Project description:Chickpea (Cicer arietinum) is the third largest legume grown worldwide and are prone to drought and various pathogen infections. These stresses often occur concurrently in the field conditions. Previous studies in other plant species indicated that plant senses concurrently occurring stresses as new state of stress however, the molecular events in response to that is largely unknown. In the present study, we studied the transcriptome changes in chickpea plants exposed to combination of drought stress and a potential wilt pathogen, Ralstonia solanacearum by microarray analysis. Chickpea plants were exposed to short duration individual drought (SD-drought, soil field capacity, FC-35%), long duration individual drought (LD-drought, FC-30%), short duration individual pathogen stress (SD-pathogen = 2 days pathogen infection), long duration individual pathogen stress (LD-pathogen = 4 days of infection) and short duration and long duration combined stress, SD-combined = 2 days of pathogen infection with progressive drought (FC-40% to FC- 35%), LD combined = 4 days of pathogen infection with progressive drought (FC-35% to 30%).Transcriptome analysis for the leaf samples from above treatment were done by microarray analysis using Agilent ChickpeaGXP_8X60K chip. Result indicated presence of specific molecular events and also some common but tailored events in response to combined stress. Global transcriptional analysis in chickpea leaves exposed to individual and combined drought stress and Ralstonia solanacearum infection.

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.

Project description:Alternative splicing (AS) is a critical post-transcriptional regulatory mechanism in eukaryotes. While infection with Ralstonia solanacearum GMI1000 significantly alters plant AS patterns, the underlying molecular mechanisms remain unclear. Herein, we investigate the effects of GMI1000 Type III secretion system (T3SS) effector proteins on AS in the tomato cultivar Heinz 1706. RNA sequencing (RNA-seq) confirmed genome-wide AS changes induced by the T3SS in tomato, in-cluding 1386 differential alternative splicing events in 1023 differentially alternatively spliced genes, many of which are associated with plant defense. Seven nucleus-localized Type III effec-tors(T3Es) were transiently expressed in an RLPK splicing reporter system transgenic tobacco, identifying RipP2 as an effector that modulates AS levels. Sequence analysis, protein-protein in-teraction assays, and AlphaFold2 structural predictions revealed that RipP2 interacts with the tomato splicing factor SR34a.Furthermore, RipP2 acetylates a conserved lysine at position 132 within the SWQDLKD motif of SR34a, regulating its splicing pattern in defense-related genes and modulating plant immunity. This study elucidates how the "Rip-SR34a module" influences plant immune responses by regulating the alternative splicing of immune-related genes, providing new insights into the molecular mechanisms of pathogen-plant interactions, particularly in splicing regulation.

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.
