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:This SuperSeries is composed of the following subset Series: GSE33657: Expression analysis of Ralstonia solanacearum strain GMI1000 at 20°C and 28°C in rich medium (CPG) and in planta GSE33661: Expression analysis of Ralstonia solanacearum strain UW551 at 20°C and 28°C in rich medium (CPG) and in planta Refer to individual Series
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
Project description:We found the Type III effector protein RipAB could suppress multiple plant immune responses and is important for the virulence of bacterial wilt pathogen Ralstonia solanacearum.
