Wheat stripe rust, caused by Puccinia striiformis Westend f. sp. tritici (PST), is one of the most devastating diseases of wheat (Triticum aestivum L.) worldwide, especially in wheat-growing areas with cool and moist environments. Stripe rust can cause severe yield losses owing to shriveled grain and weakened plant development (Roelfs et al. 1992).
In terms of area affected by stripe rust, China, especially southwest China, is one of the largest epidemic regions in the world (Chen 2005; Luo et al. 2005; Li et al. 2006). In recent years, stripe rust has become particularly devastating in that region owing to epidemics of physiological races ...
