| comparative effect of low temperature on virulence and twitching motility of ralstonia solanacearum strains present in florida. | abstract ralstonia solanacearum causes bacterial wilt on a wide range of plant hosts. most strains of r. solanacearum are nonpathogenic below 20°c; however, race 3 biovar 2 (r3b2) strains are classified as quarantine pathogens because of their ability to infect crops, cause disease, and survive in temperate climates. we have identified race 1 biovar 1 phylotype iib sequevar 4 strains present in florida which were able to infect and produce wilt symptoms on potato and tomato at 18°c. moreover t ... | 2011 | 21936660 |
| diversity among ralstonia solanacearum strains isolated from the southeastern united states. | this is the first comprehensive study of a collection of ralstonia solanacearum strains from the southeastern united states to be characterized based on biovar, pathogenicity, hypersensitive reaction on tobacco, and phylogenetic analyses of the egl sequence. rigorous phylogenetic analysis of the commonly used egl gene produced robust phylogenies that differed significantly from a neighbor-joining tree differed from and previously published phylogenies for r. solanacearum strains. these robust tr ... | 2012 | 22957819 |
