Other claims from this paper (8)
- Observation Pyraclostrobin showed strong antifungal activity against Fol, with an average EC50 of 0.3739 ± 0.2413 μg/mL over 100 strains.
- Observation Four of five chemically tamed Fol mutants showed high-level resistance to pyraclostrobin due to the Cytb-G143S mutation.
- Observation One Fol mutant showed medium-level resistance to pyraclostrobin due to the Cytb-G137R mutation.
- Mechanism Molecular docking indicates that the Cytb-G143S or Cytb-G137R mutations decrease the affinity of Cytb for pyraclostrobin.
- Association Resistant Fol mutants show reduced mycelial growth, virulence and sporulation.
- Intervention effect Mutants carrying the Cytb-G143S mutation suffer a more severe fitness penalty than those carrying the Cytb-G137R mutation.
- Association Resistance to azoxystrobin, picoxystrobin, fluoxastrobin and pyraclostrobin is positively correlated among resistant mutants.
- Observation The potential risk of Fol resistance development to pyraclostrobin is low to moderate.
