Genome Mapping. First circle: the outermost circle is the genome sequence position coordinates; Second circle: genomic GC content: the GC content is counted with a window of 200,000 bp and a step of (200,000) bp. The inward l blue part indicates that the GC content of this region is lower than the average GC content of the whole genome, the outward purple part is the opposite, and the higher the peak indicates a greater difference from the average GC content; Third circle: genomic GC skew value: window (200,000) bp, step (200,000) bp, the specific algorithm is GC/G + C, the inward green part indicates that the content of G in the region is lower than the content of C, the outward pink part is the opposite; The fourth–seventh circle: Gene density (with a window of 200,000 bp and a step length of 200000 bp to count the gene density of coding genes, rRNA, snRNA, tRNA respectively, the darker the color, the greater the density of genes within the window); Innermost circle: donors and acceptors of segmental duplications on fungus chromosomes are connected by purple lines.
