Biological Control of Crown Gall on Peach and Cherry Rootstock Colt by Native Agrobacterium radiobacter Isolates
Crown gall caused by Agrobacterium tumefaciens is the major limiting factor in raising healthy stone fruit plants in nurseries. The incidence of crown gall varies from 4 to 97.5 per cent at different locations resulting in out right rejection of an average of 30 per cent stone fruit plants in nurseries. Agrobacterium radiobacter strain K-84 has been reported to provide nearly complete control o...
متن کاملPlant responses to Agrobacterium tumefaciens and crown gall development
Agrobacterium tumefaciens causes crown gall disease on various plant species by introducing its T-DNA into the genome. Therefore, Agrobacterium has been extensively studied both as a pathogen and an important biotechnological tool. The infection process involves the transfer of T-DNA and virulence proteins into the plant cell. At that time the gene expression patterns of host plants differ depe...
متن کاملIsolation of Agrobacterium Tumefaciens Strains from Crown Gall Disease on Imported Roses Plants in Qazvin Province
Cultivar of roses (Rosa spp.) has been grown in greenhouses in Qazvin region of Iran for local markets. Agrobacterium tumefaciens strains were isolated and identified from six different samples of roses plants imported from the Netherland to Iran. During August and September of 2012, nearly 2-5% of rose plants in two different greenhouses in the province of Qazvin were observed with crown gall ...

Crown gall disease caused by Agrobacterium tumefaciens is considered as the main bacterial disease of stone fruit rootstocks in Tunisia against which only prophylactic control measures are available. Therefore, twelve rhizobacterial strains and two reference antagonists Agrobacterium rhizogenes K84 and K1026 were investigated for their efficacy against the causal agent of the disease in vitro, ...
متن کاملMechanisms of tumor induction in crown gall. I. Production and pathogenicity of spheroplasts of Agrobacterium tumefaciens.
The hypothesis that crown gall tumorigenesis requires the formation of spheroplasts was tested by comparing the tumorinducing ability of populations of both permanent and revertable spheroplasts of Agrobacterium tumefaciens with that of popula tions of the typical rod form of the bacterium. Permanent spheroplasts produced by serial transfers in medium containing 0.005 MD-methionine did not prod...
