Broad‐range antagonistic rhizobacteria Pseudomonas fluorescens and Serratia plymuthica suppress Agrobacterium crown gall tumours on tomato plants
Aim:  To examine the biocontrol activity of broad‐range antagonists Serratia plymuthica IC1270, Pseudomonas fluorescens Q8r1‐96 and P. fluorescens B‐4117 against tumourigenic strains of AgrobacteriumExpand
Inhibition of quorum‐sensing signals by essential oils
The role of quorum sensing is well known in microbial pathogenicity and antibiotic resistance, and the inhibition of QS signals reduces the problem of resistance and virulence. Expand
Novel pathogen-specific primers for the detection of "Agrobacterium vitis" and "Agrobacterium tumefaciens"
A wide range of agrob bacteria occurring on grapevine were detected and identified and results confirm that vitopine-type agrobacteria form a distinct group within the genus Agrobacterium. 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
Deep sequencing of the ancestral tobacco species Nicotiana tomentosiformis reveals multiple T-DNA inserts and a complex evolutionary history of natural transformation in the genus Nicotiana.
This analysis, together with that of Nicotiana glauca and otherNicotiana species, indicates multiple sequential insertions of cT-DNAs during the evolution of the genus Nicotsiana. Expand
Characterization of Agrobacterium tumefaciens strains isolated from grapevine
Characterization of these strains showed that 7 of the 18 strains carried A. tumefaciens nopaline strains, which induced octopine/agropine-, and two strains induced agropine producing tumors on grapevine and/or Kalanchoe tubiflora plants and reacted positively to virC-specific PCR primers. Expand
Nucleotide sequence, evolutionary origin and biological role of a rearranged cytokinin gene isolated from a wide host range biotype III Agrobacterium strain
The results provide further insight into the molecular basis of the host range differences between limited host range and wide host range biotype III Agrobacterium strains and show that the WHR cytokinin gene, although active, does not significantly contribute to tumour formation on the natural host of theWHR biotypes III strains, grapevine.

Optimization of conditions for regeneration and genetic transformation of rootstock- and scion grape varieties
Embryogenic calli have been produced from 19 of the 41 grapevine cultivars tested, including internationally grown and traditional Hungarian varieties, novel candidates, as well as rootstockExpand
