A bacterial acetyltransferase triggers immunity in Arabidopsis thaliana independent of hypersensitive response [PDF]

Scientific Reports, 2017
Type-III secreted effectors (T3Es) play critical roles during bacterial pathogenesis in plants. Plant recognition of certain T3Es can trigger defence, often accompanied by macroscopic cell death, termed the hypersensitive response (HR).

Characterization of novel bacteriophages for biocontrol of bacterial blight in leek caused by Pseudomonas syringae pv. porri [PDF]

Frontiers in Microbiology, 2016
Pseudomonas syringae pv. porri, the causative agent of bacterial blight in leek (Allium porrum), is increasingly frequent causing problems in leek cultivation. Because of the current lack of control measures, novel bacteriophages were isolated to control

Three Novel Bacteriophages for the Biocontrol of Pseudomonas syringae pv. actinidiae on Artificially Contaminated Kiwifruit Leaves [PDF]

Pathogens
This study compared the efficacy of three individual lytic phages, PSA_LMAPSA-2T (PSA-2T), PSA_LMAPSA-6F (PSA-6F) and PSA_LMAPSA-7F (PSA-7F) and four phage cocktails (dual and triple combinations) in inactivating Pseudomonas syringae pv.

Effector loss drives adaptation of Pseudomonas syringae pv. actinidiae biovar 3 to Actinidia arguta. [PDF]

PLoS Pathog, 2022
A pandemic isolate ofPseudomonas syringaepv.actinidiaebiovar 3 (Psa3) has devastated kiwifruit orchards growing cultivars ofActinidia chinensis. In contrast,A.arguta(kiwiberry) is not a host of Psa3. Resistance is mediated via effector-triggered immunity, as demonstrated by induction of the hypersensitive response in infectedA.argutaleaves, observed by

Genome, Proteome and Structure of a T7-Like Bacteriophage of the Kiwifruit Canker Phytopathogen Pseudomonas Syringae pv. Actinidiae [PDF]

Viruses, 2015
Pseudomonas syringae pv. actinidiae is an economically significant pathogen responsible for severe bacterial canker of kiwifruit (Actinidia sp.). Bacteriophages infecting this phytopathogen have potential as biocontrol agents as part of an integrated ...

Pseudomonas syringae pv. actinidiae: Ecology, Infection Dynamics and Disease Epidemiology. [PDF]

Microb Ecol, 2020
Since 2008, the kiwifruit industry has been devastated by a pandemic outbreak of Pseudomonas syringae pv. actinidiae (Psa), the causal agent of bacterial canker. This disease has become the most significant limiting factor in kiwifruit production. Psa colonizes different organs of the host plant, causing a specific symptomatology on each of them.

Plant Signals Anticipate the Induction of the Type III Secretion System in Pseudomonas syringae pv. actinidiae, Facilitating Efficient Temperature-Dependent Effector Translocation. [PDF]

Microbiol Spectr, 2022
Disease resistance in plants depends on a molecular dialogue with microbes that involves many known chemical effectors, but the time course of the interaction and the influence of the environment are largely unknown.

Distinct phenotypic behaviours within a clonal population of Pseudomonas syringae pv. actinidiae. [PDF]

PLoS ONE, 2022
Bacterial canker of the kiwifruit caused by the etiological agent Pseudomonas syringae pv. actinidiae is the most severe disease in kiwifruit production. Since 2008 a hypervirulent Psa biovar 3 has spread rapidly worldwide.

TaqMan qPCR assays improve Pseudomonas syringae pv. actinidiae biovar 3 and P. viridiflava (PG07) detection within the Pseudomonas sp. community of kiwifruit [PDF]

Phytopathologia Mediterranea, 2023
Kiwifruit is inhabited by a heterogeneous community of bacteria belonging to the Pseudomonas syringae species complex (Pssc). Only a few of its members, such as the specialist Pseudomonas syringae pv.

Identification and Characterization of Innate Immunity in Actinidia melanandra in Response to Pseudomonas syringae pv. actinidiae. [PDF]

Plant Cell Environ
ABSTRACT Pseudomonas syringae pv. actinidiae biovar 3 (Psa3) has decimated kiwifruit orchards growing susceptible kiwifruit Actinidia chinensis varieties. Effector loss has occurred recently in Psa3 isolates from resistant kiwifruit germplasm, resulting in strains capable of partially overcoming resistance present in kiwiberry vines (Actinidia arguta ...
