Project description:Illumina HiSeq2000 technology was used to generate mRNA profiles from the ectomycorrhizal fungi Laccaria bicolor colonizing roots of Populus trichocarpa. Samples were taken after 3 months of contact in order to identify mycorrhiza-regulated transcripts. 100bp reads were generated and aligned to the Populus trichocarpa (http://www.phytozome.net/poplar.php) reference genome.

Project description:Stem cuttings of P. trichocarpa (clone 101-74) were rooted in liquid medium without growth regulators (basal medium). The first emerging roots were observed on cuttings 6 days after the start of culture. The highest average root number per cutting (10 ± 2 roots/cutting) was obtained after 14 days. The first macroscopic evidence of root initiation was the appearance of root primordia, as lateral bulges observed at the stem surface 3 to 4 days after transfer to basal medium. Stem cross-sections showed intensely dividing cells forming root primordial. One to two days later the bark split and the organized sequence of cell division and differentiation steps in the primordium led to the establishment of the main root tissues, as well as the vascular connections of the incipient root with the pre-existing stem vasculature. Subsequently, the outgrowth and emergence of the adventitious root occurred. We refer to the dormant cutting as stage 0, the organizing primordium as stage 1, the primordium differentiation as stage 2. To examine changes in gene transcription associated with the development of adventitious roots, we monitored the transcript levels in differentiating primordia using microarrays. cDNA was prepared from replicate sets of P. trichocarpa rooted cuttings harvested at stages 0, 1 and 2. The Populus whole-genome expression array version 2.0 manufactured by NimbleGen Systems Limited (Madison, WI) contains in duplicates three independent, non-identical, 60-mer probes per whole gene model plus control probes and labeling controls. Included in the microarray are 65,965 probe sets corresponding to 55,970 gene models predicted on the P. trichocarpa genome sequence version 1.0 and 9,995 aspen cDNA sequences (Populus tremula, Populus tremuloides, and P. tremula x P. tremuloides). NimbleGen whole genome microarray analyses were performed in triplicate as per manufacturers instructions. We carried out nine hybridizations (NimbleGen) with samples derived from three early developmental stages of P. trichocarpa adventitious roots. cDNA was synthesized using CLONTECH Smart cDNA Synthesis kit containing an amplification step on the cDNA level. All samples were labeled with Cy3.

Project description:A microarray analysis of whole-genome gene expression in leaves was carried out 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. Resultant data contributed to the analysis of the genetic architecture of gene expression in leaves of Populus.

Project description:Illumina GAIIx technology was used to generate mRNA profiles from the ectomycorrhizal fungi Laccaria bicolor colonizing roots of Populus trichocarpa. Samples were taken after two, four and 12 weeks of contact in order to identify mycorrhiza-regulated transcripts. 37bp reads were generated and aligned to the Populus trichocarpa (http://www.phytozome.net/poplar.php) and the Laccaria bicolor (http://genome.jgi-psf.org/Lacbi2/Lacbi2.home.html) reference genomes using CLC Genomics Workbench 6.

Project description:A microarray analysis of whole-genome gene expression in leaves was carried out 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. Resultant data contributed to the analysis of the genetic architecture of gene expression in leaves of Populus. Data include one biological replicate of 183 individuals segregating from a pseudo-backcross pedigree of (Populus trichocarpa X Populus deltoides) X Populus deltoides analyzed for gene expression (GE) in roots 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)
