Protein bodies from the cotyledons of Cytisus scoparius L. (Link). Ultrastructure, isolation, and subunit composition of albumin, legumin and vicilin.

The structure of protein bodies differs in the upper and lower parts of the cotyledons of mature seeds of Cytisus scoparius L. The palisade-mesophyll cells contain essentially homogeneous protein bodies, without globoids, but the protein bodies of the spongy-mesophyll cells are heterogeneous, with numerous globoids. Albumins, legumins and vicilins were selectively extracted from isolated protein bodies and their subunits separated by SDS-PAGE, under non-reducing and reducing conditions.
