Crown gall disease in grapevine is caused by pathogenic strains of Rhizobium vitis with a tumor-inducing (Ti) plasmids. A nonpathogenic strain, VAR03-1 of R. vitis , has been isolated from the grapevine root of nursery stock and it was shown to act as a biological control agent to crown gall disease. Its disease-suppressive effect was observed even when it was coinoculated with the pathogen in a 1:1 ratio. Here, we present the complete genome data of R. vitis VAR03-1, assembled by sequencing reads obtained by both PacBio and Illumina technologies with annotation. This genome sequence could contribute to investigations of the molecular basis underlying the biocontrol activity as well as the root-colonization ability of this bacterial strain.[Formula: see text] Copyright © 2020 The Author(s).

Rhizobium vitis strain VAT03-9 (MAFF 211676) is a causal agent of crown gall disease in grapevine. It is one of the pathogenic strains of R. vitis isolated from graft unions of grapevine in Okayama Prefecture, Japan. Inoculation tests verified its virulence for gall formation on grapevine, tomato, and sunflower. It harbors tumor-inducing plasmid. Here, we present the complete genome sequence with annotation of R. vitis VAR03-9 obtained by assembling reads from PacBio and Illumina-sequencers. This genome sequence should be useful for the analyses of pathogenicity and evolutionary lineage of the pathogens of crown gall disease.[Formula: see text] Copyright © 2020 The Author(s).

Rhizobium ( Agrobacterium ) is one genus in the family Rhizobiaceae. Most of the species are epi- or endophytic bacteria which include tumorigenic or rhizogenic pathogens, root nodule bacteria, and commensal endosymbionts. Rhizobium vitis strain VAR06-30 is a commensal bacterium without pathogenicity which was isolated from a rootstock of grapevine in Japan. It also does not have antagonistic activity to the pathogenic strain of R. vitis . Here, we show the complete genome sequence data with annotation of R. vitis VAR06-30 which was analyzed by sequence reads obtained from both PacBio and Illumina platforms. This genome sequence would contribute to the understanding of evolutionary lineage and characteristics of Rhizobium commensal bacteria.[Formula: see text] Copyright © 2020 The Author(s).
