Fine mapping of the wild emmer-derived powdery mildew resistance Pm36 locus using homozygous backcross inbred lines (BILs) of durum wheat. (a) Physical location of Pm36 on the 5BL chromosome arm (bin 5BL_1) (blue block); (b) Genetic map of the 5BL region harboring Pm36 with the genetic position (cM) of relevant SNP markers according to the consensus durum map [44]; (c,d) Schematic representation of the durum wheat Svevo reference genome (grey block) [45] and the dicoccoides Zavitan reference genome v2.0 (red block) [46] with the physical position (Mb) of relevant SNP markers; (e) Genotype and phenotype of four BILs (5BIL-50, 5BIL-29, 5BIL-20, 5BIL-42). S and R on the right of the bars indicate susceptible and resistant phenotype, respectively. Gray and red rectangles represent the genotypes of the PM-susceptible durum wheat Latino and the PM-resistant lines, respectively. Pm36 was placed within a 7.3 cM interval flanked by IWB55478 and IWB22904 (between two vertical lines) based on the genotypes of the BILs at the marker loci and their PM phenotypes.
