Other claims from this paper (8)
- Observation ZmMKK4 localized primarily to the nucleus and cytoplasm.
- Observation ZmMKK4 was highly expressed across multiple tissues including kernels.
- Intervention effect zmmkk4 knockout reduced or impaired kernel size.
- Intervention effect zmmkk4 knockout reduced or impaired weight.
- Intervention effect zmmkk4 knockout reduced or impaired kernel development.
- Observation Mutant kernels showed a decrease in starch content.
- Observation Mutant kernels showed a increase in protein content.
- Recommendation The authors present ZmMKK4 as a candidate for marker-assisted selection or gene editing.
