Abstract excerpt
Pentatricopeptide repeat (PPR) proteins compose a family of nuclear-encoded transcriptional regulators of cytoplasmic genes. They have shown dramatic expansion in copy number in plants, and although the functional importance of many remains unclear, a subset has been repeatedly implicated as nuclear restorers for cytoplasmic male sterility. Here we investigate the molecular population genetics and molecular...
