AB  - The chloroplast genome of 5959 species was analyzed to construct the anticodon 
      table of the chloroplast genome. Analysis of the chloroplast transfer ribonucleic 
      acid (tRNA) revealed the presence of a putative quadruplet anticodon containing 
      tRNAs in the chloroplast genome. The tRNAs with putative quadruplet anticodons 
      were UAUG, UGGG, AUAA, GCUA, and GUUA, where the GUUA anticodon putatively 
      encoded tRNA(Asn). The study also revealed the complete absence of tRNA genes 
      containing ACU, CUG, GCG, CUC, CCC, and CGG anticodons in the chloroplast genome 
      from the species studied so far. The chloroplast genome was also found to encode 
      tRNAs encoding N-formylmethionine (fMet), Ile2, selenocysteine, and pyrrolysine. 
      The chloroplast genomes of mycoparasitic and heterotrophic plants have had heavy 
      losses of tRNA genes. Furthermore, the chloroplast genome was also found to 
      encode putative spacer tRNA, tRNA fragments (tRFs), tRNA-derived, stress-induced 
      RNA (tiRNAs), and the group I introns. An evolutionary analysis revealed that 
      chloroplast tRNAs had evolved via multiple common ancestors and the GC% had more 
      influence toward encoding the tRNA number in the chloroplast genome than the 
      genome size.
