✦ Synopsis

To determine protein differences of grain sorghum disomics and trisomics, we analyzed leaf extracts from six trisomics and a disomic control by disc gel, gel isoelectric focusing, and SDS gel electrophoresis. Based on the number and position of protein bands revealed by Coomassie blue staining, the disomic control could be differentiated from the trisomics, and trisomics could be shown to differ among themselves in most cases. SDS gel revealed the most protein bands, followed by isoelectric focusing and disc gel. However, disc gel electrophoresis was the simplest technique of the three and was just as effective in identifying trisomics and differentiating trisomics from the disomic control.
