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.
对马铃薯线粒体(mt)tRNA(Leu)(NAA)及其细胞质(cyt)对应物进行测序后发现,除了转录后修饰外,这些tRNA是相同的:mt tRNA(Leu)的第18位是Gm,而不是cyt tRNA(Leu)中的G。杂交研究表明,马铃薯mt tRNA(Leu)(NAA)具有核起源,因此必须从细胞质中导入。
