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.

葡萄中的冠胆病是由带有致瘤性（Ti）质粒的葡萄球菌的致病性菌株引起的。阿非致病性菌株的VAR03-1 R.葡萄，已经从苗木的葡萄根中分离且显示作为生物控制剂，以冠瘿病。即使将其与病原体以1：1比例同时接种，也可观察到其抑制疾病的作用。这里，我们提出的完整基因组数据R.葡萄VAR03-1，通过测序组装读取由两个PacBio和Illumina的技术与注释获得。该基因组序列可有助于研究该细菌菌株的生物防治活性以及根定殖能力的分子基础。
