Ralstonia solanacearum needs motility for invasive virulence on tomato.
Ralstonia solanacearum, a widely distributed and economically important plant pathogen, invades the roots of diverse plant hosts from the soil and aggressively colonizes the xylem vessels, causing a lethal wilting known as bacterial wilt disease. By examining bacteria from the xylem vessels of infected plants, we found that R. solanacearum is essentially nonmotile in planta, although it can be ...
متن کاملComplete Genome Sequence of Ralstonia solanacearum FJAT-91, a High-Virulence Pathogen of Tomato Wilt
Ralstonia solanacearum FJAT-91, which displays higher virulence toward plants belonging to the family Solanaceae, was isolated from a wilted tomato plant vessel in Fujian province, southeast China. Here, we report the complete genome sequence of R. solanacearum FJAT-91 using long-read single-molecule PacBio sequencing technology. The genome comprises a 3,873,214-bp circular chromosome and a 2,0...
متن کاملEvaluation of Resistance to Ralstonia solanacearum in Tomato Genetic Resources at Seedling Stage
Bacterial wilt of tomatoes caused by Ralstonia solanacearum is a devastating disease that limits the production of tomato in Korea. The best way to control this disease is using genetically resistant tomato plant. The resistance degree to R. solanacearum was evaluated for 285 tomato accessions conserved in the National Agrobiodiversity Center of Rural Development Administration. These accession...
متن کاملRalstonia solanacearum encounters an oxidative environment during tomato infection.
Ralstonia solanacearum genes that are induced during tomato infection suggested that this pathogen encounters reactive oxygen species (ROS) during bacterial wilt pathogenesis. The genomes of R. solanacearum contain multiple redundant ROS-scavenging enzymes, indirect evidence that this pathogen experiences intense oxidative stress during its life cycle. Over 9% of the bacterium's plant-induced g...
متن کاملThe Virulence Factors of the Bacterial Wilt Pathogen Ralstonia solanacearum
One of the most important virulence factors is a heterogeneous polymer of N-acetylated extracellular polysaccharide I (EPS I) [8]. EPS I-deficient mutants are nearly avirulent and do not colonize plant xylem vessels as efficient as wild type [4,9]. It has been suggested that EPS I directly causes wilting by physically blocking the vascular system and thereby alters water movement [8]. It has al...
