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 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...
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 کاملSoil Amendments and Water Moisture on the Control of Tomato Bacterial Wilt Caused by Ralstonia Solanacearum
Bacterial wilt is one of the most severe tomato diseases worldwide and Ralstonia solanacearum is determined to be the pathogen responsible for its spread. Soil amendments such as calcium cyanamide and herb residues have both been proved to be high potential for tomato bacterial wilt control. Disinfection effect and heat generated during the decomposition processes of calcium cyanamide and herb ...
