Restriction site maps of Sesamum indicum were constructed using 30 endonucleases and 106 tobacco clones. Clonning of PstI, HindIII, SacI fragments resulted the complete clone bank of the the genome. The gene arrangement of the Sesamum indicum similar to that of the tobacco. However, sequencing of the small single copy region of the genome reveals three independent small inversions compare to that of the tobacco. Some of the small single copy region show high sequence divergence among species and the sequences are phylogenetically useful to resolving the species relationships in the genus. The sequence data strongly indicated the multiple origins of the commonly cultivated Sesamum indicum, one from S. radiatum and the other from S. latifolium.
