Legumin Synthesis in Developing Cotyledons of Vicia faba L.
The synthesis of legumin in developing cotyledons of Vicia faba L. has been examined as a potential system for approaching the problem of differential gene expression. The pattern of legumin synthesis was determined during the growth of the cotyledon by microcomplement fixation which provided a sensitive and specific assay for legumin in the presence of vicilin. Legumin was detected even in young cotyledons. However, when the cotyledons were about 10 millimeters long, and cell division was essentially complete, there was a sharp increase in the rate of legumin accumulation.
