Transcriptome analysis of a wheat NIL pair carrying FHB resistant and susceptible alleles

ABSTRACT: In this study, we used the Affymetrix wheat GeneChip to examine the transcript accumulation in a near-isogenic line pair carrying resistant and susceptible alleles at the wheat Fhb1 locus. The objectives of this study were: (1) to identify the overall response in wheat to F. graminearum infection; (2) to identify key genes involved in FHB resistance/susceptibility pathways in wheat; (3) to compare the transcript profiles of wheat and barley during F. graminearum infection; and (4) to examine the relationship between transcript accumulation, disease severity, fungal biomass and trichothecene accumulation in wheat. ****[PLEXdb(http://www.plexdb.org) has submitted this series at GEO on behalf of the original contributor, Seungho Cho.

Fusarium head blight (FHB), caused primarily by Fusarium graminearum, decreases grain yield and quality in wheat and barley. Disease severity, deoxynivalenol (DON), fungal biomass, and transcript accumulation were examined in a wheat near-isogenic line pair carrying either the resistant or susceptible allele for the chromosome 3BS FHB-resistance quantitative trait locus (Fhb1). Fhb1 restricts spread of disease symptoms but does not provide resistance to initial infection or initial DON accumulat ...[more]

Transcription profiling of wheat development

Project description:The analysis of gene expression during wheat development:; Gene expression measurements were carried out on a developmental tissue; series for wild-type wheat (cv. Chinese Spring) using the Affymetrix; Wheat GeneChip. Thirteen tissues at defined developmental stages were; chosen to match the barley (cv.

Transcriptomic analysis of F. graminearum disease response in near-isogenic resistant and susceptible hexaploid wheat lines

Project description:Fusarium graminearum causes Fusarium head blight (FHB), which represents one of the major wheat diseases worldwide, determining reduction in grain quality, yield and the accumulation of mycotoxins. To mine the molecular response associated to the wheat 2DL FHB resistance quantitative trait locus (QTL), derived from the cultivar Wuhan-1, and to identify candidate genes implicated in such resistance, a comprehensive transcriptomic analysis of the early response to F. graminearum infection at 3 days post inoculation of spikelet and rachis was performed with the RNA-Seq and miRNA-Seq techniques. The analyses were conducted on two Near Isogenic Lines (NILs) differing for the presence of the 2DL QTL (2-2618, resistant 2DL+ and 2-2890, susceptible null).

Fumarylacetoacetate hydrolase targeted by a Fusarium graminearum effector positively regulates wheat FHB resistance and yield and promotes heading

Project description:Fusarium head blight (FHB), caused by Fusarium graminearum is a devastating disease that affects global wheat production. F. graminearum encodes many effector proteins; however, its virulence mechanisms are poorly understood. In this study, we identified a secretory effector candidate protein (FgEC10) that is essential for the virulence of F. graminearum and suppresses the basal immune response. FgEC10 interacted strongly with wheat fumarylacetoacetate hydrolase (TaFAH) and accelerated its degradation via the 26S proteasome pathway. In addition, we showed that TaFAH interacted with TaPSMD, an important component of the 26S proteasome and that FgEC10 enhanced the interaction between TaFAH and TaPSMD. RNA silencing or overexpression of TaFAH in wheat plants showed that TaFAH positively regulated wheat FHB resistance, heading period, and grain yield. Transcriptomic analysis revealed that TaFAH promoted the expression of genes associated with disease resistance and the heading period. Metabolomic analysis revealed that overexpression of TaFAH increased the levels of several amino acids that inhibited F. graminearum growth and enhanced wheat resistance to FHB. Collectively, our study reveals a novel pathogenic mechanism and provides a valuable genetic resource for improving FHB resistance and grain yield in wheat.

Dual RNA-sequencing of Fusarium Head Blight resistance in winter wheat

Project description:In this study, we used dual RNA-sequencing to profile FHB-resistant AC Emerson, FHB-moderately AC Morley, and FHB-susceptible CDC Falcon winter wheat cultivars prior to and in response to Fusarium graminearum at 7 days post inoculation. Differential expression analyses revealed distinct defense responses between resistant and susceptible wheat cultivars including increased mechanical defense through lignin biosynthesis and increased deoxynivalenol (DON) detoxification through UDP-glycosyltransferase activity in resistant cultivars. Further, differential expression analysis in F. graminearum challenging these distinct cultivars revealed changes genes involved in trichothecene mycotoxin biosynthesis.
