Other claims from this paper (8)
- Observation The P. brassicae effector PbCBM1 suppresses INF1/BAX-induced cell death.
- Intervention effect Arabidopsis overexpressing PbCBM1 showed significantly elevated susceptibility to P. brassicae.
- Intervention effect The Arabidopsis phb3 mutant showed increased susceptibility to P. brassicae.
- Observation AtPHB3 was identified as an interactor of PbCBM1 in vivo and in vitro in Arabidopsis.
- Intervention effect PbCBM1-overexpressing plants reduced salicylic acid pathway gene expression upon chitin treatment.
- Observation PbCBM1 competes with AtICS1 for AtPHB3 binding in Arabidopsis.
- Mechanism P. brassicae effector PbCBM1 disrupts the AtPHB3-AtICS1 complex and thereby suppresses salicylic acid biosynthesis and immunity in Arabidopsis.
- Recommendation The authors suggest that the PbCBM1-AtPHB3 pathway provides potential targets for breeding clubroot-resistant rapeseed varieties.
