| Research Abstract: |
| We have studied the genetic relationship among cereals, cereal-like |
| amaranthus and other plants through electrophoretic and |
| isoelectrophoretic patterns of proteins. We found that the major |
| prolamin fraction in corn, sorghum, potato and cassava was monomeric |
| with MW subunits of 20-45kd. In prolamins a single sequence was |
| observed suggesting that prolamin homology arose through duplication |
| and mutation of a single ancestral gene. Prolamin sequence analyses |
| can predict evolutionary relationships of cereals. |
| New methods were used for this study such as differential scanning |
| calorimetry, circular dichroism, fluorometry, sequence analysis, |
| blotting, microscopy. |
