oenothera drummondii/arginine

The mRNA for subunit 9 of the ATPase (atp9) in the higher plant Oenothera is edited in four nucleotide positions. Three events alter genomic serine and proline codons to triplets specifying leucine. A UGA termination codon is introduced into the reading frame by modification of a CGA arginine codon.

The gene encoding ribosomal protein S14 (rps14) in Oenothera mitochondria is located upstream of the cytochrome b gene (cob). Sequence analysis of independently derived cDNA clones covering the entire rps14 coding region shows two nucleotides edited from the genomic DNA to the mRNA derived sequences
