Next-generation interaction screening to discover protein-protein interactions regulating barley powdery mildew disease immunity and susceptibility.

Project description:The goals of this study were to identify novel proteins involved in barley immune responses. Yeast-two-hybrid (Y2H) screening was coupled with next-generation sequencing to identify and quantify interacting proteins. Y2H baits consisted of Blumeria graminis effector proteins and different domains of the barley MLA6 powdery mildew resistance protein. These baits were mated to a cDNA prey library derived from a 0-48 hour time course of infected leaf tissue. Screens were performed in batch liquid culture to enrich yeast populations for cells expressing positive interactions. After two rounds of enrichment under selective (Histidine absent) and non-selective (Histidine present) conditions, yeast cells were collected. Y2H plasmids were extracted and prey cDNA amplicons were generated via low-cycle PCR. Fragmented amplicons were used as input to generate sequencing libraries and processed on the HiSeq 3000 platform. Reads were mapped to the barley and Blumeria graminis genomes and read counts were analyzed using a custom data processing and scoring pipeline. Putative interactors were cloned and binary Y2H was used to confirm interactions. We demonstrate a high rate of confirmations for top-ranked candidates. Altogether, this study establishes a high-throughput method for protein-protein interaction discovery in non-model organisms where ORF libraries are not available.

Iso-Seq analysis of barley CI 16151 and fast-neutron-derived, immune-compromised mutants infected with the powdery mildew fungus (Blumeria graminis f. sp. hordei; isolate 5874)

Project description:Purpose: The powdery mildew fungus, Blumeria graminis, is an obligate biotrophic pathogen of cereals and has significant impact on food security (Dean et al., 2012. Molecular Plant Pathology 13 (4): 414-430. DOI: 10.1111/j.1364-3703.2011.00783.x). Blumeria graminis f. sp. hordei (Bgh) is the causal agent of powdery mildew on barley (Hordeum vulgare L.). We sought to discover novel transcripts expressed following barley infection with blumeria.

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

Transcriptomic comparison between the powdery mildew resistant and susceptible progenies of distant hybridization between Brassica carinata and Brassica napus

Project description:Powdery mildew caused by Erysiphe cruciferarum, is an epidemic of oil rapeseed (Brassica napus) growing worldwide, but resistant germplasm is rare in this species. We obtained the hybrid seeds of distant hybridization between powdery-mildew-immune Brassica carinata cultivar ‘White flower’ and susceptible B. napus cultivar ‘Zhongshuang11’. Five lines in the BC1F3 generation (F3 after backcross to 'Zhongshuang11') were identified to be resistant or moderately resistant. In order to identify the important biological responses to powdery mildew, the foliar transcriptomes of the resistant and susceptible plants in these progenies after powdery mildew inoculation were compared by using Illumina RNA-seq. We identified 10,454 differential expression genes (DEGs) and 1050 genes out of them are related to disease resistance. There were 271 DEGs in Group Resistance expressed at least two fold higher than in group S, while 779 DGEs expressed two fold lower. The genes highly expressed in Group Resistance are those encoding the proteins: (1) related to wax, chloroplast and cell wall metabolism, such as KCS6, CSP41B, RWA, callose synthetase 3, pectinase 9, fructosidase 2, 9s-lipoxygenase LOX2, etc.; (2) kinases including RKL, ERECTA, BAK1, BAM2, LysM receptor like kinase, and lipid transfer protein kinase ERl1 and ERl2; (3) broad spectrum powdery mildew resistance proteins RPW8, calmodulin MLO2, PMR5, MLP328, EDR2, RPS4 and RPS6, etc. In group susceptible, pectinesterase, cytochrome CYP81f2, LOX1, cysteine rich receptor protein kinases and serine / threonine protein kinases such as MEKK, RLK6, CRK45, APK1, BRl3, WAK1, WAK10, etc., and TIR-NB-LRR receptor like proteins R1M1, DSC1, DSC2 and pathogenesis-related protein PR-1 etc. were the most activated genes. The results provide the preliminarily knowledge about molecular mechanism in rapeseed defense response to powdery mildew.

comparison of powdery mildew-induced gene expression between Col-0 and the edr1 mutant

Project description:The edr1 mutant of Arabidopsis thaliana displays enhanced resistance to the powdery mildew Golovinomyces cichoracearum, resulting in cell death and an absence of visible disease symptoms. To better characterize and understand the defense response of edr1, a time course of early signaling responses was performed after inoculation with powdery mildew and compared to the responses of wild-type Col-0. These time points represent early stages in the infection process, before any signs of susceptibility or resistance are visible.
