测定了烟草叶绿体tRNAPro（UGG）、tRNATrp、tRNAfMet和tRNAGly（GCC）基因的核苷酸序列。这些基因都不含内含子。一个不寻常的特征是tRNAGly在D茎中只包含两个碱基对（A-U, G-U）。这4个tRNA基因位于已知的烟草叶绿体DNA物理图谱中。对叶绿体tRNA的杂交分析表明，这四个tRNA基因在体内均有转录。
The nucleotide sequences of tobacco chloroplast genes for tRNAPro(UGG), tRNATrp, tRNAfMet and tRNAGly(GCC) have been determined. None of these genes contains an intron. One unusual feature is that the tRNAGly contains only two base-pairs (A-U, G-U) in the D stem. These four tRNA genes were located in the known physical map of tobacco chloroplast DNA. Hybridization analysis to chloroplast tRNA revealed that all four tRNA genes are transcribed in vivo.
