Other claims from this paper (11)
- Observation Both resistant and susceptible Bletilla striata plants developed rust spores by 2 days post-inoculation.
- Association The resistant Bletilla striata accession showed significantly slower progression of spore stack formation and lesion expansion than susceptible plants.
- Association Rust-resistant Bletilla striata accessions showed faster and stronger defense responses to pathogen infection than susceptible plants.
- Association Rust-resistant Bletilla striata accessions showed significant upregulation of DEGs associated with antioxidant defense systems.
- Association Rust-resistant Bletilla striata accessions showed significant upregulation of DEGs associated with secondary metabolite biosynthesis.
- Association Rust-resistant Bletilla striata accessions showed significant upregulation of JA, SA and BR signaling pathway DEGs.
- Association Rust-resistant Bletilla striata accessions showed downregulation of DEGs involved in cell wall remodeling.
- Association Rust-resistant Bletilla striata accessions showed downregulation of calcium-mediated signaling.
- Intervention effect Rust pathogen inoculation enhanced chitinase activity in resistant Bletilla striata.
- Intervention effect Rust pathogen inoculation led to early accumulation of osmolytes in resistant Bletilla striata.
- Association The coordinated molecular and biochemical responses of Bletilla striata restricted pathogen colonization and spread.
