Crown Gall

Crown gall is one of the most important bacterial diseases of grapevine worldwide and is especially debilitating on cultivars of Vitis vinifera. It is widespread, mainly in temperate areas, and especially in Mediterranean countries. Agrobacterium vitis is the predominant species that causes the disease, although A. tumefaciens is occasionally isolated from infected vines. Basically, the taxonomy of bacteria belonging to Agrobacterium genus has been determined relying on their phytopathogenic abilities. However, the loss or acquisition of the tumour-inducing (Ti) or root-inducing (Ri) plasmid could lead to a change of species status. Recently, on the basis of biochemical features, agrobacteria were divided into 3 biovars, but this classification did not correspond to the classification based on phytopathogenic abilities. Further studies, mostly based on ribosomal genes, confirmed that classification into biovars reflected phylogenetic relationships and, consequently, agrobacteria were classified into five species: A. radiobacter (biovar 1 strains), A. rhizogenes (biovar 2), A. vitis (biovar 3), A. rubi and A. larrymoorei. OMICS Group International is one of the leading Open Access Publishers which is publishing 700+ peer-reviewed journals with the support of 50,000+ editorial board members as editorial team and aimed to disseminate the scholarly knowledge to the scientific society. OMICS Group also organizing 3000+ International Scientific Conferences and events yearly all over the world with the support of 1000+ Scientific associations worldwide.
