Other claims from this paper (12)
- Observation Two functional QS circuits, CepI/R and BviI/R, synthesize distinct AHL molecules, with C10-HSL dominant
- Observation Both synthases in CBMB40 contributed to production of N-hexanoyl (C6) and N-octanoyl (C8) homoserine lactones
- Observation The bviI synthase contributed to production of C10-HSL and N-dodecanoyl (C12) homoserine lactones
- Observation AHLs produced by CBMB40 could be detected in plant tissues
- Observation AHLs served as interpopulation signaling molecules within the rhizosphere
- Intervention effect The AHL-deficient mutant exhibited an extended log phase compared with the wild type
- Intervention effect The AHL-deficient mutant showed reduced protease activity
- Intervention effect The AHL-deficient mutant lost antagonism against Erwinia carotovora subsp. carotovora
- Intervention effect The AHL-deficient mutant showed diminished activity against multiple fungal pathogens
- Intervention effect Adding AHL extracts from the wild-type strain restored antagonistic activity in the mutant
- Mechanism In potato tuber assays, AHL-mediated QS was essential for the biocontrol potential of CBMB40
- Mechanism In pot culture in red pepper, AHL-mediated QS was essential for the biocontrol potential of CBMB40
