Genome sequencing of 14 Pseudogymnoascus strains. Pseudogymnoascus

Geomyces pannorum is a haploid, asexual fungus which can tolerate low temperature and high salinity conditions. We extracted 14 individuals from permafrost and from temperate environments and obtained de novo draft assembly for each of them. Comparative genome analysis reveals extremely high nucleotide diversity (~0.5 synonymous substitutions between individuals) and also reveals certain regions with phylogenetic pattern different from the rest of the genome.

泛生地霉（Geomyces pannorum）是一种单倍体无性真菌，可耐受低温与高盐环境。我们从永久冻土及温带环境中采集了14个菌株个体，并为每个个体完成了从头组装的草图基因组。比较基因组分析结果显示，该物种具有极高的核苷酸多样性（个体间同义替换率约为0.5），同时还发现基因组中存在部分区域的系统发育模式与基因组其余区域存在显著差异。
