Genome Size Estimation
87,165,732,691 bp Illumina clean reads were used to estimateG.
przewalskii genome size. The K-mer analysis result showed that three
peaks arised in the depth distribution curve of 17-mers are 20, 40, 80,
respectively. The different depth peak is representative of different
genome size. Because G. przewalskii is
autotetraploid,
the peak is representative of tetraploid, diploid, haploid genome size,
respectively. So 949,878,192 bp is haploid genome size of G.
przewalskii genome size (Figure S1 and Table S4).
