Summary Isolated chloroplasts from broad bean and common bean were found to contain a minimum of 31 and 32 tRNA species, respectively. These individual chloroplast tRNAs were 32P-labeled in vitro and hybridized to DNA fragments obtained upon digestion of broad bean and common bean chloroplast DNAs with various restriction endonucleases. At least 30 tRNA genes were localized on the physical maps of the two chloroplast genomes. Comparison of the broad bean tRNA gene map to that of common bean revealed DNA sequence rearrangements, such as inversions, insertions/ deletions and duplications, within these two members of the Legu minosae family.
