A nuclear‐encoded potato (Solanum tuberosum) mitochondrial tRNALeu and its cytosolic counterpart have identical nucleotide sequences

[摘要]

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.
