A gene isolated from one of the earliest cultivated wheat species, Einkorn wheat (Triticum monococcum), confers resistance to a deadly version of stem rust, scientists report June 27 in Science. A second gene found in the wild grass Aegilops tauschii, a botanical parent of today’s bread wheat (T. aestivum), also helps bread wheat fight the fungus, another research team reports. 

Both genes are thought to help wheat reco
