| Summary: | Snow-algae are a diverse group of extremophilic microeukaryotes found on melting polar and alpine snowfields. They play an important role in the microbial ecology of the cryosphere, and their propagation on snow and ice surfaces may in part accelerate climate-induced melting of these systems. High quality snow-algae genomes are needed for studies on their unique physiology, adaptive mechanisms and genome evolution under multiple forms of stress, including cold temperatures and direct sunlight. Here we assembled and annotated the genome of Limnomonas spitsbergensis, a cryophilic biciliate originally isolated from melting snow on Svalbard, in the Arctic. The L. spitsbergensis genome assembly is based primarily on the use of PacBio long reads and secondly Illumina short reads, with an assembly size of 260.248 MB in 124 contigs. A combination of three alternative annotation strategies were used including protein homology, RNA-seq evidence and PacBio full length transcript isoforms. The best merged set of ... |
