Evolutionary model of R-genes in plant genomes. Major conclusions from the current study are schematically illustrated in four panels highlighting (A) biased deletion of R-genes between duplicated blocks (D for dominant and S for sensitive) after whole genome duplication; (B) R-genes shuffling via transposition as well as clusterization involving R-gene/miRNA interactions; (C) R-genes domains rearrangement in clusters considered as recombination hotspots; (D) Presence/Absence Variation (PAV) and Copy Number Variation (CNV) between related species. R-gene classes are illustrated according to the color code at the top left. Shuffling events are illustrated through the color code at the top right.
