a Venn diagram shows the shared and unique gene families among RUF, NIV, and SAT. b Expansion and contraction of gene families among RUF, NIV, SAT, and MER. Phylogenetic tree was constructed based on 10,206 high-quality 1:1 single-copy orthologous genes using MER as outgroup. Bar plot beside or on each branch of the tree represents the number of gene families undergoing gain (green) or loss (red) events. Lineage-specific and -extinct families are colored in orange and light blue, respectively. Number at the tree root (23,755) denotes the total number of gene families predicted in the most recent common ancestor (MRCA). The numerical value below phylogenetic tree shows the estimated divergent time of each node (MYA; million years ago). c Comparisons of disease-resistant genes among RUF, NIV, and SAT.
