Extended Data Fig. 5. Yr27 haplotype analysis, diversity, and homology modelling.

Extended Data Fig. 5

a, Polymorphic residues encoded by Yr27 alleles present in various wheat cultivars. Blue asterisks indicate residues that are polymorphic between Lr13 and Yr27. Functional motifs are indicated in different colors. b, Shannon entropy plot showing amino acid diversity across Yr27 based on the alignment of 20 different haplotypes. c, Yr27-specific KASP marker tested on Yr27 positive, Yr27 negative and heterozygous wheat plants (Avocet 2B x Avocet S F2 population). d, Yr27 model superimposed to the Arabidopsis thaliana RPP1-ATR1 cryo-EM structure. The close-up view shows the RPP1-ATR1 contact interface in the LRR domain. The labeled residues are the ones that were polymorphic between Lr13 and Yr27. The three residues Q871, N895 and T899 are predicted to locate on the inner surface of the LRR domain and the corresponding residues in RPP1 have been shown to form polar interactions with the ATR1 effector (indicated by green dashed lines).
