Antibacterial activity of mexican oregano essential oil (Lippia berlandieri) against the phytopathogenic bacterium Xanthomonas euvesicatoria

Tecnociencia Chihuahua, 2020
Xanthomonas euvesicatoria causes bacterial spot disease in leaves, roots, fruits and stems of pepper plants. Identification of this phytopathogen in jalapeno seeds from Delicias, Chihuahua, Mexico and diseased plants from New Mexico, USA, was ...

Navigating Host Immunity and Concurrent Ozone Stress: Strain‐Resolved Metagenomics Reveals Maintenance of Intraspecific Diversity and Genetic Variation in Xanthomonas on Pepper

Evolutionary Applications, Volume 18, Issue 1, January 2025.
ABSTRACT The evolving threat of new pathogen variants in the face of global environmental changes poses a risk to a sustainable crop production. Predicting and responding to how climate change affects plant‐pathosystems is challenging, as environment affects host–pathogen interactions from molecular to the community level, and with eco‐evolutionary ...

Decoding Plant–Pathogen Interactions: A Comprehensive Exploration of Effector–Plant Transcription Factor Dynamics

Molecular Plant Pathology, Volume 26, Issue 1, January 2025.
Pathogen effectors from fungi, oomycetes, bacteria and nematodes manipulate plant transcription factors through diverse strategies, including degradation, activity modulation, and subcellular relocalization. ABSTRACT In the coevolutionary process between plant pathogens and hosts, pathogen effectors, primarily proteinaceous, engage in interactions with

Report of the Scientific Committee of the Spanish Agency for Food Safety and Nutrition (AESAN) on the relationship between climate change and food security, and its impact on the nutritional status of the population

Food Risk Assess Europe, Volume 3, Issue 1, January 2025.
Abstract Food security is the way to quantify the degree of access the population has to nutritious and safe food at all times. It depends on several factors, including the availability and affordability of that food. This term should not be confused with food safety, which is understood to be the discipline, process or action that prevents food from ...

XopM, An FFAT Motif‐Containing Type III Effector Protein From Xanthomonas, Suppresses MTI Responses at the Plant Plasma Membrane

Molecular Plant Pathology, Volume 25, Issue 12, December 2024.
The Xanthomonas type III effector protein XopM mimics eukaryotic FFAT motifs to bind VAP at the host cell plasma membrane to indirectly interfere with membrane‐associated MAMP‐triggered immunity (MTI) responses. ABSTRACT Many gram‐negative pathogenic bacteria use type III effector proteins (T3Es) as essential virulence factors to suppress host immunity

Onion‐pathogenic Burkholderia species: Role and regulation of characterized virulence determinants

Plant Pathology, Volume 73, Issue 9, Page 2281-2297, December 2024.
Protein secretion systems and toxoflavin are well‐characterized virulence factors in onion‐pathogenic Burkholderia species. The tofIMR quorum‐sensing system and qsmR regulate multiple Burkholderia virulence factors. Abstract Members of the bacterial genus Burkholderia are a routine threat to onion production worldwide.

Phylogenomics of Xanthomonas field strains infecting pepper and tomato reveals diversity in effector repertoires and identifies determinants of host specificity

Frontiers in Microbiology, 2015
Bacterial spot disease of pepper and tomato is caused by four distinct Xanthomonas species and is a severely limiting factor on fruit yield in these crops.

Progress in Developing Bacterial Spot Resistance in Tomato

Agronomy, 2019
Bacterial spot (BS), caused by four species of Xanthomonas: X. euvesicatoria, X. vesicatoria, X. perforans and X. gardneri in tomato (Solanum lycopersicum L.) results in severe loss in yield and quality by defoliation and the appearance of lesions on ...

Interspecies Expression of an EF-HAND CALCIUM-BINDING PROTEIN in Xanthomonas perforans Leads to Reduced Virulence and Decreased Immune Evasion in Tomato Plants

Molecular Plant-Microbe Interactions
Many phytopathogenic bacteria require a type III secretion system (TTSS) to activate effector-triggered immunity (ETI). We identified a calcium-binding protein, EfhXXfa, in the citrus pathogen Xanthomonas citri subsp. aurantifolii that does not require a
