Pseudochromosome construction
To anchor the initial assembly to the chromosome level, a total of 0.69
Gb Hi-C sequencing data were used. Reads pairs are first independently
aligned on the reference genome, achieving a mapping ratio between 83%
and 89% (Table S1 ). The proportions of unique pairs, total
ratio of the multiple and singleton pairs, ratio of unmapping pairs is
58.28%, 39.43%, 2.29%, respectively (Figure S1 ). After
filter, the remaining pairs of valid reads is 122,392,006, about 40.18%
of the total. At last, the initial assembly was further anchored onto 24
chromosomes (Fig. 1a , b and c ), of which 8
chromosomes have telomeres at both ends, and only 2 chromosomes have 3
gaps in totally (Fig. 1b ).
