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 کاملRalstonia solanacearum, a widespread bacterial plant pathogen in the post-genomic era.
UNLABELLED Ralstonia solanacearum is a soil-borne bacterium causing the widespread disease known as bacterial wilt. Ralstonia solanacearum is also the causal agent of Moko disease of banana and brown rot of potato. Since the last R. solanacearum pathogen profile was published 10 years ago, studies concerning this plant pathogen have taken a genomic and post-genomic direction. This was pioneered...
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 کاملOn the life of Ralstonia solanacearum, a destructive bacterial plant pathogen
Ralstonia solanacearum is a relevant and widespread phytopathogenic bacterium that causes a wilt disease with deadly effects on many economically important crops and ornamentals. It belongs to the β-proteobacteria and is considered a “species complex”. This soil and water borne bacterium enters the plant roots, multiplies through the xylem, collapses the host and returns to the environment. It ...
