Crown gall tumors collected from naturally infected plants of 7 grapevine varieties were analysed for the presence of opines. Eighty-five of the tested 90 samples contained known Agrobacterium vitis -induced opines. Octopine was the most common, it was found in 50 samples. Twentyeight crown galls contained nopaline and 8 were vitopine positive. There was only one tumor that contained two opines, nopaline and vitopine. Five samples were negative for the opines tested. The presence of A. vitis… Expand

Crown or root gall of grape is one of the most important bacterial diseases of vineyards in Turkey. Eighty-one vineyards in the Aegean Region were surveyed and 31 gall samples were collected betweenExpand
The Ecology of Agrobacterium vitis and Management of Crown Gall Disease in Vineyards.
Genetic and genomic analyses indicated that A. vitis is distinguishable from the members of the Agrobacterium genus and its transfer to the genus Allorhizobium was suggested, and it can be efficiently disseminated to distant geographical areas via international trade of propagation material. Expand
Characterization of Agrobacterium vitis isolates obtained from galled grapevine plants in Egypt
This is the first report on the identification of A. vitis in Egypt, and the ability to induce galls and necrosis on grapevine, and their reactions to standard biochemical and physiological tests is reported. Expand
Conventional PCR primers for the detection of grapevine pathogens disseminated by propagating material
Grapevine cultivation is endangered by several pathogens disseminated in latent form by propagating material. These pathogens include several viroids, viruses, phytoplasmas, bacteria and fungiExpand
Insight Into the Microbial Co-occurrence and Diversity of 73 Grapevine (Vitis vinifera) Crown Galls Collected Across the Northern Hemisphere
The technical and biological insights gained from this study will contribute to the understanding of complex interaction between the grapevine and its microbial community and may facilitate better management of CG disease in the future. Expand
Phenotypic and molecular characterization of Rhizobium vitis strains from vineyards in Turkey
Crown gall-affected grapevine samples were collected during 2009–2010 from major vineyards, located in different Turkish provinces. One hundred and three bacterial strains were obtained from 88Expand
Phenotypic and molecular characterization of Rhizobium vitis strains from vineyards in Turkey.
Nopaline and vitopine-types of Rhizobium vitis were detected for the first time in Turkey. Expand
PCR Identification of Pathogenic Agrobacteria Detected in Vineyards of Krasnodar Krai Based on the Type of Ti Plasmids
The obtained data indicate that crown gall of grapes in the vineyards of Krasnodar krai is caused by agrobacteria A. vitis, mainly of the octopine type. Expand
Isolation and characterization of Agrobacterium strains from grapevines in Bulgarian vineyards and wild grapes, V. vinifera ssp. silvestris
The strict correlation between the results from biochemical and virulence tests and PCR analysis suggests that the chosen PCR procedures can be used efficiently for direct PCR testing for the presence and tumorigenicity of A. vitis in grapevines. Expand
High-Quality Draft Genome Sequence of the Type Strain of Allorhizobium vitis, the Primary Causal Agent of Grapevine Crown Gall
A hybrid approach generated 50% fewer contigs and a 3-fold increase in the N50 value compared with the previous Illumina-only assembly of Allorhizobium vitis K309T, a phytopathogenic strain isolated from a grapevine in Australia. Expand


CROWN GALL OF GRAPE: Biology and Disease Management.
Control practices rely on the use of disease-resistant cultivars, cultural practices that minimize plant injury, and the production of pathogen-free vines, and promising future controls include employment of biological control agents and development of crown gall-resistant transgenic grapevines. Expand
Opines in crown gall tumours induced by biotype 3 isolates of Agrobacterium tumefaciens
Octopine, nopaline, agropine and vitopine were detected in healthy tissues of plants infected with the appropriate Agrobacterium isolates, indicating that these opines can selectively promote the colonization of the whole plant by agrobacteria. Expand
Diversity of opines and opine-catabolizing bacteria isolated from naturally occurring crown gall tumors
Several unusual opine catabolic combinations were identified, including isolates that catabolized a variety of opines but were nonpathogenic, and more variability was observed among isolates from field tumors on the remaining plant species. Expand
Types of resistance of grapevine varieties to isolates of Agrobacterium tumefaciens biotype 3
Eight grapevine varieties representing four susceptibility patterns were infected with octopine-,nopaline- and vitopine-inducing isolates of Agrobacterium tumefaciens and showed three different types of resistance. Expand
Chemistry and biochemistry of opines, chemical mediators of parasitism
Abstract Opines consititute a class of substances that are characteristic of crown gall and hairy root, two proliferative plant diseases caused by Agrobacterium tumefaciens and A. rhizogenes. AboutExpand
Ti Plasmids from AgrobacteriumCharacterize Rootstock Clones That Initiated a Spread of Crown Gall Disease in Mediterranean Countries
The integrated physiological and molecular analyses of 30 Agrobacterium isolates obtained from crown gall tumors and of several reference strains suggest that the causal agent of crown gall disease in rose plants is transmitted via rootstock material. Expand
Opines and Opine-Like Molecules Involved in Plant-Rhizobiaceae Interactions
It was understood only years later that the production of opines by the crown gall cells provided the pathogen with a selective growth advantage, and the fundamental role of opine in the Agrobacterium-plant interaction was rationalized by the originators of “ the opine concept” and “the genetic colonization theory”.
