The trends in the spread of simple sequence repeats in the genomes of Schizophyllum commune.
Due to their high number and variety, simple sequence repeats in DNA are a valuable source of genetic markers widely used in population genetics, genetic diversity, and fingerprinting. Schizophyllum commune is a cosmopolitan basidiomycete and a valuable object for biotechnology and mycology. It is often used as a model organism in genetic and population studies. Numerous genome sequences of S. commune are available in the National Center for Biotechnology Information (NCBI) database, allowing for a meticulous study of the distribution of simple tandem nucleotide repeats in the genomes of different strains, based on their origin. Analysis of the average density of simple tandem repeats in the genomes of S. commune fungi reveals the division of cultures into groups based on the USA, Ru (Russian Federation), and EA (South Korea, Japan, China) populations. Intensive point mutations lead to the accumulation and dominance of mononucleotide (C)n and dinucleotide (CG)n motifs in fungal genomes. Results show that the GCT motif contributes more to the divergence of the Ru population, whereas CTC, GAG, and GGA motifs contribute to the divergence of the USA population. Strains MG53 (China) and IUM1114-SS01 (South Korea: Incheon) from the EA population occupy a separate position, mainly because of the CGA motif. The divergence in quantitative traits of motifs between populations provides evidence of the evolutionary transformation of fungal genomes under environmental factors.
期刊介绍:
International in coverage, Mycologia presents recent advances in mycology, emphasizing all aspects of the biology of Fungi and fungus-like organisms, including Lichens, Oomycetes and Slime Molds. The Journal emphasizes subjects including applied biology, biochemistry, cell biology, development, ecology, evolution, genetics, genomics, molecular biology, morphology, new techniques, animal or plant pathology, phylogenetics, physiology, aspects of secondary metabolism, systematics, and ultrastructure. In addition to research articles, reviews and short notes, Mycologia also includes invited papers based on presentations from the Annual Conference of the Mycological Society of America, such as Karling Lectures or Presidential Addresses.
