The project has established vast genomic resources for investigating how pathogens can adapt to attack a major crop. Considering both local scales (individual fields) and continental, as well as nuclear and mitochondrial genomic diversity, we have gained the following insights:
- Individual wheat fields can be colonized by massively diverse pathogen gene pools. The extent of genetic diversity suggests that the studied wheat pathogen is largely unhindered to adapt to individual wheat varieties.
- We identified genomic signatures indicating what mutations were particularly relevant to attack wheat varieties.
- At the continental scale, we find that the pathogen experienced severe bottlenecks to colonize more isolated regions including Oceania. Gene flow in Europe is extensive challenging traditional quarantine measures.
- Analysis of the mitochondrial genome reveals an unexpectedly high diversity that might be relevant for adaptation.
