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.

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.

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.

Project description: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.

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.

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.
