Molecular identification of the causal agent of bacterial wilt in tomato plants in southwestern Paraná

Semina: Ciências Agrárias
Bacterial wilt, caused by phytopathogenic species of the genus Ralstonia, is one of the main diseases affecting the tomato crop. The Ralstonia solanacearum species complex occurs as a result of variants being widely diverse in terms of adaptation to ...

Polyphenol Oxidase Activity Expression in Ralstonia solanacearum [PDF]

Applied and Environmental Microbiology, 2005
ABSTRACT Sequencing of the genome of Ralstonia solanacearum revealed several genes that putatively code for polyphenol oxidases (PPOs). To study the actual expression of these genes, we looked for and detected all kinds of PPO activities, including laccase, cresolase, and catechol oxidase activities, in ...

Molecular and Biological Characterization of Ralstonia Phage RsoM1USA, a New Species of P2virus, Isolated in the United States

Frontiers in Microbiology, 2019
The first Ralstonia-infecting bacteriophage from soil of the United States, designated RsoM1USA, was isolated from a tomato field in Florida. Electron microscopy revealed that phage RsoM1USA is member of the genus P2virus in the family Myoviridae with an

Plant Pathogenicity Phenotyping of Ralstonia solanacearum Strains

, 2017
In this chapter, we describe different methods for phenotyping strains or mutants of the bacterial wilt agent, Ralstonia solanacearum, on four different host plants: Arabidopsis thaliana, tomato (Solanum lycopersicum), tobacco (Nicotiana benthamiana), or Medicago truncatula.

Genome sequence of the plant pathogen Ralstonia solanacearum [PDF]

Nature, 2002
Ralstonia solanacearum is a devastating, soil-borne plant pathogen with a global distribution and an unusually wide host range. It is a model system for the dissection of molecular determinants governing pathogenicity. We present here the complete genome sequence and its analysis of strain GMI1000.

Suppression of DS1 phosphatidic acid phosphatase confirms resistance to Ralstonia solanacearum in Nicotiana benthamiana.

PLoS ONE, 2013
Nicotianabenthamiana is susceptible to Ralstonia solanacearum. To analyze molecular mechanisms for disease susceptibility, we screened a gene-silenced plant showing resistance to R. solanacearum, designated as DS1 (Disease suppression 1).

Plant‐Derived Melatonin Inhibits Bacterial Virulence via CpxA/R Two‐Component System

Advanced Science, EarlyView.
Plant‐derived melatonin is sensed by CpxAE48/T51, which inhibits the phosphorylation cascade transmission from CpxAH240 to CpxRD52, resulting in the inhibition of DNA‐binding capacity of CpxR and subsequent T3SS genes expression in Pst DC3000. ABSTRACT In defending against pathogens, plants deploy diverse secondary metabolites and signaling molecules ...

Novel plant inputs influencing Ralstonia solanacearum during infection [PDF]

Frontiers in Microbiology, 2013
Ralstonia solanacearum is a soil and water-borne pathogen that can infect a wide range of plants and cause the devastating bacterial wilt disease. To successfully colonize a host, R. solanacearum requires the type III secretion system (T3SS), which delivers bacterial effector proteins inside the plant cells.

Genetic Structure of Ralstonia solanacearum and Ralstonia pseudosolanacearum in Brazil [PDF]

Plant Disease, 2020
Bacterial wilt-causing Ralstonia threaten numerous crops throughout the world. We studied the population structure of 196 isolates of Ralstonia solanacearum and 39 isolates of Ralstonia pseudosolanacearum, which were collected from potato- and tomato-growing areas in 19 states of Brazil.
