Expression analysis of Ralstonia solanacearum strain UW551 at 20°C and 28°C in rich medium (CPG) and in planta

ABSTRACT: 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.

Expression analysis of Ralstonia solanacearum strain GMI1000 at 20°C and 28°C in rich medium (CPG) and in planta

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.

Expression data from Ralstonia solanacearum-inoculated tomato stem

Project description:Bacterial wilt caused by Ralstonia solanacearum is a lethal, soil-borne disease of tomato. Control of the disease with chemicals and crop rotation is insufficient, because the pathogen is particularly well adapted for surviving in the soil and rhizosphere. Therefore, cultivar resistance is the most effective means for controlling bacterial wilt, but the molecular mechanisms of resistance responses remain unclear. We used microarrays to obtain the characteristics of the gene expression changes that are induced by R. solanacearum infection in resistant cultivar LS-89 and susceptible cultivar Ponderosa. Seedlings of LS-89 and Ponderosa at the five to six leaf-stage were inoculated on their stems just above the cotyledon by cutting to one-third the stem depth with a knife, adding a drop of bacterial suspension (1e+6 cfu/ml of R. solanacearum strain 8107S) or distilled water to the opening, and then clipping the wound site to avoid bending. Inoculated plants were grown in a growth chamber at 30ÂºC under 30,000 lux light intensity for 12 h a day. At 1dpi, stems were sampled by dissecting 5 mm long sections from 5 mm below the inoculation site. For each hybridization, RNA from 15 plants was used. Three biological replicates of microarray analysis were performed.

Arabidopsis Col-5 challenged with Ralstonia solanacearum BCCF401

Project description:Arabidopsis plants were challenged with Ralstonia solanacearum isolate BCCF401 and expression profiles investigated during early and late wilt symptom development. Keywords: Disease state analysis A direct comparison was performed. Two replicate biological experiments were performed and two technical replicates with dye swap were included in each biological replicate.

Expression data from Arabidopsis thaliana Col-0 challenged with Ralstonia solanacearum race 4 (roots)

Project description:Bacterial wilt caused by Ralstonia solanacearum is a serious seed/soil borne disease that causes severe yield and quality losses in many plants. In order to understand the change in genome expression of inculated plants, microarray analysis were performed. Twenty one days old roots of Arabidopsis Col-0 were inoculated with Ralstonia solanacearum race 4 @ 10^9 & 10^8 cfu/ml in different plants, distil water were mock inoculated, after five days plants were taken for RNA extraction and hybridization on Affymetrix microarrays. Plants were incubated in growth chamber for disease development, temperature and humidity were maintained as per plant requirement for both treated and control plants.
