Laccaria-Douglas fir: A Timecourse of Mycorrhizal Root Tip Development

ABSTRACT: 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.

Laccaria-Douglas fir: A Timecourse of Mycorrhizal Root Tip Development

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. We performed 9 hybridizations (NimbleGen) with samples derived from Pseudotsuga menziesii /L.bicolor mycorrhizal root tips. Samples were taken after 2,4 and 6 weeks of interaction (three biological replicates). These samples were compared to free-living mycelium from Laccaria bicolor S238N (three biological replicates). All samples were labeled with Cy3.

Laccaria-Poplar: A Timecourse of Mycorrhizal Root Tip Development

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 We performed 16 hybridizations (NimbleGen) with samples derived from P.trichocarpa/L.bicolor mycorrhizal root tips. Samples were taken after 2,4,6 and 12 weeks of interaction (four biological replicates). These samples were compared to free-living mycelium from Laccaria bicolor S238N (three biological replicates). All samples were labeled with Cy3.

Poplar-Laccaria: A Timecourse of Mycorrhizal Root Tip Development

Project description:This study characterizes the transcriptomic alterations of P. trichocarpa during interaction with the ectomycorrhizal fungus Laccaria bicolor S238N. Four time-points were analyzed, two weeks, four weeks , six weeks and twelve weeks after inoculation. We performed 32 hybridizations (NimbleGen) with samples derived from Populus trichocarpa control roots and P.trichocarpa mycorrhizal root tips. Samples were taken after 2,4,6 and 12 weeks of interaction (four biological replicates). All samples were labeled with Cy3.

Gene expression of Laccaria bicolor S238N free-living mycelium grown on different media

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.

Poplar-Laccaria Mycorrhizal Roots

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. We performed 6 hybridizations (NimbleGen) with samples derived from Populus tremula x P. alba control roots and mycorrhizal root tips. Samples were taken after 3 weeks of interaction (three biological replicates). All samples were labeled with Cy3.

Transcriptome analyses of the Laccaria bicolor-Populus trichocarpa mycorrhiza development

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.
