Phylogenetic Relationship and NLR Repertoires of the Plant Species Used in This Study.
(A) Boxplot showing the variation in number of NB-ARC domains across Amborellales (n = 1), monocot (n = 42), and eudicot (n = 60) genomes available on Phytozome, Ensembl Plants or CoGe.
(B) Histogram of numbers of NB-ARC domains identified in angiosperm genomes.
(C) Species tree of monocot and eudicot genomes of interest. Number of NLRs with all 6 characteristic NLR amino-acid motifs annotated in each species are displayed in line with the species Latin name. Number of NLRs identified by PfamScan and the plant_rgenes pipeline are in parentheses. Black/red numbers on branches indicate the number of gained/lost NLRs.
