Genome Sequencing of Ralstonia solanacearum FQY_4 from bacterial wilt Nursery. Ralstonia pseudosolanacearum FQY_4

Genome Sequencing of Ralstonia solanacearum FQY_4 will provide us such an example to explore how the geographical and pathogenic variation strains emerged and evolved and how they acquired new traits, such as resistance or pathogenicity. Ralstonia solanacearum, the causal agent of globally dispersed bacterial wilt disease, infected an unusually wide range of plant species, and the harm is particularly serious in such economical important crops as tomatoes, tobacco and potatoes etc. R. solanacearum strain FQY_4 was isolated from a bacterial wilt Nursery, which is used for evaluating crops resistance to Ralstonia in tobacco and potatoes breeding in China. The R. solanacearum nursery was established in Guizhou province, southwest of China, in 1986 and nominated as a national bacterial wilt Nursery for breeding crops resistance to Ralstonia, mainly for tobacco cultivars in 1997.

青枯雷尔氏菌（Ralstonia solanacearum）FQY_4菌株的基因组测序，将为我们提供一个研究范例，用以解析地理与致病特性变异菌株的产生、演化机制，以及它们获取抗性或致病性等新性状的途径。青枯雷尔氏菌是全球广泛分布的细菌性萎蔫病致病菌，其寄主范围异乎寻常地广泛，尤其对番茄、烟草、马铃薯等经济重要作物造成极为严重的危害。青枯雷尔氏菌FQY_4菌株分离自中国用于烟草和马铃薯育种的青枯病抗性评价圃。该青枯病抗性评价圃于1986年建于中国西南部贵州省，并于1997年被认定为国家级青枯病抗性育种专用圃，主要服务于烟草品种选育。
