Genomic resources of Cold-adapted Mrakia yeasts and their potential biotechnological applications.

ABSTRACT: Mrakia is a cold-adapted yeast genus commonly found in polar environments, including the Antarctic and Arctic regions. Several Mrakia genome sequences have been reported to date; however, comprehensive genomic analyses remain limited. Further, there are no reports of complete mitochondrial genome sequences for the genus Mrakia. Therefore, we isolated two cold-adapted yeast strains, Mrakia gelida PAMC 26583 and Mrakia robertii PAMC 26600, from Arctic lichens. Phylogenetic analysis placed both strains within the order Cystofilobasidiales. High-quality whole-genome assemblies were generated using Nanopore long-read and Illumina short-read sequencing, resulting in nearly complete nuclear and mitochondrial genomes. Analyses of gene family expansion and contraction revealed lineage-specific enri
