Project description:In conifer forests of Northern Europe, a pathogenic fungus Heterobasidion annosum attacks the roots of Scots pine and causes mortality. Trees with infection grow slower and produce less timber with reduced quality. Despite applied control methods, such as switching tree species to a non-host species, or stump treatment, root and butt rot continues to be a serious forest health problem. Disease resistance breeding is a less-applied control method which has potential to improve tree health. However, neither conifer genotypes with absolute resistance to Heterobasidion sp. nor robust selection markers for resistance breeding have been found. We studied the responses of various Scots pine genotypes to Heterobasidion annosum infection and mechanic damage in drained peatland. Stems and roots of mature naturally regenerated Scots pine trees growing in drained peatland were either artificially infected with H. annosum or wounded and inoculated with sterile inoculum. Untreated trees from the study sites served as controls. Responses of different Scots pine genotypes to pathogen infection as determined by lesion size were recorded from samples harvested four months after inoculation, and least susceptible and highly susceptible genotypes were selected from the study material. Analysis of terpenoids from both least susceptible and highly susceptible pine genotypes by gas chromatography coupled with mass spectrometry indicates that some monoterpenes and sesquiterpenes are differentially induced depending on the susceptibility level. Transcriptomic microarray analysis was therefore conducted with RNA from stems of the least susceptible and highly susceptible Scots pine genotypes. Gene expression data from cDNA microarray were analysed by comparisons between the treatments, and the genotypes with different resistance level. The aim of the study is to highlight transcripts specific to differing levels of susceptibility.

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 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). Cultures were harvested after 3 weeks of incubation 22°C in darkness. All samples were labeled with Cy3.
