Gene Details:

Functional Descriptions:

  • Null mutation of Smk4 slows plant growth and development, causing small plants, delayed flowering time, and small kernels.
  • Through characterizing a small kernel4 (Smk4) mutant, here we report the function of Smk4 and its role in maize growth and development.
  • Cloning revealed that Smk4 encodes a new E-subclass PPR protein, and localization indicated that Smk4 is exclusively localized in mitochondria.
  • Smk4 functions in the C-to-U editing of cox1-1489, and this editing is crucial for mitochondrial complex IV activity, plant growth, and kernel development in maize.
  • Smk4 encodes an E-subclass PPR protein that is targeted to mitochondria.
