Abstract Background Tomato plant leaves can be wilted by the presence of various species soil-residing bacteria, especially Ralstonia solanacearum . Soil solarization has proven to an environment-friendly method for disease management in crops. Therefore, this study aimed evaluate as effective and non-chemical way control R. population farm soil cultivated with tomato plants. The variety UC 82 ...

Microbial pathogens infect host cells by delivering virulence factors (effectors) that interfere with defenses. In plants, intracellular nucleotide-binding/leucine-rich repeat receptors (NLRs) detect specific effector interference and trigger immunity by an unknown mechanism. The Arabidopsis-interacting NLR pair, RRS1-R with RPS4, confers resistance to different pathogens, including Ralstonia s...

Ralstonia mannitolilytica is a gram negative soil bacterium. Ralstonia infection though rare, has become the emerging nosocomial pathogens in hospital settings. Various clinical manifestations had been described as well as the mode of transmission. Despite its low virulence factor, it is able to survive under harsh condition and this may potentially cause significant morbidity and mortality esp...

Soil acidity is one of the main constraints to crop production worldwide. In Ethiopia, problem soil has been increasing. Currently, more than 40% cultivated land in country a pH < 5.5. Recently, bacterial wilt (caused by Ralstonia solanacearum) become serious problem, reaching epidemic levels some major potato growing districts country. However, it currently unknown if current outbreak assoc...

Ralstonia solanacearum species complex (RSSC) is the main pathogen causing bacterial wilt disease in tomatoes. This study applied colony polymerase chain reaction (PCR) technique to rapidly screen and select RSSC strains from isolated bacteria of diseased method directly used colonies on Petri plate as templates amplify with RSSC’s specific multiplex primers. The results showed that Vietnamese ...

Xanthomonas translucens is the causal agent of bacterial leaf streak, the most common bacterial disease of wheat and barley. To cause disease, most xanthomonads depend on a highly conserved type III secretion system, which translocates type III effectors into host plant cells. Mutagenesis of the conserved type III secretion gene hrcT confirmed that the X. translucens type III secretion system i...

The reproductive potentials of Heterodera glycines (mixture of races 3 and 4 and unidentified races) and a tobacco cyst nematode Globodera tabacum solanacearum were studied in the field. The experiments involved four cultivars of soybean Glycine max and four cultivars of Nicotiana tabacum. The reproductive potential of the H. glycines population was high on Essex and Lee 74 soybean but low on F...
