A novel group II intron has been identified in the pea (Pisum sativum) mitochondrial genome. The gene harbouring this intron is identified as rps10 (encoding protein S10 of the small ribosomal subunit) by similarity to its known homologues in bacteria and in the mitochondrion of the liverwort Marchantia polymorpha. The rps10 gene is transcribed in pea, the intron is removed, and RNA editing in the rps10 reading frame increases similarity to its homologue in the M. polymorpha mitochondrion. Contrary to the situation in bacteria and Marchantia, rps10 is not part of a ribosomal-protein gene cluster in pea. It is flanked upstream by the genes trnF and trnP, encoding phenylalanine- and proline-accepting tRNAs, and downstream by cox1, encoding subunit 1 of the cytochrome-c-oxidase. Southern hybridization shows that sequences homologous to rps10 exist in potato mitochondria but not in mitochondria of Oenothera berteriana and Arabidopsis thaliana. The pea rps10 intron is homologous to introns in rrn26 and cox3 in the Marchantia mitochondrial genome, while the Marchantia rps10 gene lacks an intron.
