  1. Contingency table of discovered NLR tandems (head-to-head gene pairs within 15-kbp distance). Top: tandems involving NLR-IDs; bottom: tandems involving members of MIC1
  2. MIC1- NLR-ID/NLR tandems generally consist of a MIC1-NLR-ID and a non-MIC1 NLR
  3. aA. tauschii and S. bicolor have the only NLR-ID/NLR-ID tandems
  4. bT.aestivum has one intra-MIC1 (outer clade) NLR/NLR tandem
  5. cT. aestivum has the only NLR/NLR-ID tandem with the NLR (and not the NLR-ID) being a member of MIC1
