Bacillus thuringiensis toxins: an overview of their biocidal activity
Bacillus thuringiensis (Bt) is a Gram positive, spore-forming bacterium that synthesizes parasporal crystalline inclusions containing Cry and Cyt proteins, some of which are toxic against a wide range of insect orders, ... -
Biología de plásmidos y dinámica génica en el complejo Pseudomonas syringae
La mayoría de las cepas de Pseudomonas syringae posee uno o más plásmidos nativos tipo PFP, que suelen albergar genes adaptativos y que facilitan el intercambio de los mismos entre poblaciones bacterianas. P. syringae pv. ... -
Changes in race-specific virulence in Pseudomonas syringae pv. phaseolicola are associated with a chimeric transposable element and rare deletion events in a plasmid-borne pathogenicity island
Virulence for bean and soybean is determined by effector genes in a plasmid-borne pathogenicity island (PAI) in race 7 strain 1449B of Pseudomonas syringae pv. phaseolicola. One of the effector genes, avrPphF, confers ... -
Characterisation of the mgo operon in Pseudomonas syringae pv. syringae UMAF0158 that is required for mangotoxin production
Background: Mangotoxin is an antimetabolite toxin that is produced by strains of Pseudomonas syringae pv. syringae; mangotoxin-producing strains are primarily isolated from mango tissues with symptoms of bacterial ... -
Coping with environmental eukaryotes; identification of Pseudomonas syringae genes during the interaction with alternative hosts or predators
Understanding the molecular mechanisms underpinning the ecological success of plant pathogens is critical to develop strategies for controlling diseases and protecting crops. Recent observations have shown that plant ... -
Detection by multiplex PCR and characterization of nontoxigenic strains of Pseudomonas syringae pv. phaseolicola from different places in Spain. Short communication
(Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria (INIA), 2006) Artículo / ArtikuluaEl control eficiente de la grasa de la judía causada por Pseudomonas syringae pv. phaseolicola se basa principalmente en la utilización de semilla libre del patógeno. La detección del patógeno en semilla se efectúa mediante ... -
Draft genome sequence of Bacillus thuringiensis serovar tolworthi strain Na205-3, an isolate toxic for Helicoverpa armigera
We report here the complete annotated 6,510,053-bp draft genome sequence of Bacillus thuringiensis serovar tolworthi strain Na205-3, which is toxic for Helicoverpa armigera. This strain potentially contains nine insecticidal ... -
Draft genome sequences of two bacillus thuringiensis strains and characterization of a putative 41.9-kDa insecticidal toxin
In this work, we report the genome sequencing of two Bacillus thuringiensis strains using Illumina next-generation sequencing technology (NGS). Strain Hu4-2, toxic to many lepidopteran pest species and to some mosquitoes, ... -
Expression of the gene for resistance to phaseolotoxin (argK) depends on the activity of genes phtABC in Pseudomonas syringae pv. Phaseolicola
The bacterium Pseudomonas syringae pv. phaseolicola produces phaseolotoxin in a temperature dependent manner, being optimally produced between 18 degrees C and 20 degrees C, while no detectable amounts are present above ... -
Fate of a Pseudomonas savastanoi pv. savastanoi type III secretion system mutant in olive plants (Olea europaea L.)
Pseudomonas savastanoi pv. savastanoi strain NCPPB 3335 is a model bacterial pathogen for studying the molecular basis of disease production in woody hosts. We report the sequencing of the hrpS-to-hrpZ region of NCPPB 3335, ... -
Four genes essential for recombination define GInts, a new type of mobile genomic island widespread in bacteria
Integrases are a family of tyrosine recombinases that are highly abundant in bacterial genomes, actively disseminating adaptive characters such as pathogenicity determinants and antibiotics resistance. Using comparative ... -
Functional characterization of the gene cluster from Pseudomonas syringae pv. phaseolicola NPS3121 involved in synthesis of phaseolotoxin
Pseudomonas syringae pv. phaseolicola is the causal agent of halo blight disease of beans (Phaseolus vulgaris L.), which is characterized by water-soaked lesions surrounded by a chlorotic halo resulting from the action of ... -
Genes ptz and idi, coding for cytokinin biosynthesis enzymes, are essential for tumorigenesis and in planta growth by P. syringae pv. savastanoi NCPPB 3335
The phytopathogenic bacterium Pseudomonas syringae pv. savastanoi elicits aerial tumors on olive plants and is also able to synthesize large amounts of auxins and cytokinins. The auxin indoleacetic acid was shown to be ... -
Global genomic analysis of Pseudomonas savastanoi pv. savastanoi plasmids
Pseudomonas savastanoi pv. savastanoi strains harbor native plasmids belonging to the pPT23A plasmid family (PFPs) which are detected in all pathovars of the related species Pseudomonas syringae examined and contribute to ... -
Host range determinants of Pseudomonas savastanoi pathovars of woody hosts revealed by comparative genomics and cross-pathogenicity tests
The study of host range determinants within the Pseudomonas syringae complex is gaining renewed attention due to its widespread distribution in non-agricultural environments, evidence of large variability in intra-pathovar ... -
Identification of a pathogenicity island, which contains genes for virulence and avirulence, on a large native plasmid in the bean pathogen Pseudomonas syringae pathovar phaseolicola
The 154-kb plasmid was cured from race 7 strain 1449B of the phytopathogen Pseudomonas syringae pv. phaseolicola (Pph). Cured strains lost virulence toward bean, causing the hypersensitive reaction in previously ... -
The influence of the accessory genome on bacterial pathogen evolution
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. Molecular ... -
Knots untie: molecular determinants involved in knot formation Induced by Pseudomonas savastanoi in woody hosts
