EMB2217 Is a Mitochondrial PPR‐SMR Protein Required for the Splicing of Multiple Group II Introns During Arabidopsis Development
Pentatricopeptide repeat (PPR) proteins are key regulators of the organellar RNA metabolism in plants. However, the functions of mitochondrial PPR proteins belonging to the subclass of P‐type PPR factors containing the SMR domain remain much less understood. Here, we characterize the EMBRYO DEFECTIVE 2217 (EMB2217/At1g...
