Structures of tobacco chloroplast genes for tRNAIle (CAU), tRNALeu (CAA), tRNACys (GCA), tRNASer (UGA) and tRNAThr (GGU): a compilation of tRNA genes from tobacco chloroplasts

Abstract
The location and nucleotide sequences of tobacco chloroplast genes for tRNAIle (CAU), tRNALeu (CAA), tRNACys (GCA), tRNASer (UGA) and tRNAThr (GGU) (trnI-CAU, trnL-CAA, trnC-GCA, trnS-UGA and trnT-GGU, respectively) have been determined. The trnI and trnL are located in the inverted repeat region. The trnC, trnS and trnT are present in the large single copy region. These five tRNA genes together with the 25 different tRNA genes previously published have been compiled and compared. These 30 tRNA genes corresponding to 20 amino acids are most likely to be all of the tRNA genes encoded in tobacco chloroplast genome.
