Fig. 4: Variation in Avr gene haplotypes in nuclear-phased Puccinia graminis f. sp. tritici (Pgt) genomes.
From: Allelic variation of Avr genes in highly virulent strains explains severe wheat stem rust epidemics
Schematic showing Avr gene variants encoded by haplotypes of the AvrSr13, AvrSr22, AvrSr27, AvrSr33, AvrSr35/50, AvrSr62 loci in Pgt isolates Pgt21, Ug99, ETH2013-1 and ITA2018-1. Nuclear haplotypes of each strain are shown at left. Genes are shown as arrows and numbers indicate variant designation. Blue denotes Avr variants recognized by the corresponding Sr gene in functional assays, while pink denotes unrecognized variants. Blue and pink striped arrows denote Avr variants which gave an intermediate response in functional assays. Light blue fill with dashed outline indicates recognized alleles with zero or very low expression. Triangles represent insertional mutants previously described in ref. 22. Gene IDs for Avr variants are provided in Supplementary Data 12.
