ELECTROPHORETIC SEED GLOBULIN PATTERNS IN SOME NEW-WORLD LUPINUS SPECIES

Comparative SDS-PAGE analysis of seed globulins covered 74 accessions representing 19 New World Lupinus species, 18 North American lupins an d one South American species: L. mutabilis. The species investigated s howed major, well-defined polypeptide bands in the approximate M(r) ra nge of 40-75 kDa. In general, intraspecific variation blurred interspe cific differences; L. mutabilis could not be distinguished from the No rth American lupins. Of the taxa investigated, only L. subcarnosus and L. succulentus displayed some species-specific features. The American species examined showed different seed globulin patterns from those r eported earlier for the smooth-seeded and for the rough-seeded Old Wor ld lupins.
