Marasmius oreades genome assembly v2: Linkage map & repeat library

The fairy-ring mushroom Marasmius oreades can be used as a natural model system for mutation accumulation studies. During this project we constructed a genetic linkage map and used it for re-assembly of the M. oreades genome sequence. Genes and repeats were predicted in the genome, and a custom library of repetitive sequences was manually compiled and curated. In this repository we provide the linkage map and repeat library of the species.

Methods
The mapping population consisted of 95 haploid single-spore isolates originating from one individual. They were sequenced using Illumina HiseqX, and LepMAP3 was used to construct a genetic linkage map.

The genomic sequence v2 of Marasmius oreades (Maror2), was mined for repeat sequences. Each resulting sequence was BLASTed back to the genome and hits with flanking regions were aligned. Each alignment was manually inspected, consensus sequences for each repeat family were created and classified.

For the v. 2.2 of the repeat library, newly identified repeat families described in the study "Stage-specific transposon activity in the life cycle of the fairy-ring mushroom Marasmius oreades" (https://doi.org/10.1073/pnas.2208575119) were added.

v2.3: added another newly found hAT element (MarorhAT-13). Also updated the excel sheet.
