Project description:Transcript profiles of Laccaria bicolor S238N mycelium on various media were analyzed. The array probes were designed from gene models taken from the Joint Genome Institute (JGI, department of energy) Laccaria bicolor genome sequence version 1. One goal was to evaluate the effect of nutrient deprivation on the transcriptome of Laccaria bicolor.
Project description:Laccaria bicolor transcript profiles of different tissues and mycorrhizal root tips from different host trees were analyzed. The array probes were designed from gene models taken from the Joint Genome Institute (JGI, department of energy) Laccaria bicolor genome sequence version 1. One goal was to compare gene expression profiles from ectomycorrhizal root tips with different host plants.
Project description:The Transcriptome of different tissues and developmental stages of Laccaria bicolor S238N was analyzed. The array probes were designed from gene models taken from the Joint Genome institute Laccaria bicolor genome sequence version1. One aim of this study was to verify the expression of the automatically annotated gene models in various tissues and to use this transcriptional information to confirm, to correct or to reject gene models. Another goal was to identify tissue-specific gene expression, e.g. mycorrhiza up-regulated transcripts or fruiting body up-regulated transcripts, or treatment specific gene expression for further detailed analyses.

Project description:This study characterizes the transcriptomic alterations of P. tremula x P. alba at three weeks after inoculation with the ectomycorrhizal fungus Laccaria bicolor.
Project description:This study characterizes the transcriptomic alterations of Laccaria bicolor S238N during interaction with P. trichocarpa. Four time-points were analyzed, two weeks, four weeks , six weeks and twelve weeks after inoculation and compared to the transcriptome of free-living mycelium from Laccaria bicolor S238N
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. mRNA profiles from Populus trichocarpa roots colonized by Laccaria bicolor for two, four and 12 weeks as well as from control roots and free-living mycelium were generated by using one lane of 37 bp Illumina GAIIx sequencing per sample.
Project description:This study characterizes the transcriptomic alterations of Laccaria bicolor S238N during interaction with Pseudotsuga menziesii. Three time-points were analyzed, two weeks, four weeks and six weeks after inoculation and compared to the transcriptome of free-living mycelium from Laccaria bicolor S238N.
Project description:Transcript profiles of Laccaria bicolor S238N mycelium on various media were analyzed. The array probes were designed from gene models taken from the Joint Genome Institute (JGI, department of energy) Laccaria bicolor genome sequence version 1. One goal was to evaluate the effect of nutrient deprivation on the transcriptome of Laccaria bicolor. We performed 15 hybridizations (Roche-NimbleGen) with samples derived from Laccaria bicolor free-living mycelium grown on MMN medium, on MMN with a 10 times reduction in all major macro-elements, on MMN with a 10 times reduction in the quantity of glucose or onto agar medium supplemented with the same nutrients used to fertilize our mycorrhization experiments.
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.
