    This dataset includes 1838 SNP loci of 26 isolates of the wheat stem rust fungus, Puccina graminis f .sp. tritici. This data was used to assess the genetic relationship of a unique fungal isolate (18SPA092-1, race TKHBK) derived from a wheat stem rust sample collected in Spain in 2018 with a set of 25 reference isolates from previously defined genetic clades. Results indicate that isolate 18SPA092-1 had a unique multilocus genotype and constitutes a previously unknown lineage. Data is being released now in conjunction with publication of a primary research paper that describes this work.

    SNP data of 56 Kazakhstani and 23 reference isolates of the wheat stem rust fungus, Puccinia graminis f. sp. tritici
    (2022-03-09) Olivera Firpo, Pablo; Szabo, Les J; Kokhmetova, Alma; Morgunov, Alexey; Luster, Douglas; Jin, Yue; oliv0132@umn.edu; Olivera Firpo, Pablo, D; Wheat stem rust research project | USDA ARS Cereal Disease Lab and University of Minnesota
    This dataset includes 2310 SNP loci of 79 isolates of the wheat stem rust fungus, Puccina graminis f .sp. tritici (Pgt). This data was used to assess the genetic diversity of a Pgt population (56 isolates) from Kazakhstan derived from stem rust samples collected in 2015-2017 wheat growing seasons. Twenty-three reference isolates from previously defined genetic clades were included in the analysis. Results indicate that the Pgt population form Kazakhstan is highly diverse and most of the isolates are of sexual origin. Data is being released now in conjunction with publication of a primary research paper that describes this work.
