Genome sequence of the tobacco bacterial wilt pathogen Ralstonia solanacearum.
Ralstonia solanacearum is a causal agent of plant bacterial wilt with thousands of distinct strains in a heterogeneous species complex. Here we report the genome sequence of a phylotype IB strain, Y45, isolated from tobacco (Nicotiana tabacum) in China. Compared with the published genomes of eight strains which were isolated from other hosts and habitats, 794 specific genes and many rearrangeme...
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...
متن کاملChemotaxis is required for virulence and competitive fitness of the bacterial wilt pathogen Ralstonia solanacearum.
Ralstonia solanacearum, a soilborne plant pathogen of considerable economic importance, invades host plant roots from the soil. Qualitative and quantitative chemotaxis assays revealed that this bacterium is specifically attracted to diverse amino acids and organic acids, and especially to root exudates from the host plant tomato. Exudates from rice, a nonhost plant, were less attractive. Eight ...
متن کاملEpsR modulates production of extracellular polysaccharides in the bacterial wilt pathogen Ralstonia (Pseudomonas) solanacearum.
Ralstonia solanacearum is the causal agent of bacterial wilt of many agriculturally important crops. Exopolysaccharide synthesized by products of the epsI operon is the major virulence factor for R. solanacearum. Expression of epsI has been demonstrated to be under the control of several proteins, including several two-component regulators. Overexpression of EpsR was found previously to reduce ...
متن کاملRalstonia Solanacearum Species Complex and Bacterial Wilt Disease
The bacterium Ralstonia solanacearum is a widely accepted model organism for the study of pathogenicity in plants [1]. This soil-borne bacterium, which belongs to the betaproteobacteria, is responsible for bacterial wilt on more than 200 plant species from 50 botanical families, including important crops such as potato, tomato, eggplant, pepper, tobacco and banana. In fact, bacterial wilt is co...
