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

BMC 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

Deciphering the Key Players of the Bacterial Microbiota Associated with Aerial Crown Gall Tumors on Rhododendron: Insights into the Gallobiome

Phytobiomes Journal
Tumorigenic agrobacteria are widespread plant pathogens causing crown gall and cane gall diseases in various agricultural crops. These pathogens genetically transform the host plant and thus form an ecological niche (galls) in which specific metabolites (

Spatial distribution of Cynips quercusfolii (Hymenoptera: Cynipidae) galls on leaves and within the crowns of oak trees

European Journal of Entomology, 2013
The factors that affect oviposition and consequently spatial distribution of the galls of many gall makers are poorly understood. Knowledge of these factors could result in a better understanding of the mechanisms that initiate and regulate the ...

Crown galls

Glasnik zaštite bilja, 1999
TUMOR VRATA KORIJENA- Tumorske izrasline na biljkama uočene su još sredinom prošlog stoljeća, ali je tek 1907. godine uspjela izolacija patogene bakterija Agrobacterium radiobacter pv. tumefaciens (sin. Agrobacterium tumefaciens) iz njih. S izoliranom bakterijom izvršena je infekcija zdravih biljaka i na njima su se razbili tumori, što je dokazalo da ...

Crown gall tumors inCentaurium

Biologia Plantarum, 1985
Agrobacterium tumefaciens C58M (a nopaline strain) was used for induction of crown gall tumors inCentaurium umbellatum Gilib. The formation of tumors is very rare. After elimination of bacteria the tumor tissues grow in the light on R3B medium without growth regulators. They are positive in nopaline synthase.

Prevention of plant crown gall tumor development by the anti-malarial artesunate of Artemisia annua

Journal für Kulturpflanzen, 2009
The antimalarial drug artesunate, a sesquiterpene trioxane lactone derivative of artemisinin from Artemisia annua L., is known for its extraordinary inhibitory effects on plasmodia and trematodes and also for suppressing the proliferation of human tumor ...

Studies on Crown Gall

Japanese Journal of Phytopathology, 1972
The present paper deals with the morphogenesis of crown gall, with special regard to the differentiation of polarity.The outer morphology of the gall expressed various shapes by the autonomous cell proliferation. The shape and external apperance of the gall was more or less specific for the kind of host plants and the rate of daily growth reached to ca.

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

The 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 ...

Tartrate Utilization Genes Promote Growth of Agrobacterium spp. on Grapevine

Molecular Plant-Microbe Interactions, 1998
Crown gall on grapevine is mainly caused by Agrobacterium vitis, which metabolizes tartrate. Competition experiments between a tartrate-utilizing strain and its non-utilizing derivative showed that tartrate utilization confers a selective advantage on ...
