MIC1 has proliferated in grasses and continues to accumulate new domains as seen from comparison of wheat and its diploid progenitors. a Overall evolutionary relationship of grasses used in this study and corresponding number of NLR-IDs in MIC1. Key clade divergence is marked on the tree in millions of years as estimated at timetree.org. b The repertoires of IDs are different among wheat subgenomes and their progenitors suggesting continuous integration of new IDs
