Pathogenicity and virulence factors of Pseudomonas syringae

Journal of General Plant Pathology, 2013
In 1994, Oku reported that plant pathogens, mainly fungal pathogens, require three essential abilities to infect plants: to enter plants, to overcome host resistance, and to evoke disease. Because the infectious process of phytopathogenic bacteria differs from that of fungal pathogens, we have attempted to characterize pathogenic- ity, the ability of a

The plant microbiome: From ecological foundations to precision microbial engineering for sustainable agriculture

iMeta, EarlyView.
From ecological principles to precision engineering of plant microbiomes for sustainable agriculture. The plant holobiont integrates diverse microbial niches (including rhizosphere, endosphere, phyllosphere, seed, and aerial‐root mucilagesphere), host genetics (namely M genes), and host metabolites. Furthermore, molecular dialogues, including rhizobial

Debneyol decoded: A metabolic organizer powers broad‐spectrum plant defense

New Plant Protection, EarlyView.
Abstract A new Cell study by Wang et al. resolves the long‐elusive biosynthesis and regulation of debneyol, a fungicidal sesquiterpenoid phytoalexin in Solanaceae. The authors define the complete three‐step route from farnesyl pyrophosphate to debneyol and identify the small protein MCD1 as a metabolic organizer that assembles a multienzyme complex to ...

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.

Signal transduction schemes in Pseudomonas syringae

Computational and Structural Biotechnology Journal, 2020
To cope with their continually fluctuating surroundings, pathovars of the unicellular phytopathogen Pseudomonas syringae have developed rapid and sophisticated signalling networks to sense extracellular stimuli, which allow them to adjust their cellular composition to survive and cause diseases in host plants.

The epidemiology of the blackleg pathogen, Leptosphaeria maculans, impacts fungicide resistance management strategies

Pest Management Science, EarlyView.
Understanding how infection timing drives disease is essential for the development of fungicide resistance management strategies. For blackleg disease of canola, all infection timings can contribute to the following generation, therefore all fungicide applications have the ability to select for resistance.

In planta Transcriptome Analysis of Pseudomonas syringae

BIO-PROTOCOL, 2018
Profiling bacterial transcriptome in planta is challenging due to the low abundance of bacterial RNA in infected plant tissues. Here, we describe a protocol to profile transcriptome of a foliar bacterial pathogen, Pseudomonas syringae pv. tomato DC3000, in the leaves of Arabidopsis thaliana at an early stage of infection using RNA sequencing (RNA-Seq).

Alcoholic extracts of Russian sage (Salvia yangii) contain bioactive terpenoids with inhibitory activity against grapevine downy mildew (Plasmopara viticola)

Pest Management Science, EarlyView.
Alcoholic extracts from flowers, leaves, and shoots of Russian sage decreased downy mildew severity on grapevine leaf disks. Fractionation followed by metabolomic analysis revealed putative terpenoids as the main components of the active fractions. Specifically, 7‐methylrosmanol, 12‐O‐methylcarnosic acid, carnosic acid, and carnosol were identified as ...
