As key regulators, pentatricopeptide repeat proteins (PPRs) function in ribonucleic acid (RNA) editing, organellar gene expression, photosynthesis, the organellar electron transport chain, cellular metabolism, and adenosine Triphosphate (ATP) production. Deficiencies in the functions of PPRs often result in organelle dysfunction, defects in growth and embryo development, or abnormal stress sensitivity. However, the role of PPRs in disease resistance in kiwifruit remains unclear, and the underlying role of RNA editing is not fully understood.
