Summary Rmg8 and Rmg7 are genes for resistance to the wheat blast fungus ( Pyricularia oryzae ), located on chromosome 2B in hexaploid wheat and chromosome 2A in tetraploid wheat, respectively. AVR‐Rmg8 , an avirulence gene corresponding to Rmg8 , was isolated from a wheat blast isolate through a map‐based strategy. The cloned fragment encoded a small protein containing a putative signal peptide. AVR‐Rmg8 was recognized not only by Rmg8 , but also by Rmg7 , suggesting that these two resistance genes are equivalent to a single gene from the viewpoint of resistance breeding.
