Reciprocal crosses between wheat- and barley-adapted Puccinia striiformis isolates on Berberis vulgaris yielded 18 viable aeciospore-derived progeny despite strong host specialization and genome-wide differentiation.
- Why it matters: Host specialization can limit gene flow in fungal pathogens, but it is unclear whether sexual compatibility can persist when mating occurs on a shared alternate host.
- What they did: Wheat-adapted P. striiformis f. sp. tritici and barley-adapted P. striiformis f. sp. hordei were crossed on Berberis vulgaris, and chromosome-scale assemblies were used to map HD and PR mating-type loci.
- The result: Progeny inherited HD haplotypes from both parents in all four parental combinations and showed host-interaction profiles distinct from either parent, including compatibility with selected wheat and barley genotypes.
