DIFFERENTIAL ACCUMULATION OF SOYBEAN SEED STORAGE PROTEIN SUBUNITS IN RESPONSE TO SULFUR AND NITROGEN NUTRITIONAL SOURCES

Soybean (Glycine max [L.] Merr.) seed storage proteins consist of subunits that differ in amino acid profile, the β-subunit of 7S protein being essentially devoid of the S-containing amino acids, methionine and cysteine.Our objective was to examine the interaction of N and S nutrition on the relative abundance of these storage protein subunits in
