Other claims from this paper (13)
- Observation StRab5b amino acid had highest homology with NbRab5b in N. benthamiana.
- Observation StRab5b amino acid had lowest homology with StRab in potato.
- Observation StRab5b expression varied among potato tissues and varieties.
- Intervention effect P. infestans infection induced StRab5b expression.
- Intervention effect Silencing StRab5b facilitated pathogen infection in potato.
- Intervention effect Silencing the homologous gene facilitated pathogen infection in N. benthamiana.
- Intervention effect Stable StRab5b expression increased H 2 O 2 accumulation in infected potato leaves.
- Intervention effect Stable StRab5b expression increased ROS scavenging enzyme activity and expression in potato.
- Intervention effect Stable StRab5b expression attenuated P. infestans development in potato.
- Intervention effect Stable StRab5b expression reduced lesions on infected potato leaves.
- Intervention effect LOX transcripts rose rapidly after P. infestans inoculation.
- Intervention effect JA level rose rapidly after P. infestans inoculation.
- Mechanism The authors infer that StRab5b regulates potato late blight resistance through JA-mediated defense signaling.
