Dual transcriptomic analysis of the interaction between the ectomycorrhizal fungus Laccaria bicolor S238N and soil Collimonas fungivorans Ter331

ABSTRACT: In order to get insights into the ability of ectomycorrhizal fungi to perceive their biotic environment as well as into the mechanisms of the interactions between ectomycorrhizal fungi and soil bacteria, we analysed the transcriptomic response of the ectomycorrhizal fungus L. bicolor and one detrimental bacterial strain during their interactions in vitro. We performed hybridizations (whole genome array) with samples derived from Collimonas fungivorans Ter331cultivated alone or with Laccaria bicolor S238N in vitro (2 control biological replicates and 2 biological replicates with L. bicolor)

Mycorrhizal Metabolome: L. bicolor :: P. trichocapra

Project description:Mycorrhizae, symbiotic interactions between soil fungi and tree roots, are ubiquitous in terrestrial ecosystems. The fungi contribute phosphorous, nitrogen and mobilized nutrients from organic matter in the soil and in return the fungus receives photosynthetically-derived carbohydrates. This union of plant and fungal metabolisms is the mycorrhizal metabolome. Understanding this symbiotic relationship at a molecular level provides important contributions to the understanding of forest ecosystems and global carbon cycling. We generated next generation short-read transcriptomic sequencing data from fully-formed ectomycorrhizae between Laccaria bicolor and aspen (Populus tremuloides) roots. The transcriptomic data was used to identify statistically significantly expressed gene models using a bootstrap-style approach, and these expressed genes were mapped to specific metabolic pathways. Integration of expressed genes that code for metabolic enzymes and the set of expressed membrane transporters generates a predictive model of the ectomycorrhizal metabolome. Results indicate the specific compounds glycine, glutamate, and allantoin are synthesized by L. bicolor and that these compounds or their metabolites may be used for the benefit of aspen in exchange for the photosynthetically-derived sugars fructose and glucose.The analysis illustrates an approach to generate testable biological hypotheses to investigate the complex molecular interactions that drive ectomycorrhizal symbiosis. These models are consistent with experimental environmental data and provide insight into the molecular exchange processes for organisms in this complex ecosystem. The method used here for predicting metabolomic models of mycorrhizal systems from deep RNA sequencing data can be generalized and is broadly applicable to transcriptomic data derived from complex systems.

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.

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.

Comparison of gene expression in roots from Populus trichocarpa and Populus deltoides colonized with Laccaria bicolor

Project description:The majority of trees live in association with symbiotic fungi, which facilitate their access to soil nutrients. The ectomycorrhizal symbiosis represents a complex biological system involving multifaceted interactions between the two partners. The establishment of the symbiosis depends on various conditions (e.g. climate), but also on the genetic traits of the partners. To evaluate the impact of the genetic predisposition on the development and functioning of ectomycorrhizas, we compared the transcriptome of roots from Populus trichocarpa and Populus deltoides colonized with Laccaria bicolor. The Populus whole-genome expression array version 2.0 (S. DiFazio, A. Brunner, P. Dharmawardhana, and K. Munn, unpublished data) 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 manufacturer's instructions. We carried out six hybridizations (NimbleGen) with samples derived from Populus trichocarpa and Populus deltoides mycorrhizal root tips. Three samples (biological replicates) originated from Populus trichocarpa (GSM648401, GSM648403, GSM648405) and three biological replicates from Populus deltoides (GSM648408, GSM648411, GSM648414). cDNA was synthesized using CLONTECH Super Smart cDNA Synthesis kit containing an amplification step on the cDNA level. 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.

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.
