Ralstonia pseudosolanacearum Safni et al. 2014

Ralstonia pseudosolanacearum is a soil-borne bacterium. It is a vascular phytopathogen that infects host plants through the root system causing wilting disease that causes loss in a wide range of crops.^[1] R. pseudosolanacearum is Gram negative and was originally identified as Ralstonia solanacearum, however, in 2014 Safni et al. proposed a taxonomic revision of the Ralstonia solanacearum species complex to reclassify phylotype strains, including R. pseudosolanacearum (R. solanacearum Phylotypes I and III). ^[2]

R. pseudosolanacearum has been reported in a wide variety of crops including ornamental roses (Rosa sp.), tomatoes (Solanum lycopersicum), sweet peppers (Capsicum annum) and eggplant (Solanum melongena). ^[3] Recent studies have found significant differences in disease severity influenced by higher temperatures (28°C) indicating temperature may be a virulence factor upon host colonization. The same study also reported wound inoculation resulted in higher disease severity regardless of temperatures tested (20°C -vs- 28°C) in addition to the potential implications of latent infections. ^[3]
