The complete mitochondrial genome of wood-rotting fungus Xylaria hypoxylon.

ABSTRACT: Xylaria hypoxylon is a noticeable black fungus, and also habitual to cluster on rotting wood. In this study, the high-quality whole-genome of X. hypoxylon strain SFY20170806 was sequenced on the Illumina sequencing platform. The complete mitochondrial genome of X. hypoxylon was assembled and annotated. The single circular structure of 129,366 bp length is the largest species found in the order Xylariales. The overall GC content is 29.7% and gene composition includes 13 protein-coding genes (PCGs), 30 transfer RNA genes(tRNA), 2 ribosomal RNA genes(rRNA) and 6 open reading frames (ORF). Phylogenetic tree was constructed to validate the evolutionary relationship based on the complete mitogenomes from twelve taxa of four species of Xylariales, four species of Hypocreales, two species of Helotiales, one species of Microascales and X. hypoxylon. Phylogenetic analysis demonstrated that X. hypoxylon has a special evolutionary status and close genetic relationship with Annulohypoxylon stygium.

Data on the genome analysis of the wood-rotting fungus Steccherinum ochraceum LE-BIN 3174.

Project description:In the present article, we report data on the whole-genome sequencing of wood-rotting (white-rot) fungus Steccherinum ochraceum LE-BIN 3174. The S. ochraceum LE-BIN 3174 genome consists of 770 scaffolds (N50 = 62,812 bp) with the total length of assembly ∼35 Mb. The structural annotation of the genome resulted in the prediction of 12,441 gene models, among which 181 were models of tRNA-coding genes, and 12,260 - protein-coding genes. The protein-coding genes were annotated with different databases (Pfam, InterPro, eggNOG, dbCAN, and MEROPS). The whole genome sequence and functional annotation provide an important information for the deep investigation of biochemical processes that take place during the late stages of wood decomposition by Basidiomycetes. The Whole Genome project of S. ochraceum LE-BIN 3174 had been deposited at DDBJ/ENA/GenBank under the accession RWJN00000000. The version described in this work is version RWJN00000000.1. For further interpretation of the data provided in this article, please refer to the research article "Fungal Adaptation to the Advanced Stages of Wood Decomposition: Insights from the Steccherinum ochraceum" [1].

The application of the name Xylaria hypoxylon, based on Clavaria hypoxylon of Linnaeus.

Project description:Although Xylaria hypoxylon is one of the most familiar fungi of temperate regions, the basionym of the name, Clavaria hypoxylon of Linnaeus, has remained untypified. Here we assess the original five elements included in the 1753 protologue; no candidate specimen was located but two illustrations Linnaeus cited were considered, one a mixture of species and the other fanciful. As the name is sanctioned, following clarifications in the Melbourne Code, elements cited by Fries when the name was sanctioned in 1823 are also candidates for lectotypification. In addition to various illustrations, Fries cites two exsiccatae, and one from his own Scleromycetes Suecicae distributed in 1821 is designated as lectotype for Linnaeus' name here. In view of the complexity of the group as revealed by molecular systematic work, and the poor state of the Fries material, we also designate a sequenced epitype from Sweden. We stress the importance of examining fungi in the complex in the sexual state, as those that are asexual can be difficult to identify conclusively. Figures of the original protologues and the most pertinent illustrations and specimens are provided, along with a detailed description and illustrations based on recent collections.

Complete mitochondrial genome of the medicinal fungus Ophiocordyceps sinensis.

Project description:As part of a genome sequencing project for Ophiocordyceps sinensis, strain 1229, a complete mitochondrial (mt) genome was assembled as a single circular dsDNA of 157,510?bp, one of the largest reported for fungi. Conserved genes including the large and small rRNA subunits, 27 tRNA and 15 protein-coding genes, were identified. In addition, 58 non-conserved open reading frames (ncORFs) in the intergenic and intronic regions were also identified. Transcription analyses using RNA-Seq validated the expression of most conserved genes and ncORFs. Fifty-two introns (groups I and II) were found within conserved genes, accounting for 68.5% of the genome. Thirty-two homing endonucleases (HEs) with motif patterns LAGLIDADG (21) and GIY-YIG (11) were identified in group I introns. The ncORFs found in group II introns mostly encoded reverse transcriptases (RTs). As in other hypocrealean fungi, gene contents and order were found to be conserved in the mt genome of O. sinensis, but the genome size was enlarged by longer intergenic regions and numerous introns. Intergenic and intronic regions were composed of abundant repetitive sequences usually associated with mobile elements. It is likely that intronic ncORFs, which encode RTs and HEs, may have contributed to the enlarged mt genome of O. sinensis.

Volatiles from the xylarialean fungus Hypoxylon invadens.

Project description:The volatiles emitted by agar plate cultures of the xylarialean fungus Hypoxylon invadens were investigated by use of a closed loop stripping apparatus in combination with GC-MS. Several aromatic compounds were found that could only be identified by comparison to all possible constitutional isomers with different ring substitution patterns. For the set of identified compounds a plausible biosynthetic scheme was suggested that gives further support for the assigned structures.
