Abstract excerpt
Plant mitochondrial genomes lack a number of tRNA genes and the corresponding tRNAs, which are nuclear-encoded, are imported from the cytosol. We show that specific import of tRNA(Gly) isoacceptors occurs in tobacco mitochondria: tRNA(Gly)(UCC) and tRNA(Gly)(CCC) are cytosolic and mitochondrial, while tRNA(Gly)(GCC) is found only in the cytosol. Exchange of sequences between tRNA(Gly)(UCC) and tRNA(Gly)(GCC)...
