Abstract

The nucleotide sequences of tobacco chloroplast genes for tRNA(Gly) (UCC) and tRNA(Arg) (UCU) have been determined. The tRNA(Gly) gene has a 691-base-pair intron located in the D stem while the tRNA(Arg) gene does not have any intron. The tRNA(Gly) and tRNA(Arg) genes are encoded on the same strand and separated by a 169-base-pair spacer. The tRNA(Gly) gene is transcribed as a 900-base precursor RNA molecule. The tRNA(Gly) and tRNA(Arg) deduced from the DNA sequences show 84% and 55% sequence homologies with Escherichia coli tRNA(Gly) (UCC) and phage T4 tRNA(Arg) (UCU), respectively.
