Heterobasidion annosum gene expression from mycelium grown on different substrates

ABSTRACT: Transcript profiles of H. annosum from mycelium grown on different substrates and under different stresses were analyzed. The array probes were designed from gene models taken from the Joint Genome Institute (JGI, department of energy) H. irregulare genome sequence version 1. One aim of this study was to compare gene expression profiles of H. annosum pre-grown on secondary metabolites from the biocontrol agent Phlebiopsis gigantea. We performed six hybridizations with samples derived from H. annosum grown in either liquid Malt Extract Medium (three biological replicates) or on secondary metabolite from Phlebiopsis gigantea (three biological replicates). The Heterobasidion irregulare custom-exon expression array (4 x 72K) manufactured by Roche NimbleGen Systems Limited (Madison, WI) (http://www.nimblegen.com/products/exp/index.html) contained five independent, non-identical, 60-mer probes per gene model coding sequence. For 12,199 of the 12,299 annotated protein-coding gene models, probes could be designed. For 19 gene models, no probes could be generated, and 81 gene models shared all five probes with other gene models. Included in the array were 916 random 60-mer control probes and labelling controls. For 2032 randomly chosen gene models, technical duplicates were included on the array.

Heterobasidion annosum gene expression from different tissues and mycelium grown on different substrates and under different biotic and abiotic stresses

Project description:Transcript profiles of H. annosum from different tissues and mycelium grown on different substrates and under different stresses were analyzed. The array probes were designed from gene models taken from the Joint Genome Institute (JGI, Department of Energy) H. irregulare genome sequence version 1. One aim of this study was to compare gene expression profiles of H. annosum grown on different substrates and under different biotic and abiotic stresses. We performed hybridizations (NimbleGen) with samples derived from H. annosum grown in either liquid Malt Extract Medium at 20Â°C (three biological replicates), under NaCl stress (three biological replicates), under CaCl2 stress (three biological replicates), at 8Â°C (three biological replicates), at 27Â°C (three biological replicates), saprotrophic growth on Scots pine sapwood (three biological replicates), bark (three biological replicates) or heartwood (three biological replicates). Additional hybridizations were performed with RNA from necrotrophic growth of Heterobasidion on Scots pine xylem (three biological replicates), necrotrophic growth on Scots pine phloem (three biological replicates), under nutrient starvation (three biological replicates) or under oxidative stress (three biological replicates). The Heterobasidion irregulare custom-exon expression array (4 x 72K) manufactured by Roche NimbleGen Systems Limited (Madison, WI) (http://www.nimblegen.com/products/exp/index.html) contained five independent, non-identical, 60-mer probes per gene model coding sequence.

Heterobasidion irregulare gene expression from different tissues and mycelium grown on different substrates

Project description:Transcript profiles of Heterobasion irregulare from different tissues and mycelium grown on different substrates were analyzed. The array probes were designed from gene models taken from the Joint Genome Institute (JGI, department of energy) Heterobasidion annosum genome sequence version 1. One aim of this study was to verify the expression of the automatically annotated gene models under various conditions. Another goal was to compare gene expression profiles from different tissues of Heterobasidion irregulare and from mycelium grown on liquid MMN medium, liquid medium amended with lignin or cellulose and on wood. The Heterobasidion annosum custom-exon expression array (4 x 72K) manufactured byRoche NimbleGen Systems Limited (Madison, WI) (http://www.nimblegen.com/products /exp/index.html) contained five independent, nonidentical, 60-mer probes per gene model coding sequence. For 12,199 of the 12,299 annotated protein-coding gene models probes could be designed. For 19 gene models no probes could be generated and 81 gene models shared all five probes with other gene models. Included in the array were 916 random 60-mer control probes and labelling controls. For 2032 randomly chosen gene models, technical duplicates were included on the array. We performed 18 hybridizations (NimbleGen) with samples derived from Heterobasidion irregulare fruiting bodies (four biological replicates) , from necrotic bark of pines inoculated with H. irregulare (21dpi; three biological replicates), from H. irregulare mycelium grown in liquid MMN medium (three biological replicates) as well as from H. irregulare grown on wood shavings from pine (four biological replicates), grown in liquid medium amended with lignin (2 biological replicates) and growth in liquid medium amended with cellulose from Spruce (2 biological replicates).

The black truffle of Perigord responds to a temperature shift with an extensive reprogramming of its transcriptional activity

Project description:Taking advantage of the availability of the Tuber melanosporum genome sequence and a whole-genome microarray, we wanted to test the hypothesis that the transition from a growth temperature of 24-25°C to a cold one (4°C) is perceived by the filamentous fungus at the transcriptomic level and we wanted to identify and characterize the genes involved in this stress response. The T. melanosporum custom-exon expression array (4 x 72K) manufactured by Roche NimbleGen Systems Limited (Madison, WI) contained five independent, nonidentical, 60-mer probes per gene model coding sequence. Included in the oligoarray were 12,232 annotated gene models, 3,913 random 60-mer control probes and labelling controls. Sequences used for the oligonucleotide design were from an early draft of the gene catalog containing several TE families. For 1,876 gene models, technical duplicates were included on the array. We performed 6 hybridizations (3 control and 3 treated) with samples derived from liquid cultures of T. melanosporum Mel28. After a month, some flasks were moved to 4°C for 1 week. After this period, the mycelium was collected from the treated (from 25°C to 4°C) and the untreated (25°C) control cultures. All samples were labeled with Cy3.

Laser capture microdissection and microarray analysis of ectomycorrhizas formed by the ascomycete Tuber melanosporum reveal functional heterogeneity between mantle and Hartig net compartments

Project description:The aim of this analysis was to better understand the complex symbiotic stage of Tuber melanosporum by combining the use of laser capture microdissection and microarray gene expression analysis. We isolated the fungal/soil (i.e. the mantle) and the fungal/plant (i.e. the Hartig net) interfaces from transverse sections of T. melanosporum/Corylus avellana ectomycorrhizas and identified the transcriptional landscape associated with each compartment. We compared these data to the transcriptome of ectomycorrhizal root tips, free-living mycelium and fruiting bodies of Tuber melanosporum (Series GSE17529). The T. melanosporum custom-exon expression array (4 x 72K) manufactured by Roche NimbleGen Systems Limited (Madison, WI) contained five independent, nonidentical, 60-mer probes per gene model coding sequence. Included in the oligoarray were 12,232 annotated gene models, 3,913 random 60-mer control probes and labelling controls. Sequences used for the oligonucleotide design were from an early draft of the gene catalog containing several TE families. For 1,876 gene models, technical duplicates were included on the array. We performed 6 hybridizations (NimbleGen) with samples derived from microdissected mantles (3 biological replicates) and Hartig nets ((3 biological replicates each) from T. melanosporum/Corylus avellana ectomycorrhizal root tips . 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.
