Genome sequence resource of a Puccinia striiformis isolate infecting wheatgrass. Phytopathology. 109(9):1509-1512. https://doi.org/10.1094/PHYTO-02-19-0054-A. DOI: https://doi.org/10.1094/PHYTO-02-19-0054-A Interpretive Summary: Genome Sequence Resource of a Puccinia striiformis Isolate from Wheatgrass Associated with Stripe Rust on both Wheat and Barley Stripe rust is a disastrous disease of cereal crops and various grasses. Grasses are considered as reservoirs harboring more genetic variation of stripe rust pathogens compared with cereal crops. The stripe rust fungus on grasses is thus presumed to be the origin of different forms attacking wheat, barley, and some grasses. To date, fourteen stripe rust genomes are publicly available, including thirteen wheat stripe rust isolates and one barley stripe rust isolate. In this study, one isolate of the stripe rust fungus collected from wheatgrass was sequenced, assembled, and annotated. The draft genome of the isolate is a valuable resource in shedding light on the evolution and pathogenicity of the stripe rust pathogen. The genome sequences will be useful for studying pathogen virulence genes. Technical Abstract: Stripe rust caused by Puccinia striiformis is a disastrous disease of cereal crops and various grasses. Grasses are considered as reservoirs harboring more genetic variation of stripe rust pathogens compared with cereal crops. The P. striiformis fungus on grasses is thus presumed to be the origin of different formae speciales. To date, fourteen stripe rust genomes are publicly available, including thirteen P. striiformis f. sp. tritici and one P. striiformis f. sp. hordei. In this study, one isolate (11-281) of P. striiformis collected from wheatgrass was sequenced, assembled, and annotated. The draft genome of the isolate is a valuable resource in shedding light on the evolution and pathogenicity of P. striiformis. |
