Recent progress in large-scale sequencing, genomics, and rapid gene isolation techniques has accelerated the identification of race-specific resistance (R) genes and their corresponding avirulence (Avr) genes in wheat, barley, rye, and their wild relatives. Here, we describe the growing repertoire of identified R and Avr genes with special emphasis on novel R gene architectures, revealing that there is a large diversity of proteins encoded by race-specific resistance genes that extends beyond the canonical nucleotide-binding domain leucine-rich repeat proteins. Immune receptors with unique domain architectures controlling race-specific resistance possibly reveal novel aspects on the biology of host–pathogen interactions. We conclude that the polyploid cereal genomes have a large evolutionary potential to generate diverse types of resistance genes.
