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

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.

This study should highlight telia-specific transcripts and contribute to the understanding of the poplar rust biological cycle. We performed 12 hybridizations (NimbleGen) with samples derived from resting urediniospores (3 biological replicates), infected poplar leaves harvested at 96 and 168 hpi (3 biological replicates each) and Telia (3 biological replicates). All samples were labeled with Cy3.

Project description:Microarray 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 with spores of avirulent strain 93ID6 of the pathogenic rust fungus Melampsora larici-populina (incompatible interaction, I48). 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. Competitive hybridization between transcripts of incompatible interaction (I48) and control condition (T48) was done on Populus PICME 28K cDNA microarray. Keywords: Time-course infection of plant tissue, defense response, cDNA microarray

Project description:cDNA macroarray 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, I) or spores of virulent strain 98AG31 (compatible interaction, C) of the pathogenic rust fungus Melampsora larici-populina. Besides, we mock-inoculated 'Beaupré' leaves with water (control condition, T). Detached leaves were maintained in vitro in controled conditions to allow fungal infection and colonization of plant tissue. Leaves were sampled at 12, 24 and 48 hours post-inoculation (hpi) in a time-course experiment before (12 hpi) and after (24 and 48 hpi) that the fungus attempt to penetrate plant cells in mesophyll.

Project description:Illumina HiSeq2500 technology was used to generate mRNA-sequencing expression profiles of sexual stages of the poplar rust fungus M. larici-populina: - Basidia (BSD) were collected from rust-infected dead poplar leaves; - Pycnia (PYC) -also called spermogonia- were collected from rust-infected larch needles one week after inoculation with basidiospores and corresponded to different haploid fungal cell types such as in planta infection hyphae, receptive hyphae and pycniospores; - Aecia (AEC) were collected from rust-infected larch needles two weeks after inoculation, and corresponded to freshly produced aecia and dikaryotic aeciospores and remaining pycnia. Paired-end reads of 100bp were generated for three sets of biological replicates corresponding to each of the targeted stage and aligned to the genome of M. larici-populina isolate 98AG31 (version 2.0; US Department of Energy Joint Genome Institute; http://genome.jgi.doe.gov/Mellp2_3/Mellp2_3.home.html) using CLC Genomics Workbench 12.0

Project description:Expression of defense response-related transcripts could be affected upon leaf wounding such as after excision of leaf disks. In this experiment, transcripts were isolated from whole leaves and 5-cm2 excised leaf disks samples from interaction assays between leaves of the 'Beaupré' poplar cultivar (Poplus trichocarpa x Poplus deltoides) and virulent (98AG31, compatible interaction) and avirulent (93ID6, incompatible interaction) urediniospores of Melampsora larici-populina, the fungus responsible for the foliar rust disease in poplar. For each type of interaction, three samples were collected in a time-course series (18, 21 and 24 hpi for strain 93ID6, and 18, 24 and 48 hpi for strain 98AG31). Both leaf disks and whole leaves were inoculated in strictly similar conditions, so differential transcript expression is likely attributable to the wounding effect in leaf disks. The aim of this study is to identify genes that are induced by wounding in leaf disks compared with whole leaves. For this purpose, cDNA templates were used for hybridization on poplar oligoarrays.

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.
