“…The extent of CG development correlates with the number of transformation events and plant vigour. Grapevines developing small CGs show no growth limitations (Ferreira et al 1992; Schroth et al 1988) and the grapevines of this study did also not display an obvious phenotype. Opines are unique compounds produced by CGs which can only be metabolized by bacteria expressing enzymes for opine uptake and degradation.…”

“…Allorhizobium vitis ( Rhizobiaceae ), former Agrobacterium vitis or Agrobacterium tumefaciens biovar 3, is the causal pathogen of grapevine crown galls (CGs) which hamper plant growth and yield (Ferreira et al 1992; Schroth et al 1988). Overall, the family Rhizobiaceae contains both virulent and non-virulent species (Bien et al 1990; Chandrasekaran et al 2019) and Rhizobiaceae are associated with different grapevine tissues (Burr and Katz 1983).…”

Young grapevines (Vitis vinifera) suffer and eventually can die from the crown gall (CG) disease caused by the plant pathogen Allorhizobium vitis (Rhizobiaceae). Virulent members of A. vitis harbour a tumor-inducing (Ti) plasmid and induce formation of crown galls (CGs) due to the oncogenes encoded on the transfer-DNA (T-DNA). Expression of oncogenes in transformed host cells induce unregulated cell proliferation, metabolic and physiological changes. The CG produces opines uncommon to plants, which provide an important nutrient source for A. vitis harbouring opine catabolism enzymes. CGs host a distinct bacterial community and the mechanisms establishing a CG-specific bacterial community are currently unknown. Thus, we were interested in whether genes homologous to those of the Ti-plasmid coexist in the genomes of the microbial species coexisting in CGs. We isolated eight bacterial strains from grapevine CGs, sequenced their genomes and tested their virulence and opine utilization ability in bioassays. In addition, the eight genome sequences were compared to 34 published bacterial genomes, including closely related plant associated bacteria not from CGs. Homologous genes for virulence and opine anabolism were only present in the virulent Rhizobiaceae. By contrast, homologs of the opine catabolism genes were present in all strains including the non-virulent members of the Rhizobiaceae and non-Rhizobiaceae. Gene neighbourhood and sequence identity of the opine degradation cluster of virulent and non-virulent strains together with the results of the opine utilization assay support the important role of opine utilization for co-colonization in CGs, thereby shaping the CG community.

“…Hem kanserli hem de sağlıklı kalemlerin denendiği çalışmalar arasında gözlerde uyanma, sürgün ve yaprak değerleri ile ilgili çok fazla veriye rastlanmamıştır. Fakat kanserli kalemlerde yapılan sıcak su uygulaması kanser gelişimini önemli derecede azalttığını (Bazzi et al, 1991) fakat tamamen önleyemediğini bildirmektedirler (Burr et al, 1997 (Schroth et al, 1988;Ferreira et al, 1992;Keller 2010;Saygılı ve ark., 2019) denilebilir.…”

Using hot water against agricultural pest and diseases is one of the physical management methods. The point to be noticed in the application is to determine the degree of temperature and the duration that the plant can withstand. The aim of this study is to determine the viability levels at the grapevine buds of both infected with Agrobacterium vitis and healthy grapevine cutting belonging to the Narince cv. after treated with hot water at different temperature degrees of 20, 45, 46, 48, 50, 52, 54, 55 and 56 °C for 30 minutes. Bud burst ratio of cancered plant propagating materials was occurred to be low (%65.8). In healthy plant propagating materials, while hot water treatments by 50 ºC encouraged renascensing in plant buds, it caused inclines in cancered plant propagating materials. Every 1 degree ºC increase after 50 ºC caused approximately %7.7 decrease in renascensing in plant buds in healthy plant propagating materials.
