Sequencing of potato mitochondrial (mt) tRNA Leu (NAA) and of its cytosolic (cyt) counterpart revealed that these tRNAs are identical, except for a post‐transcriptional modification: a Gm is present at position 18 in mt tRNA Leu , instead of a G in cyt tRNA Leu . Hybridization studies have shown that potato mt tRNA Leu (NAA) has a nuclear origin and must therefore be imported from the cytosol.
