Transcriptome Analysis of Quantitative Resistance-Specific Response upon Ralstonia solanacearum Infection in Tomato

Bacterial wilt, caused by the soil-borne bacterium Ralstonia solanacearum, is a lethal disease of tomato, but the molecular mechanisms of the host resistance responses to R. solanacearum remain unclear. In this study, we report the first work describing the transcriptome of cultivar resistance and susceptible tomato cultivar after inoculation with R. solanacearum. To elucidate the characteristi...

Evaluation of Resistance to Ralstonia solanacearum in Tomato Genetic Resources at Seedling Stage

Bacterial wilt of tomatoes caused by Ralstonia solanacearum is a devastating disease that limits the production of tomato in Korea. The best way to control this disease is using genetically resistant tomato plant. The resistance degree to R. solanacearum was evaluated for 285 tomato accessions conserved in the National Agrobiodiversity Center of Rural Development Administration. These accession...

Induction of Systemic Resistance in Tomato against Ralstonia solanacearum by Pseudomonas fluorescens

The biological control agent Pseudomonas fluorescens was used against the bacterial wilt causing Ralstonia solanacearum. The present investigation focuses on the role of defense related enzymes in imparting resistance in tomato against R. solanacearum. A total of ten rhizobacterial isolates were screened against R. solanacearum, of which three isolates (Pf3, Pf5 & Pf8) showed a maximum inhibiti...

Rutin-Mediated Priming of Plant Resistance to Three Bacterial Pathogens Initiating the Early SA Signal Pathway

Flavonoids are ubiquitous in the plant kingdom and have many diverse functions, including UV protection, auxin transport inhibition, allelopathy, flower coloring and insect resistance. Here we show that rutin, a proud member of the flavonoid family, could be functional as an activator to improve plant disease resistances. Three plant species pretreated with 2 mM rutin were found to enhance resi...
