A nuclear-encoded potato (Solanum tuberosum) mitochondrial tRNA(Leu) and its cytosolic counterpart have identical nucleotide sequences.
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.
