Other claims from this paper (10)
- Observation Different Berberis species were widely distributed in the surveyed regions.
- Observation Most surveyed Berberis plants had pycnia and aecia of rust fungi.
- Observation The survey identified 28 Berberis species.
- Intervention effect Eighteen of 20 tested Berberis species were susceptible to the wheat stripe rust pathogen in greenhouse tests.
- Observation Four aecia from naturally infected barberry produced stripe rust uredinia on wheat Mingxian 169.
- Observation Four barberry isolates had ITS sequences with 99% identity to reference stripe rust sequences.
- Observation The four barberry isolates had virulence patterns distinct from previously reported wheat races.
- Observation Single-uredinium isolates from barberry had virulence diversity rates of 9.0 to 28.1%.
- Observation The authors conclude that the stripe rust pathogen can infect some Berberis species naturally.
- Mechanism The authors suggest sexual reproduction on barberry may contribute to stripe rust diversity in China.
