Characterization of the Wheat-Psathyrostachys huashania 2Ns/2D Substitution Line H139: A Novel Germplasm with Enhanced Resistance to Wheat Take-all

Project description:Take-all is a devastating soil-borne disease that affects wheat production. The continuous generation of disease-resistance germplasm is an important aspect of the management of this pathogen. In this study, we characterized the wheat-Psathyrostachys huashania Keng-derived progeny H139 that exhibits significantly improved resistance to wheat take-all disease compared with its susceptible parent 7182. GISH) and mc-FISH analyses revealed that H139 is a stable wheat-P. huashania disomic substitution line lacking wheat chromosome 2D.EST-STS marker and Wheat Axiom 660K Genotyping Array analysis further revealed that H139 was a novel wheat-P. huashania 2Ns/2D substitution line, and that the P. huashania 2Ns chromosome shares high sequence similarity to wheat chromosome 2D. These results indicate that H139, with its enhanced wheat take-all disease resistance and desirable agronomic traits, provides valuable genetic resources for wheat chromosome engineering breeding.

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

Rhizoctonia solani AG8 infection of wheat seedling roots

Project description:Rhizoctonia solani is a nectrotrophic fungal pathogen that causes billions of dollars of damage to agriculture worldwide and infects a broad host range including wheat, rice, potato and legumes. In this study we identify wheat genes that are differentially expressed in response to the R. solani isolate, AG8-1, using microarray technology. A significant number of wheat genes identified in this screen were involved in ROS production and redox regulation. Levels of ROS species were increased in wheat root tissue following R. solani infection as determined by NBT, DAB and titanium sulphate measurements/stainings. Pathogen/ROS related genes from R. solani were also tested for expression patterns upon wheat infection. TmpL, a R. solani gene homologous to a gene associated with ROS regulation in Alternaria brassicicola, and OAH, a R. solani gene homologous to oxaloacetate acetylhydrolase which has been shown to produce oxalic acid in Sclerotinia sclerotiorum, were highly induced in R.solani when infecting wheat. We speculate that the wheat germin-like protein (GLP) is induced to inactivate the oxalic acid that is produced by the R. solani OAH.

Wheat transcriptomic responses to long-term feeding by wheat curl mites

Project description:The economic importance of wheat and its contribution to human and livestock diets has been already demonstrated. However, wheat production is impacted by pests that induce yield reductions. Among these pests, wheat curl mite (WCM, Aceria tosichella Keifer) impacts wheat all around the world. WCM are tiny pests that feed within the whorl of developing leaves and prevent the leaves from unfurling by causing leaves curling. The curling of the leaves provides a protective niche for the WCM. Additionally, WCM are also the vector of serious viruses in wheat. Little is known regarding the impact of the WCM on wheat transcriptome, and to date, only one article has been published describing the wheat transcriptomic changes after 1 day of WCM feeding. To better understand the wheat transcriptome variation after long-term feeding by WCM (10 days post infestation (dpi)), we used an RNA-seq approach. We collected leaves uninfested and infested with WCR from two wheat cultivars: Byrd (WCM resistant) and Settler CL (WCM susceptible) at 10 dpi. Our transcriptomic analysis revealed the common and specific transcriptomic variations in WCM resistant and susceptible wheat cultivars, chromosome specific location of the differentially expressed genes, and also identified the gene functions and pathways involved in WCM resistance. Collectively, our study provides important insights on wheat defense mechanisms against WCM after long-term feeding.

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.]

Expression data from wheat cultivars

Project description:To identify genes involved in susceptibility, genechip hybridization experiments were performed in order to examine genes differentially expressed upon inoculation of resistant and susceptible wheat cultivars with powdery mildew. Some genes were identified which were just expressed in the susceptible host both after mock-inoculation and pathogen infection. Also, a total of 2693 transcripts were differentially expressed (fold change≥2) in Yumai 13 in response to powdery mildew as compared to itself, comprising 1464 and 1229 up- and down-regulated genes respectively.
