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:The aim of the project is to decipher the role of DNA methylation in the plant pathogenic bacteria Ralstonia solanacearum during host adaptation. As a first step, we present here the DNA methylation profile of the GMI1000 reference strain.
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.
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.
Project description:Bacterial wilt, caused by the soil-borne bacterium Ralstonia solanacearum, is a lethal disease of mulberry, but the molecular mechanisms of the host resistance responses to R. solanacearum remain unclear. In order to better understand molecular resistance mechanisms to R. solanacearum in mulberry, we set out to define the changes in gene expression of resistance and susceptible mulberry cultivars after inoculation with R. solanacearum. Susceptible cultivar YSD10, resistance cultivar KQ10 and YS283 were inoculation with R. solanacearum, mulberry root samples were collected at 1 dpi and non-treated control in all cultivars. Then we performed RNA-Seq analyses on all mulberry root samples using Illumina HiSeq 2000.
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.
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.
