Puccinia striiformis is a fungal species and plant pathogen. It causes stripe rust on wheat, but has other hosts as well. The species is common in Europe and in more recent years has become a problem in Australia.[2] Crop infections can cause losses of up to 40%, and the fungus will infect both winter wheat and spring wheat.[3]

Taxonomy
The taxonomy of P. striiformis was revised by Liu & Hambleton in 2010. These strains – commonly called stripe rusts of wheat and other grasses – were redefined as a sensu lato and separated into four species based on molecular and morphological studies: Puccinia striiformis sensu stricto (on Aegilops, Elymus, Hordeum and Triticum spp.), Puccinia pseudostriiformis (on Poa spp.), Puccinia striiformoides (on Dactylis glomerata, which Liu & Hambleton believe to generalize to all Dactylis) and Puccinia gansensis (a sp. nov. they find on Achnatherum inebrians).[4] P. striiformis, can greatly decrease wheat yield in northern Punjab and Khyber Pakhtunkhwa (NWFP).[citation needed]
