Genome Sequence Resource of a Puccinia striiformis Isolate Infecting Wheatgrass.

Stripe rust caused by Puccinia striiformis is a disastrous disease of cereal crops and various grasses. To date, 14 stripe rust genomes are publicly available, including 13 P. striiformis f. sp. tritici and 1 P. striiformis f. sp. hordei. In this study, one isolate (11-281) of P. striiformis collected from wheatgrass (Agropyron cristatum), which is avirulent to most of standard differential genotypes of wheat and barley, was sequenced, assembled, and annotated. The sequences were assembled to a draft genome of 84.75 Mb, which is comparable with previously sequenced P. striiformis f. sp. tritici and P. striiformis f. sp. hordei isolates. The draft genome comprised 381 scaffolds and contained 1,829 predicted secreted proteins. The high-quality draft genome of the isolate is a valuable resource in shedding light on the evolution and pathogenicity of P. striiformis.
