Identification of open reading frames unique to a select agent: Ralstonia solanacearum race 3 biovar 2.
An 8x draft genome was obtained and annotated for Ralstonia solanacearum race 3 biovar 2 (R3B2) strain UW551, a United States Department of Agriculture Select Agent isolated from geranium. The draft UW551 genome consisted of 80,169 reads resulting in 582 contigs containing 5,925,491 base pairs, with an average 64.5% GC content. Annotation revealed a predicted 4,454 protein coding open reading f...
متن کاملDraft Genome Sequences of Ralstonia solanacearum Race 3 Biovar 2 Strains with Different Temperature Adaptations
Ralstonia solanacearum race 3 biovar 2 (R3bv2) causes brown rot of potato in countries with temperate climates. Here, we report two draft genome sequences of R. solanacearum R3bv2 NCPPB909 and CFIA906 with different temperature adaptations. Analysis of these genome sequences will provide detailed insight on virulence, functionality, and plant/pest interactions of this widely distributed and reg...
متن کاملTropical strains of Ralstonia solanacearum Outcompete race 3 biovar 2 strains at lowland tropical temperatures.
Bacterial wilt, caused by members of the heterogenous Ralstonia solanacearum species complex, is an economically important vascular disease affecting many crops. Human activity has widely disseminated R. solanacearum strains, increasing their global agricultural impact. However, tropical highland race 3 biovar 2 (R3bv2) strains do not cause disease in tropical lowlands, even though they are vir...
متن کاملComparative Transcriptome Analysis Reveals Cool Virulence Factors of Ralstonia solanacearum Race 3 Biovar 2
While most strains of the plant pathogenic bacterium Ralstonia solanacearum are tropical, the race 3 biovar 2 (R3bv2) subgroup attacks plants in cooler climates. To identify mechanisms underlying this trait, we compared the transcriptional profiles of R. solanacearum R3bv2 strain UW551 and tropical strain GMI1000 at 20°C and 28°C, both in culture and during tomato pathogenesis. 4.2% of the ORFs...
متن کاملRalstonia solanacearum Race 3 Biovar 2 Causes Tropical Losses and Temperate Anxieties
Introduction Bacterial wilts caused by Ralstonia solanacearum (Smith 1986) Yabuuchi et al. 1996 (formerly called Pseudomonas solanacearum) have long been a scourge of tropical agriculture because the pathogen is very widely distributed and has an unusually broad host range (7,13). Moreover, because R. solanacearum is a soilborne pathogen and host resistance is limited, bacterial wilt is very di...
