Abstract
ABSTRACTRalstonia solanacearum is a globally distributed plant pathogen that causes bacterial wilt diseases of many crop hosts, threatening both sustenance farming and industrial agriculture. Here, we present closed genome sequences for the R. solanacearum type strain, K60, and the cool-tolerant potato brown rot strain R. solanacearum UW551, a highly regulated U.S. select agent pathogen.
Highlights
Ralstonia solanacearum is a globally distributed plant pathogen that causes bacterial wilt diseases of many crop hosts, threatening both sustenance farming and industrial agriculture
The R. solanacearum type strain is K60, which belongs to phylotype II, sequevar 7
And for regulatory purposes known as R. solanacearum race 3, biovar 2 (R3bv2), strains in this subgroup mostly fall into phylotype II, sequevar 1 [3]
Summary
Ralstonia solanacearum is a globally distributed plant pathogen that causes bacterial wilt diseases of many crop hosts, threatening both sustenance farming and industrial agriculture. The R. solanacearum type strain is K60, which belongs to phylotype II, sequevar 7. K60, known as UW25, was isolated in 1953 from a Marglobe tomato in Raleigh, North Carolina, USA [4], and has been used extensively for bacterial wilt research [5, 6]. Similar sequevar 7 strains currently cause bacterial wilt of tomato, tobacco, pepper, and ornamentals in the southeastern United States [6,7,8,9].
