Project description:Illumina technology was used to generate mRNA profiles of galls from root-knot nematodes infected and corresponding uninfected roots from Poplar CAD and WT lines. RNA was extracted from 3 replicates.TruSeq mRNA Stranded libraries were constructed and after pooling and normalization of libraries, sequencing was done on a NextSeq500 Sequencing System. Raw reads were trimmed for quality and mapped to the substituted genome sequence of P. tremula x P. alba 717-1B4 using CLC Genomics Workbench v9.5.2 and the primary transcripts only.
Project description:Illumina technology was used to generate mRNA profiles of leaves, roots and Laccaria bicolor mycorrhiza of Poplar treated with ozone or stopped watering. Total RNA was extracted separately from each plant and pooled to 4 biological replicates per condition.TruSeq mRNA Stranded libraries were constructed and and sequenced using Illumina HiSeq 3000 at the Genotoul sequencing facilities (Toulouse, France). Raw reads were filtered and trimmed using erne-filter command. Filtered reads from each library were aligned to P. trichocarpa (https://phytozome-next.jgi.doe.gov/info/Ptrichocarpa_v4_1) using TopHat2 v2.12.
Project description:affy_genomic_poplar - affy_genomic_poplar - The project aims to identify genes of interest for water deficit acclimation in poplar. We look for genes and gene expression networks related to drought stress in two hybrid cultivars, differing in their drought tolerance in field. Affymetrix poplar genome array was designed on several Populus species. In order to deal with comparative approaches, we checked the convenience of the array by hybridizing genomic DNA of the two hybrid cultivars (Populus deltoides × Populus nigra, namely ‘cv Carpaccio’ and ‘cv Soligo’). This point is important as transcript sequence might have diverged in the two genomes (Fossati et al, 2005), which could lead to absence of hybridization without physiological meaning. -Two poplar cultivars, Soligo (S) and Carpacio (C) were grown in controlled conditions. Mature leaves were collected and genomic DNA was extracted from leaves in CTAB buffer. gDNA was fragmented with DNAse1. DNA fragments were labelled with Biotin N6-ddATP and hybridized on Affymetrix poplar genome array. Two technical replicates per genotype were performed. Keywords: genomic comparison,gain of fuction epimutation

Project description:Global gene expression pattern of different poplar tissue types were determined using a Nimblegen microarray based on JGI v1.1 gene models. All tissue except reproductive tissue were obtained from the same clone used for the poplar genome sequencing project (Populus trichocarpa Nisqually-1). Reproductive tissue were from wild Populus trichocarpa trees.
