Fig. 5

Close-up of MIC1 displaying rapid domain recycling. The branches of the hotspot clade, the outer clade, and the ancestral clade are shown in red, blue, and cyan, respectively. Dots on the branches indicate a bootstrap support value ≥ 85%. Alongside the tree are cartoons of each protein, annotated with the domain(s) in the position that they appear in the protein (protein backbone, gray line; NB-ARC domain, black rectangle; LRR and AAA, TIR, and RPW8 domains, orange rectangles; other domains in different colors and shapes as indicated in the key). For clarity, the domain lengths are shown in the key for B3, Exo70, GRAS, and the Myb_DNA_binding domains. E-value cut-off for presence of an ID domain, 0.001; domains with e-value > 0.001 and ≤ 0.05 are shown as gray rectangles. E-value cut-off for an LRR, AAA, TIR, or RPW8 domain, 10.0
