*Genomes with low assembly quality are excluded from this analysis due to technical reason (see Methods).

#Post-y ploidy level.

Species-wise comparison of retained ohnolog duplicates gene pairs among NB-LRR loci, shown for seven species*. Genomes with below-threshold mean and median scaffold size (N50 ~ 50 kb) are excluded from this analysis due to technical reasons.
