Shaorui Tian; Changyun Liu; Jie Dong; et al. Molecular Plant Pathology 2026. doi:10.1111/mpp.70237
Other claims from this paper (8)
- Observation The coat protein of tobacco rattle virus interacts with Nicotiana benthamiana ferredoxin NbFd1 in chloroplasts.
- Mechanism The TRV coat protein recruits the 26S proteasome to promote NbFd1 degradation.
- Mechanism NbFd1 degradation reduces the net photosynthetic rate facilitated by NbFd1.
- Mechanism Reduced NbFd1-facilitated photosynthesis ultimately causes leaf chlorosis.
- Observation Evolutionary analyses indicate Fd1 originated from prokaryotic photosynthetic bacteria and was maintained in plants through endosymbiosis under strong selective pressure.
- Observation Fd1 from Selaginella moellendorffii, an early-diverging vascular plant, is also recognised by TRV CP, suggesting an ancient origin of the interaction.
- Observation Solanum lycopersicum Fd1 interacts with TRV CP.
- Intervention effect Overexpression of Solanum lycopersicum Fd1 suppresses TRV-GFP infection, supporting a defensive role.
