a Genome-wide distribution of heterozygosity in the Chinese Maotai-flavored liquor yeast MT1 genome. The frequency of the extracted heterozygosity was plotted using 10-kb windows of the chromosomal coordinates, where black vertical lines represent the division between two chromosomes. Heterozygous SNPs or Indels in MT1 are shown in red and blue, respectively. b Phylogenetic tree generated by Mega5 [51] using the whole genome sequence of MT1 and the available Saccharomyces cerevisiae genomes in NCBI. Different strains are represented in the diagrams by different shapes and colors. Red triangles, the typical Chinese liquor fermentation strain MT1; yellow triangles, sake yeast strain; red rhombuses, clinical strains; white circles, library strains; aqua circles, bioethanol strain; blue circles, wine strains from Europe; pink circles, wine strains from Italy; and dark cyan circles, beer strains. c Functional classification of the specific genes in MT1. d Functional classification of the genes lost from MT1
