Title
Identification and characterization of PsFwC9 conferring Fusarium Wilt Resistance in Pea
Dong Deng; Wenqi Wu; Canxing Duan; et al. Horticulture Research 2026. doi:10.1093/hr/uhag166
Other claims from this paper (9)
- Observation A novel resistance gene PsFwC9 conferring resistance to Fop race 5 was identified in the resistant pea pure line Chengwan 9-8 (CW9-8).
- Observation Genetic analysis of the F2 population from the resistant CW9-8 by susceptible CW9-1 cross showed PsFwC9 was controlled by a single dominant gene.
- Observation PsFwC9 was localized by resequencing, BSA-seq and fine mapping to an 817.06 kb region on chromosome 4 flanked by KASP markers A016508 and A016511.
- Association Haplotype analysis showed that only marker A016615 was significantly associated with Fusarium wilt resistance.
- Observation Marker A016615 was designated as a diagnostic marker for PsFwC9.
- Observation Quantitative real-time PCR showed no significant difference in Psat4g213640 expression between CW9-8 and CW9-1.
- Intervention effect Overexpression of Psat4g213640CW9-8 in the hairy root system significantly enhanced the resistance of CW9-1 to Fusarium wilt.
- Intervention effect RNA interference-mediated silencing of Psat4g213640CW9-8 reduced the resistance of CW9-8 to Fusarium wilt.
- Observation Subcellular localization showed that the protein encoded by Psat4g213640 was targeted to the endoplasmic reticulum.
