Ug99 has been recognized as a major threat to world wheat production. First detected in Uganda in 1998,it has now spread throughout East Africa, Yemen, Sudan and Iran. Its further predicted spread toward North Africa, Middle East, and Asia and beyond has raised serious concerns of major epidemics that could destroy the wheat crop in various areas. Detection of two new Ug99 variants in Kenya in 2006 and 2007 shows that Ug99 is evolving.
