Misconception of Schizophyllum commune strain 20R-7-F01 origin from subseafloor sediments over 20 million years old.

ABSTRACT: Hole C0020A during Ocean Drilling Expedition 337 is the deepest hole in scientific ocean drilling (depth of 2466 m below the seafloor). The presence of microbial and fungal communities serves as firm evidence for life within sediments. The isolated from the core and cultivable in the laboratory strain S. commune 20R-7-F01, which has existed in a deep subseafloor environment for over 20 million years, is being considered a high-quality genome model for studying its evolution and environmental adaptation mechanism. We questioned the origin of the strain from the sediments using high mutagenic simple sequence repeats of DNA. The full genome analysis of mono-, di-, tri-, and tetra-motifs of DNA revealed no regularities in the quantitative distribution of motifs in different S. commune genomes.
