Other claims from this paper (6)
- Observation Pm12, Pm16, Pm21 and Pm37 resisted all isolates.
- Observation Nine genes resisted over 80% of isolates.
- Observation Eleven other genes were ineffective, with susceptibility to 37–97% of isolates.
- Observation Sequencing four pathogen genes in 116 isolates yielded only four informative SNPs.
- Observation Linkage disequilibrium suggested frequent pathogen recombination.
- Observation Virulence networks showed no genetic subdivision, suggesting a panmictic population.
