Heatmap and dendrogram of wild-type isolate 11–281 and its mutants of Puccinia striiformis f. sp. tritici based on infection types (ITs). The virulence characterization of all isolates was conducted on the 18 wheat Yr single-gene differentials [48]. ITs 1 to 8 were transformed to the color key ranging from green to red, which indicate avirulent (resistant) to virulent (susceptible) reactions
