limits invasion via immune responses, whereas tolerance mitigates damage to sustain growth—together enhancing survival under infections. Abstract Pathogen infections pose a significant threat to plant health, global food security, and ecosystems.
