Project description:A microarray analysis of whole-genome gene expression and single feature polymorphism in a (Populus trichocarpa X Populus deltoides) X Populus deltoides pseudo-backcross pedigree. Genetic variation in gene expression was quantified for 55,793 predicted gene models based on a single probe per gene. Concurrently, sequence-level polymorphism was analyzed based on dedicated probes identified in a pilot study comprised of the two parent genotypes (GPL7169). Resultant data contributed to a high density genetic map and to analysis of the genetic architecture of gene expression in Populus. Keywords: Genetic analysis of gene expression and polymorphism, eQTL

Project description:The coordination of chloroplast and nuclear genome status are critical for plant cell function, but the mechanism remain largely unclear. In this study, we report that Arabidopsis thaliana CHLOROPLAST AND NUCLEUS DUAL-LOCALIZED PROTEIN 1 (CND1) maintains genome stability in both the chloroplast and the nucleus.

Resultant data contributed to a high density genetic map and to analysis of the genetic architecture of gene expression in Populus. Keywords: Genetic analysis of gene expression and polymorphism, eQTL Data include one biological replicate of 178 segregating pseudobackcross progeny analyzed for gene expression (GE) using one probe per gene for 55793 independent gene models (probes E_POPLARSxxxxxPxxxxx) and single feature sequence polymorphism (SFP) using one probe per gene for 12084 independent gene models (probes G_POPLARSxxxxxPxxxxx). GE and SFP probes were selected from 6-7 probes per gene previously tested in a pilot study of the two parent trees of the cross (Populus deltoides X Populus trichocarpa).

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.

Project description:In this study we employ a strand-specific RNA-seq appoach and stranded gene expression analysis tools to identify drought responsive antisense gene loci and sense-antisense gene pairs in Populus. we generated and sequenced 28 strand-specific cDNA libraries derived from either leaf or root tissues of Populus trichocarpa plants associaed with both short-term drought (24 hours of water stress of 40% of field capacity) and long-term drought ( 25 days of water stress of 40% of field capacity) . We mapped over 71 billion nucleotides to Populus genome. Our data demonstrates that with the current sequence depth ~ 19 % of Populus genome undergoes antisense transcription subjected to drought regulation. All in all we have identified that in root tissues 524 differentially expressed antisense genes and 247 drought-responsive SA gene pairs which are significantly regulated by drought (padj <0.05). Taken all data from both drought treatments, we have identified 1185 unique drought-responsive antisense gene loci and 606 drought-responsive SA gene pairs (padj <0.05).
