This study analyzes population dynamics and virulence-associated loci in the oat crown rust fungus using genomic and phenotypic data from isolates in the USA and South Africa.

The paper shows that the Ug99 wheat stem rust pathogen emerged through somatic hybridisation and nuclear exchange between dikaryons, with one haploid nucleus genotype shared with an older African lineage.

This study presents haplotype-phased genome assemblies of two dikaryotic Puccinia coronata f. sp. avenae isolates, revealing structural variation and heterozygous SNPs, and identifies co-expressed effector candidates associated with virulence differences.
