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.

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 30ºC 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.

Project description:Rhizoctonia solani is an economically important soil-borne necrotrophic fungal pathogen, with a broad host range and for which little effective resistance exists in crop plants. Arabidopsis is resistant to the R. solani AG8 isolate but susceptible to R. solani AG2-1. Affymetrix microarray analysis was performed to determine genes that are affected in common and specifically by AG8 and AG2-1.

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:Ralstonia solanacerum causes bacterial wilt disease on many important host crops, including tomato and potato. 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 and oxygen 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 successful mitigation of oxidative stress produced by both the bacterium and the host. We found that proteins encoded by norA and hmpX that are predicted to interact with nitric oxide (NO) and protect against cellular damage caused by NO. Reducing NO toxicity is especially important for Rs that generates NO via denitrifying respiration in planta, and encounters NO produced by plants as a defense and signaling molecule. By analyzing transcriptomes of mutants lacking these genes, we found that iron, sulfur, and nitrogen metabolism genes were consistently upregulated in mutants missing these genes. Our transcriptomic analysis suggests R. solanacearum mutants lacking norA and hmpX suffer oxidative stress from an increase in cellular toxicity caused by NO that leads to damage of iron, sulfur, and nitrogen metabolic proteins. Our results suggest that NorA and HmpX, contribute to oxidative stress mitigation in denitrifying cultures.

Project description:Ralstonia solanacearum, recognized as a pervasive plant pathogen causing lethal wilt disease in over 450 plant species worldwide, represents a substantial threat to economically vital crops including tomato, chili, and eggplant. Within R. solanacearum, pehR serves as a transcriptional regulator, forming part of the pehSR two-component regulatory system. This system governs the production of polygalacturonase (PG), a crucial extracellular enzyme involved in plant cell wall degradation and bacterial wilt development. Our study focuses on a disruption mutant of the pehR gene from the local isolate R. solanacearum F1C1, obtained from Tezpur, Assam. Utilizing RNA-seq, we examine the gene expression profiles of R. solanacearum F1C1 under pehR regulation. Differential expression analysis between wild type and pehR mutants reveals a set of genes directly influenced by pehR. This comprehensive gene expression analysis provides insights into the system-level responses orchestrated by the pehR regulator in pathogenicity and virulence development. Moreover, it sheds light on the broader regulatory network controlled by pehR and its underlying molecular mechanisms. Our work also underscores the identification of key target genes regulated by pehR within R. solanacearum F1C1, offering a deeper understanding of its role in bacterial pathogenicity. Ultimately, unraveling the complete pehR regulome holds promise for elucidating the regulatory dynamics driving the pathogenic behavior of R. solanacearum F1C1.

Arabidopsis is resistant to the R. solani AG8 isolate but susceptible to R. solani AG2-1. Affymetrix microarray analysis was performed to determine genes that are affected in common and specifically by AG8 and AG2-1. 3 biological samples were taken from 3 treatments: non-infected control, R. solani AG8 infection and R. solani AG2-1 infection.

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.
