Extended Data Fig. 4. Haplotype analysis leads to the designation of stem rust resistance gene Sr66.

Extended Data Fig. 4

a, Phylogeny showing the relationship across Mla genes from Ae. tauschii and barley. Resistance Gene Analogs (RGA) represent Ae. tauschii and Resistance Gene Homologs (RGH) represent barley cultivar Morex. The Ae. tauschii RGA gene sequences were derived from different accessions (Supplementary Table 10). RGA/RGH families 1, 2 and 3 are indicated in blue, red and green, respectively. The tree was constructed using the unweighted UPGMA algorithm. Bootstrap support values are shown based on 5,000 replicates. b, SrTA1662 (Sr66) and Sr33 display different race specificities. Reactions to Puccinia graminis f. sp. tritici isolates KE17c-21 (race TTKTF), IT16a-19 (TTRTF), and KE305b-17 (TTKSK) of transgenic SrTA1662 (Sr66) wheat lines and non-transgenic nulls (1 to 6) and wheat Sr gene introgression lines and controls (7 to 13). 1, Fielder null (DPRM0050); 2, Sr66 (DPRM0051); 3, Sr66 (DPRM0059); 4, Fielder null (DPRM0062); 5, Sr66 (DPRM0071); 6, Fielder null (DPRM0072); 7. Sr45 (RL5406); 8. Sr33 (RL5405); 9. Sr24 (LcSr24Ag); 10. Sr31 (Little Club/Agent (CI 13523)); 11. Sr39 (RL5711); 12. Sr33 (Chinese Spring); 13. cv. Morocco.
