Project description:Gastrodia elata Blume (Orchidaceae) is an important Chinese medicine with several functional components. In the life cycle of G. elata, the orchid develops a symbiotic relationship with two compatible mycorrhizal fungi Mycena spp. and Armillaria mellea during seed germination to form vegetative propagation corm and vegetative growth to develop tubers, respectively. Gastrodin (p-hydroxymethylphenol-beta-D-glucoside) is the most important functional component in G. elata, and gastrodin significantly increases from vegetative propagation corms to tubers. To address the gene regulation mechanism in gastrodin biosynthesis in G. elata, a comparative analysis of de novo transcriptome sequencing among the vegetative propagation corms and tubers of G. elata and A. mellea was conducted using deep sequencing. Transcriptome comparison between the vegetative propagation corms and juvenile tubers of G. elata revealed 582 differentially expressed unigenes, of which 415 and 167 genes were, respectively up-regulated (fold-change â?¥ 2, p-value < 0.05) and down-regulated (fold-change â?¤ 0.5, p-value <0.05) in juvenile tubers. After Gene Ontology (GO) annotation and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analyses, forty-seven up-regulated unigenes with enzyme commission (EC) were assigned to 269 isogroups involved in 100 different pathways, and twenty-four down-regulated unigenes with enzyme commission (EC) were assigned to 586 isogroups, involved in 167 different pathways. The analysis of the isogroup genes from all pathways revealed that the two unigenes at locus 25,051 (one of monooxygenases) and locus 22,288 (one of glycosyltransferases) might participate in hydroxylation and glucosylation in the gastrodin biosynthetic pathway. The gene expression of the two unique unigenes encoding monooxygenase and glycosyltransferase significantly increases from vegetative propagation corms to tubers, and the molecular basis of gastrodin biosynthesis in the tubers of G. elata is proposed.

Project description:The genus Armillaria spp. (Fungi, Basidiomycota) includes devastating pathogens of temperate forests and saprotrophs that decay wood. Pathogenic and saprotrophic Armillaria species can efficiently colonize and decay woody substrates, however, mechanisms of wood penetration and colonization are poorly known. We assayed the colonization and decay of autoclaved spruce roots using the conifer-specialists Armillaria ostoyae and A. cepistipes using transcriptomic and proteomic data. Transcript and protein levels were altered more extensively in the saprotrophic A. cepistipes than in the pathogenic A. ostoyae and in invasive mycelia of both species compared to their rhizomorphs. Diverse suites of carbohydrate-active enzyme genes (CAZymes), in particular pectinolytic ones and expansins, were upregulated in both species, whereas ligninolytic genes were mostly downregulated. Our gene expression data, together with previous comparative genomic and decay-chemistry analyses suggest that wood decay by Armillaria differs from that of typical white rot fungi and shows features resembling soft rot. We propose that Armillaria species have modified the ancestral white rot machinery so that it allows for selective ligninolysis based on environmental conditions and/or host types.
