Nucleotide sequence of a 1.1 kb fragment of the pea chloroplast genome containing three tRNA genes, one of which is located within an open reading frame of 91 codons

Abstract

The nucleotide sequence of a 1082 bp fragment from the pea (Pisum sativum) chloroplast genome is presented. This fragment contains genes for tRNAGlu, tRNATyr and tRNAAsp as well as an open reading frame (ORF) of 91 codons on one strand and two ORFs of 52 and 59 codons on the complementary strand. The tRNAAsp gene is located entirely within the ORF of 91 codons. The first 366 bp of the fragment correspond to 376 bp at one end of a recently published (1) sequence from the broad bean (Vicia faba) chloroplast genome. These regions contain the tRNAGlu and tRNATyr genes, which are identical and separated by 60 bp in both species. These two genes are probably cotranscribed. The intergenic regions in the corresponding segments from the two species are, except for a 10 bp deletion in the pea sequence, 94% homologous.
