摘要: Chloroplast (cp) genomes of three land plants, namely tobacco, rice and Marchantia polymorpha, have now been completely sequenced. In tobacco (Fig. 1), the cp genome codes for 30 tRNA species (Shinozaki et al. 1986; Sugiura Wakasugi 1989), 23 being encoded by single genes (located in large copy (LSC) or small (SSC) regions), 7 present twice (in IR sequences). same set was found (Hiratsuka 1989). However, a total 31 are liverwort polymorpha genome; additional gene (with respect to rice) is tRNAAr9(CCG) (Ohyama al., 1986). Pseudogenes number genomes. For instance, pseudo-tRNAIIe pseudo-tRNATrP (El-Gewely 1984) Euglena gracilis strain bacillaris. A pseudo-tRNAPro with GGG anticodon has sequenced tRNAfMet/GIy chimeric structure described wheat (Howe 1985) pseudo-tRNAThr reported barley (Oliver Poulsen 1984), (Quigley Weil
