Abstract:
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 (32)P-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.

Transgenic Plants
The first-ever transgenic plant was a tobacco plant developed in 1983 that showed resistance against the tobacco mosaic virus. Since then, many transgenic plants have been developed and commercialized for improving the agricultural, ornamental, and horticultural value of a crop plant. Transgenic...

Each of these chemical modifications is carried by a specific enzyme, post-transcription. All of these enzymes have unique base and site-specificity. Methylation, the most common chemical modification, is carried by at least nine different enzymes, with...
