Extended Data Fig. 7: Synteny plots showing the alignment of the Ku123 de novo genome assembly with the B73 and M017 reference genomes for every chromosome.

Extensive duplication in Mo17 on chromosome 6 corresponds to an expansion of 45S rDNA arrays. Ku123-specific large insertions on chromosomes 1, 3, 5, 6, 7 and specific to M017 on chromosome 8 correspond to knob insertions (see Extended Data Fig. 4). The position of the markers used for recombination frequency (c1, sh1 and wx1 on chromosome 9 and ws3, lg1 and gl2 on chromosome 2) are indicated by black tick marks on the Ku123 respective chromosomes.
