Sexual populations of the stem rust pathogen (Puccinia graminis or Pg) are producing new race types globally. An analysis of 385 Pg genomes (204 from this study) illuminated international migration and admixture events. Within Kazakhstan, a novel and diverse sexual clade of P. graminis is described. An analysis of the highly divergent mating type homeodomain (HD) locus found that the 75…
