Other claims from this paper (7)
- Observation 3-Mercaptopropionic acid (3-MPA), a thiol compound, was detected in the metabolome of the supernatant of strain CHA0.
- Observation 3-MPA exhibited antibiotic activity against oomycete and fungal pathogens.
- Intervention effect 3-MPA suppressed Pythium damping-off and root rot in cucumber.
- Observation 3-MPA exhibited antibiotic activity without direct contact with pathogens, indicating a volatilization effect.
- Observation A homologous gene encoding 3-MPA dioxygenase was identified in the CHA0 genome.
- Intervention effect The 3mdo-negative mutant showed stronger growth inhibitory activity against oomycete and fungal pathogens and stronger plant protection efficacy than wild-type CHA0.
- Mechanism The authors conclude that 3-MPA is a biocontrol factor of strain CHA0.
