Chromosome rearrangement and splitting between P1609 and 70–15. a Bar plot showing the chromosomes in 70–15. b Bar plot showing the assembled contigs of P1609. Colinear chromosomes of 70–15 and contigs of P1609 are indicated by the same color. c Dual synteny plot showing splitting of Ctg2 of P1609 into chr. 4 and chr. 7 in 70–15. d PacBio long-read coverage from 2.02 to 2.94 Mb of Ctg 2. Color of reads indicate different read lengths.
