Comparative transcriptomic reveals signatures specific to various interactions with Melampsora rust fungi

ABSTRACT: We aim to understand the global transcriptional response of hybrid poplar NM6 (Populus nigra x Populus maximoviczii) to infection by two biotrophic Melampsora fungi, M. larici-populina and M. medusae f. sp. deltoidae separately and simultanously. Transcript profilling revealed 699 differentially expressed genes whose expression level was equal or higher than 2-fold between infected and noninfected tissues. In the mixed infection, our results showed an additive response of the two pathogens. Genes regulated as a result of Melampsora infection were generally induced and mainly involved in primary/secondary metabolism that include cell wall reinforcement and lignification, defense-related processes like pathogenesis-related and stress response, signal perception and transduction mechanisms and regulation of transcription. Keywords: Stress response

ORGANISM(S): Populus maximowiczii x Populus nigra Populus sp.

Melampsora larici-populina gene expression in different tissues and developmental stages

Project description:The transcriptome of Melampsora-larici-populina was analysed in urediniospores, germlings and during poplar leaf infection. The array probes were designed from gene models taken from the Joint Genome Institute (JGI, Department of Energy) Melampsora larici-populina genome sequence version 1. One aim of this study was to verify the expression of the automatically annotated gene models in various tissues and development stages. Another goal was to monitor gene expression profiles during poplar leaf infection and to highlight tissue-specific transcripts, e.g. in planta up-regulated transcripts for further analyses.

Melampsora larici-populina gene expression in different tissues and development stages

Project description:The transcriptome of Melampsora-larici-populina was analysed in urediniospores, germlings and infected Poplar leaves. The array probes were designed from gene models taken from the Joint Genome Institute (JGI, Department of Energy) Melampsora larici-populina genome sequence version 1. One aim of this study was to verify the expression of the automatically annotated gene models in various tissues and development stages. Another goal was to monitor gene expression at different developmental stages and to highlight tissue-specific transcripts, e.g. in planta up-regulated transcripts for further analyses. We performed 9 hybridizations (Nimblegen) with samples derived from urediniospores, germlings and infected Poplar leaves (three replicates each). Samples from infected leaves were harvested 96 hours post infection. All samples were labeled with Cy3.

Early infection of poplar leaves by the rust pathogen Melampsora larici-populina

Project description:The identification of early-expressed pathogen effectors and early-modulated host functions is currently a major goal to understand the molecular basis of biotrophic lifestyle. Melampsora larici-populina isolates 98AG31 and 93ID6, respectively virulent and avirulent on the hybrid P. trichocarpa x P. deltoides poplar cultivar M-bM-^@M-^XBeauprM-CM-)M-bM-^@M-^Y were used in this study. Inoculations were performed on 5 cm2 leaf disks. The following conditions were used for oligoarrays: Incompatible 18, 21 and 24 hpi, Compatible 18, 24 and 48hpi. One aim of this study was to compare RNA-Seq and hybridization-based approaches, therefore the cDNA templates were used for whole-genome poplar oligoarrays and 454-pyrosequencing. We performed 6 hybridizations (Nimblegen) with samples derived from incompatible (18, 21 and 24hpi) and compatible (18, 24 and 48hpi) interactions of Melampsora larici-populina with P. trichocarpa x P. deltoides poplar cultivar M-bM-^@M-^XBeauprM-CM-)M-bM-^@M-^Y leaves. All samples were labeled with Cy3.

Melampsora larici-populina gene expression in telia, uredinia, urediniospores and in planta

Project description:The transcriptome of Melampsora larici-populina was analysed in telia (in planta sample, early telia harvested before overwintering), uredinia (in planta sample, 168 hours post-inoculation, hpi), in planta during biotrophic growth (96 hpi) and in resting urediniospores. The array probes were designed from gene models taken from the Joint Genome Institute (JGI, Department of Energy) Melampsora larici-populina genome sequence version 1. The aim of this study was to determine gene expression in early telia formed in decaying poplar leaves in autumn before the overwintering process and to compare this expression with other stages of the poplar rust life cycle that were previously described (i.e., resting urediniospores as pure fungal material, and uredinia and biotrophic growth stage as poplar leaf infecting fungal structures). This study should highlight telia-specific transcripts and contribute to the understanding of the poplar rust biological cycle.

Identification of rust-induced genes in poplar using Populus 2.0 NimbleGen oligoarray

Project description:Oligoarray expression profiling was carried out in poplar leaves upon infection with rust in order to identify genes expressed during tree defense response. For this purpose, we inoculated detached leaves of the interamerican hybrid poplar Populus trichocarpa x Populus deltoides 'Beaupré' grown in greenhouse either with spores of avirulent strain 93ID6 (incompatible interaction I48) or spores of virulent strain 98AG31 (compatible interaction C48) of the pathogenic rust fungus Melampsora larici-populina. Besides, we mock-inoculated 'Beaupré' leaves with water (control condition, T48). Detached leaves were maintained in vitro in controled conditions to allow fungal infection and colonization of plant tissue. Leaves were sampled 48 hours post-inoculation after that the fungus attempt to penetrate plant cells in mesophyll. Keywords: Plant tissue infection, Plant defense response, Oligonucleotide array

Melampsora larici-populina gene expression in different tissues of uredinia

Project description:Laser Capture Microdissection (LCM) was used for expression analysis of three contrasted fungal tissues of uredinia corresponding respectively to spores and sporogenous hyphae, fungal structures in the spongy mesophyll and fungal infection structures in the palisade mesophyll. The array probes were designed from gene models taken from the Joint Genome Institute (JGI, Department of Energy) Melampsora larici-populina genome sequence version 1. The aim of this study was to identify tissue-specific gene expression to gain insights into the genes specifically associated with the biotrophic phase and the sporulation phase of the rust fungus. We performed 9 hybridizations (NimbleGen) with samples derived from Laser Capture Microdissection (LCM) of three contrasted fungal tissues of uredinia, corresponding respectively to spores and sporogenous hyphae, fungal structures in the spongy mesophyll and fungal infection structures in the palisade mesophyll. Three replicates per tissue. All samples were labeled with Cy3.
