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).

Transcription profiling of Fusarium head blight resistance in Sumai-3 and two susceptible NILs

Project description:Microarray gene expression analysis were performed to identify genes responding to Fusarium graminearum inoculation and genes that show a differential regulation between the resistant c.v. Sumai-3 and the susceptible near isogenic lines. Sumai-3 is a Chinese wheat cultivar, the most commonly used source of resistance to Fusarium head blight (FHB) disease. NIL-3 and NIL-4 are near isogenic lines susceptible to FHB and are derived from a cross between Sumai-3 and Chuan980, a susceptible wheat cultivar, followed by seven generations of marker assisted backcrossing with the recurrent parent Sumai-3 and selection for FHB susceptibility in each generation by artificial inoculation with F. graminearum. A combination of DNA markers including simple sequence repeats (SSRs) and amplified fragment length polymorphisms (AFLPs) were used to screen for DNA polymorphisms between Sumai-3 and its susceptible NILs. Polymorphic markers were mapped using a mapping population. The analysis indicated 7 polymorphisms between the susceptible NILs and the resistant Sumai-3. The analysis indicated that NIL-3 differs from Sumai-3 at chromosome 3BS and NIL-4 differs from Sumai-3 at chromosome 2AL region.

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

Project description: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. The equivalent experiment is TA20 at PLEXdb.] FHB resistant and susceptible plants 48 an 96 hours after treatment with Fusarium graminearum strain Butte 86

Response to Fusarium in near-isogenic lines harboring resistance QTLs Fhb1 and Qfhs.ifa-5A

Project description:Resistance mechanisms of wheat to Fusarium graminearum are still poorly understood. Multiple reports have investigated transcriptomic differences between resistant and susceptible genotypes. To investigate the genetic determinants underlying the two major contributor QTL Fhb1 and Qfhs.ifa-5A, we generated a set of near-isogenic lines, that we have used for transcriptomic studies using the Affymetrix wheat GeneChip®: 4 near-isogenic lines (BC5F2) derived from a cross of CM82036 and cv Remus (susceptible recurrent parent) and the resistant parent CM82036 have been inoculated with Fusarium spore suspension or water as control at anthesis. Samples have been taken at 3 timepoints 8, 24 and 72 hours after inoculation. Five wheat heads per condition were pooled into one sample, that has been used for RNA preparation. Including 3 replicates a total of 90 microarrays have been hybridized. Our results identify a wide variety of genes (631 transcripts) that are differentially regulated for Fusarium graminearum in all genotypes after 72 h and 339 genes that are upregulated only in lines without Qfhs.ifa.5A. Few genes were found differentially regulated for Fusarium and QTL. Many interesting candidates emerge from the set of QTL-specific genes that are constitutively expressed when comparing water-treated samples. ****[PLEXdb(http://www.plexdb.org) has submitted this series at GEO on behalf of the original contributor, Wolfgang Schweiger.

Transcriptome analysis of rice in relation to infection with rice tungro spherical virus (RTSV)

Project description:Near-isogenic lines TW16-4 and TW16-69 were developed from the cross between TN1 (recurrent parent susceptible to RTSV) and Utri Merah (donor parent resistant to RTSV). TW16-4 is susceptible to RTSV, whereas TW16-69 is resistant to RTSV based on a serolog. Keywords: time course, virus infection, disease response

RNA-seq of coding RNA of wheat heads from 3, 6, 12, 24, 36, and 48 hours after inoculation of fungal pathogen Fusarium graminearum or mock inoculation

Project description:Near isogenic wheat lines(NILs), differing in the presence of both or none of the FHB-resistance QTL Fhb1 and Qfhs.ifa-5A, have been sequenced using Illumina HiSeq2000 under disease pressure (3, 6, 12, 24, 36, 48 hai) as well as with mock-inoculation, to discern transcriptional differences induced by Fusarium graminearum. The NILs are BC5F2 lines generated from the Mexican Spring wheat line CM-82036, the resistance QTL donor line, as recurrent background and the susceptible German Spring wheat line Remus as the donor of the susceptible QTL alleles.

Expression data in wheat (T. aestivum L.) near isogenic lines in response to powdery mildew infection

Project description:We used two wheat genotypes, the susceptible wheat cultivar ‘8866 ’(S) and its near isogenic line with single powdery mildew resistance gene ‘pm30’ (R), to investigate gene expression changes in response to powdery mildew infection by using Wheat Genome Array wheat young leveas of near isogenic lines before or 12 hours after powdery mildew infection were selected for RNA extraction and hybridization on Affymetrix microarrays.The leaf samples were harvested from three independent biological replicates, and the leaves without inoculation were regarded as control.
