During the last decade the disease affected the crops in West Siberia. The plant response to infection is determined by the correspondence of host resistance (Sr) and fungus avirulence/virulence (Avr/vr) genes. We first characterized the West Siberian population of wheat stem rust: the probable sources of infection were traced, the race composition and main avirulence genes were defined. Four fungal lines with contrasting patterns of Avr genes were selected for whole genomic sequencing.
