Diversity of Ralstonia solanacearum Infecting Eggplant in the Philippines.
ABSTRACT The diversity of Ralstonia solanacearum strains isolated from eggplant (Solanum melongena) grown in five provinces of the Philippine island group of Luzon was assessed using a recently described hierarchical system. All strains keyed to race 1, biovar 3 or 4. Phylotype-specific multiplex polymerase chain reaction (PCR) indicated that, like most other strains of Asian origin, all the st...
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 کاملEvolutionary dynamics of Ralstonia solanacearum.
We investigated the genetic diversity, extent of recombination, natural selection, and population divergence of Ralstonia solanacearum samples obtained from sources worldwide. This plant pathogen causes bacterial wilt in many crops and constitutes a serious threat to agricultural production due to its very wide host range and aggressiveness. Five housekeeping genes, dispersed around the chromos...
متن کاملCryo-electron microscopy three-dimensional structure of the jumbo phage ΦRSL1 infecting the phytopathogen Ralstonia solanacearum.
ϕRSL1 jumbo phage belongs to a new class of viruses within the Myoviridae family. Here, we report its three-dimensional structure determined by electron cryo microscopy. The icosahedral capsid, the tail helical portion, and the complete tail appendage were reconstructed separately to resolutions of 9 Å, 9 Å, and 28 Å, respectively. The head is rather complex and formed by at least five differen...
متن کاملGenomic diversity of large-plaque-forming podoviruses infecting the phytopathogen Ralstonia solanacearum.
The genome organization, gene structure, and host range of five podoviruses that infect Ralstonia solanacearum, the causative agent of bacterial wilt disease were characterized. The phages fell into two distinctive groups based on the genome position of the RNA polymerase gene (i.e., T7-type and ϕKMV-type). One-step growth experiments revealed that ϕRSB2 (a T7-like phage) lysed host cells more ...
