Effect of volatile compounds produced by endophytic bacteria on virulence traits of grapevine crown gall pathogen, Agrobacterium tumefaciens

open access: yesScientific Reports, 2022
The volatile organic compounds (VOCs) produced by endophytic bacteria have a significant role in the control of phytopathogens. In this research, the VOCs produced by endophytic bacteria including Serratia sp. Ba10, Pantoea sp.

Patentable Formula Based on Essential Oils with a Protective Effect Against Rhizobium Vitis

open access: yesBulletin of University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca: Horticulture, 2023
The crown gall of grapevines is an economic importance bacteriosis caused by Rhizobium vitis strains. Five essential oils (EO’s) were tested against the autochthonous 2btm strain of R.

Use of Chitosan to Control Crown Gall Disease

open access: yesPlant Pathology Journal, 2015
A B S T R A C T The antibacterial activity of chitosan solution against Agrobacterium tumifaciens was investigated in this study. The in vitro antibacterial effect of chitosan against A. tumifaciens was affected by chitosan concentrations, pH value, concentration of acetic acid used to dissolve chitosan and incubation time.

Expression of a crown gall biological control phenotype in an avirulent strain of Agrobacterium vitis by addition of the trifolitoxin production and resistance genes

open access: yesBMC Biotechnology, 2002
Background Agrobacterium vitis is a causal agent of crown-gall disease. Trifolitoxin (TFX) is a peptide antibiotic active only against members of a specific group of α-proteobacteria that includes Agrobacterium and its close relatives. The ability of TFX

Isolation and Characterization of Pseudomonas sp. YU44 as Microbial Pesticide for Crown Gall Disease in Grapevine and Rose

open access: yesMicrobiology Research
Crown gall disease, caused by soil-borne bacterial pathogens, such as Allorhizobium vitis, poses a significant threat to grapevine cultivation in Japan, particularly under environmental conditions exacerbated by climate change. Effective chemical control

Relationship of Siderophore-Mediated Iron Assimilation to Virulence in Crown Gall Disease [PDF]

open access: yesJournal of Bacteriology, 1981
Three classes of mutants defective in the biosynthesis of the siderophore agrobactin were isolated from Agrobacterium tumefaciens A217 after N -methyl- N ′-nitro- N -nitrosoguanidine mutagenesis.

The Ti Plasmid‐Encoded VirJ Functions as a Lysyl‐Phosphatidylglycerol Hydrolase in Agrobacterium tumefaciens

open access: yesMolecular Microbiology, EarlyView.
We identify the long‐known virulence factor VirJ as a lysyl‐phosphatidylglycerol (L‐PG) hydrolase. Like the chromosomally encoded virulence factor AcvB, it prevents excessive accumulation of L‐PG in the membrane, thereby maintaining efficient T‐DNA transfer via the Type IV secretion system (T4SS) in Agrobacterium tumefaciens.

Phage Display Derived Antibodies Against Antimicrobial Peptide FsPDF2 Reveal Stress Response in European Beech

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Plant defensins (PDFs) are cysteine‐rich antimicrobial peptides (AMPs) that are important components of plant immunity. They occur constitutively in various plant tissues but are also upregulated upon stress. Therefore, these molecules are of great interest as markers for the diagnosis of early forest stress response in plants at the molecular

Profiling of Disease-Related Metabolites in Grapevine Internode Tissues Infected with Agrobacterium vitis

open access: yesThe Plant Pathology Journal, 2016
Green shoot cuttings of 10 different grapevine species were inoculated with Agrobacterium vitis to find disease-related metabolites in the grapevine. Crown galls formed 60 days after inoculation varied in gall severity (GS) evaluated by gall incidence ...
