Communications Biology, Published online: 15 June 2026; doi:10.1038/s42003-026-10468-6Analysis of resequencing data from the dikaryotic fungus Puccinia striiformis f. sp. tritici identified two predominant nuclear haplotypes in the global pathogen population. Genomic evidence confirmed hybridization events within the population, which contributed to genetic diversity and provided new insights into the evolution of virulence.
