Other claims from this paper (9)
- Intervention effect Homozygous CRISPR-edited PMR4 orthologs in Brassica napus conferred resistance to powdery mildew and clubroot.
- Intervention effect Plasmodiophora brassicae infection induced callose deposition in Arabidopsis roots in a PMR4-dependent manner.
- Intervention effect Plasmodiophora brassicae infection induced callose deposition in Brassica napus roots in a PMR4-dependent manner.
- Intervention effect The pmr4-1 mutation did not affect primary infection by Plasmodiophora brassicae in Arabidopsis.
- Intervention effect The pmr4-1 mutation blocked pathogen entry from epidermal cells to the stele in a jasmonic acid signaling-dependent manner in Arabidopsis.
- Association Blocked pathogen entry in pmr4-1 coincided with accumulation of lignin-like and suberin compounds in periderm cell walls of Arabidopsis.
- Mechanism PMR4-encoded callose synthase is a host susceptibility factor facilitating secondary infection by Plasmodiophora brassicae.
- Recommendation PMR4 is a gene-editing target for enhancing resistance to powdery mildew and clubroot in Brassicaceae crops.
- Observation PMR4 was identified as a potential host susceptibility factor in Arabidopsis and Brassica napus.
