Species relationships in Bulnesia as shown by seed protein electrophoresis

The seed proteins of seven species of Bulnesia were studied by polyacrylamide electrophoresis. Some of the bands are characteristic and constant "markers" of each species; these allow the unequivocal identification of their electrophoregrams. In total 84 different bands were identified. Th...
