Project description:Investigation of whole genome gene expression level changes in the bacterial wilt pathogen Ralstonia solanacearum, strain GMI1000 at 20°C and 28°C in culture and in planta. The tropical strain GMI1000 cannot wilt tomato plants at 20°C although it can cause full-blown disease at 28°C. A 16 array study using total RNA recovered from the following: 8 separate cultures of Ralstonia solanacearum strain GMI1000 grown in rich medium-CPG (4 grown at 20°C and 4 grown at 28°C) 8 separate in planta samples of Ralstonia solanacearum strain GMI1000 harvested from diseased tomato plants cv. BonnyBest (4 recovered from plants grown at 20°C and 4 from plants grown at 28°C) Each array (4-plex format) measures the expression level of 5061 genes from Ralstonia solanacearum strain GMI1000 with 2 to 6, 40-70 mer probes per gene, with two-fold technical redundancy. The arrays also contain probes for intergenic regions with no technical replicates.

Project description:Investigation of whole genome gene expression level changes in the bacterial wilt pathogen Ralstonia solanacearum, strain UW551 at 20°C and 28°C in culture and in planta. The temperatel strain UW551 can wilt and cause full-blown disease on tomato plants at 28°C as well as at 20°C. A 16 array study using total RNA recovered from the following: 8 separate cultures of Ralstonia solanacearum strain UW551 grown in rich medium-CPG (4 grown at 20°C and 4 grown at 28°C) 8 separate in planta samples of Ralstonia solanacearum strain UW551 harvested from diseased tomato plants cv. BonnyBest (4 recovered from plants grown at 20°C and 4 from plants grown at 28°C) Each array (4-plex format) measures the expression level of 4318 genes from Ralstonia solanacearum strain UW551 with 2 to 6, 40-70 mer probes per gene, with two-fold technical redundancy. The arrays also contain probes for intergenic regions with no technical replicates.

Project description:Ralstonia solancearum causes bacterial wilt disease on diverse plant hosts. R. solanacearum cells enter a host from soil or infested water through the roots, then multiply and spread in the water-transporting xylem vessels. Despite the low nutrient content of xylem sap, R. solanacearum grows extremely well inside the host, using denitrification to respire in this hypoxic environment. R. solanacearum growth in planta also depends on the successful deployment of protein effectors into host cells using a Type III Secretion System (T3SS). The T3SS is absolutely required for R. solanacearum virulence, but it is metabolically costly and can trigger host defenses. Thus, the pathogen’s success depends on optimized regulation of the T3SS. We found that a byproduct of denitrification, the toxic free-radical nitric oxide (NO), positively regulates the R. solanacearum T3SS both in vitro and in planta. Using chemical treatments and R. solanacearum mutants with altered NO levels, we show that the expression of a key T3SS regulator is induced by NO in culture. Analyzing the transcriptome of R. solanacearum responding to varying levels of NO both in culture and in planta revealed that the T3SS and effectors were broadly upregulated with increasing levels of NO. This regulation was specific to the T3SS and was not shared by other stressors. Our results suggest that R. solanacearum experiences an NO-rich environment in the plant host and may use this NO as a signal to activate T3SS during infection.
