Transcription profiling of wild type and TaPrx103 over-expressing wheat plants subjected to pathogen attack by Blumeria graminis f.sp. tritici

ABSTRACT: Transgenic wheat plants of cv. Bobwhite were generated that constitutively overexpress class III peroxidase cDNA TaPrx103 (previously TaPERO) under the control of the epidermis-specific GstA1 promoter. Several transgenic lines show enhanced pathogen resistance. In order to test the concept of substantial equivalence, wildtype and transgenic lines were subjected to pathogen attack by Blumeria graminis f.sp. tritici, followed by transcript profiling using the barleyPGRC1 cDNA array.

Regulation of hormone pathways in wheat infested by Blumeria graminis f. sp. tritici.

Project description:BackgroundWheat powdery mildew is an obligate biotrophic pathogen infecting wheat, which can pose a serious threat to wheat production. In this study, transcriptome sequencing was carried out on wheat leaves infected by Blumeria graminis f. sp. tritici from 0 h to 7 d.ResultsKEGG and GO enrichment analysis revealed that the upstream biosynthetic pathways and downstream signal transduction pathways of salicylic acid, jasmonic acid, and ethylene were highly enriched at all infection periods. Trend analysis showed that the expressions of hormone-related genes were significantly expressed from 1 to 4 d, suggesting that 1 d-4 d is the main period in which hormones play a defensive role. During this period of time, the salicylic acid pathway was up-regulated, while the jasmonic acid and ethylene pathways were suppressed. Meanwhile, four key modules and 11 hub genes were identified, most of which were hormone related.ConclusionThis study improves the understanding of the dynamical responses of wheat to Blumeria graminis f. sp. tritici infestation at the transcriptional level and provides a reference for screening core genes regulated by hormones.

LC-MSMS of Hordeum vulgare epidermis containing haustoria from Blumeria graminis f.sp. hordei

Project description:Blumeria graminis f.sp. hordei is an obligate biotrohic fungal pathogen causing powdery mildew in barley. As for other biotrophic fungi, haustorial structures are at the centre of the biotrophic interaction and molecular exchanges, delivering fungal effectors or virulence factors, and taking nutrient from the host. Haustoria are originiated by the fungus, following successful penetration of the initial penetration peg through the plant cell call. Haustorial structures mainly of fungal origin, but they are surrounding by a plant component, the extrauhaustorial membrane and matrix (EHM and EHMx) forming the extrahuastorial complex (EHMc). The plant protein make-up of the plant extrahaustorial components remained unexplored, and this is a first study trying to describe plant proteome associated with haustoria using samples enriched for these structures. Therefore, proteomes of haustoria enriched samples from the epidermis of barley leaves infected with Blumeria graminins f.sp. hordei, the causing agent of barley powdery mildew, were compared to infected epidermis and un-infected epidermis to identify haustoria associated plant proteins. Haustoria were enriched from infected epidermis by digesting epidermal cell walls with cell wall degrading enzymes prior to enrichment for haustorial structures. Proteins identified in these samples were compared to infected and uninfected epidermis samples using a non-targeted label free semi-quantitation method.

Mapping Powdery Mildew (Blumeria graminis f. sp. tritici) Resistance in Wild and Cultivated Tetraploid Wheats.

Project description:Wheat is the most widely grown crop and represents the staple food for one third of the world's population. Wheat is attacked by a large variety of pathogens and the use of resistant cultivars is an effective and environmentally safe strategy for controlling diseases and eliminating the use of fungicides. In this study, a collection of wild and cultivated tetraploid wheats (Triticum turgidum) were evaluated for seedling resistance (SR) and adult plant resistance (APR) to powdery mildew (Blumeria graminis) and genotyped with a 90K single nucleotide polymorphism (SNP) array to identify new sources of resistance genes. The genome-wide association mapping detected 18 quantitative trait loci (QTL) for APR and 8 QTL for SR, four of which were identical or at least closely linked to four QTL for APR. Thirteen candidate genes, containing nucleotide binding sites and leucine-rich repeats, were localized in the confidence intervals of the QTL-tagging SNPs. The marker IWB6155, associated to QPm.mgb-1AS, was located within the gene TRITD1Av1G004560 coding for a disease resistance protein. While most of the identified QTL were described previously, five QTL for APR (QPm.mgb-1AS, QPm.mgb-2BS, QPm.mgb-3BL.1, QPm.mgb-4BL, QPm.mgb-7BS.1) and three QTL for SR (QPm.mgb-3BL.3, QPm.mgb-5AL.2, QPm.mgb-7BS.2) were mapped on chromosome regions where no resistance gene was reported before. The novel QTL/genes can contribute to enriching the resistance sources available to breeders.
