Telomere-to-telomere genome assembly of matsutake (Tricholoma matsutake).
Here, we report the first telomere-to-telomere genome assembly of matsutake (Tricholoma matsutake), which consists of 13 sequences (spanning 161.0 Mb) and a 76 kb circular mitochondrial genome. All the 13 sequences were supported with telomeric repeats at the ends. GC-rich regions are located at the middle of the sequences and are enriched with long interspersed nuclear elements (LINEs). Repetitive sequences including long-terminal repeats (LTRs) and LINEs occupy 71.6% of the genome. A total of 21,887 potential protein-coding genes were predicted. The genomic data reported in this study served not only matsutake gene sequences but also genome structures and intergenic sequences. The information gained would be a great reference for exploring the genetics, genomics, and evolutionary study of matsutake in the future, and ultimately facilitate the conservation of this vulnerable genetic resource.
期刊介绍：
DNA Research is an internationally peer-reviewed journal which aims at publishing papers of highest quality in broad aspects of DNA and genome-related research. Emphasis will be made on the following subjects: 1) Sequencing and characterization of genomes/important genomic regions, 2) Comprehensive analysis of the functions of genes, gene families and genomes, 3) Techniques and equipments useful for structural and functional analysis of genes, gene families and genomes, 4) Computer algorithms and/or their applications relevant to structural and functional analysis of genes and genomes. The journal also welcomes novel findings in other scientific disciplines related to genomes.
