a, The genomic features of E. ferox (pseudomolecules size: 721.2 Mb) and C. demersum (pseudomolecules size: 703.8 Mb). From inside to outside: GC content in 500-bp sliding windows (i; minimum–maximum, 0.2–0.8); repeat density in 10-kb sliding windows (ii; minimum–maximum: 0–1.0, coloured from white to dark green); gene density in 100-kb sliding windows (iii; minimum–maximum, 0–30, coloured from white to dark orange); and SNV density in 100-kb sliding windows (iv; minimum–maximum: 0–0.025). The links in the centre connect syntenic gene blocks that were detected using MCscan. Chr, chromosome. b, Distribution of average synonymous substitution levels (Ks) between syntenic blocks after evolutionary rate correction. c, Syntenic blocks (involving ≥10 colinear genes) between genomes. The corresponding median Ks value is shown for each block, and polyploidization events are represented by different colours.
