Other claims from this paper (7)
- Observation Mahonia fortunei, M. eurybracteata subsp. ganpinensis and M. sheridaniana were identified as alternate hosts for P. striiformis f. sp. tritici.
- Observation Seven Mahonia species were highly resistant to the rust pathogen.
- Observation Seven samples of P. striiformis f. sp. tritici were recovered from naturally rusted Mahonia cardiophylla plants.
- Observation SNP analysis showed high phenotype diversity (H = 0.32) among all SU isolates.
- Observation SU isolates had a high Shannon’s information index (I = 0.49).
- Observation Linkage disequilibrium analysis gave an insignificant rbarD value (0.003, P < 0.1).
- Mechanism All SU isolates are sexually produced, suggesting the rust parasitizes susceptible Mahonia to complete sexual reproduction under natural conditions.
