title: The barley chloroplast DNA atpBE, trnM2, and trnV1 loci.
abstract: The nucleotide sequence of a barley chloroplast DNA 3.7 kb SmaI-HindIII fragment is presented. This fragment contains atpBE, the genes for the beta and epsilon subunits of ATPase; trnM2, the gene for tRNA2met; and trnV1, the gene for tRNA1va1. The atpE-trnM2 interval is 126 bp and trnM2 is transcribed towards atpBE. The trnM2-trnV1 interval is 203 bp and trnV1 is transcribed away from trnM2. The trnV1 locus has a 597 bp intervening sequence. the organization and sequences of these genes are compared to the analogous genes from maize and tobacco chloroplast DNA. Using the latter comparisons the nature of sequence divergence between chloroplast DNAs is discussed.
