L.  aFree amino acid and protein modification in southernpea (Vigna unquiculata L. Walp.) with glyphosate.  c1994  aTotal seed protein content, amino acids and polypeptides were examined following desiccation of southernpea (Vigna unquiculata L. Walp.) plants with glyphosate [N-(phosphonomethyl) glycine]. Seed protein weight of mature seeds was not reduced by the desiccation process, however, protein content of more immature seed was reduced. Polypeptides were reduced in the same way. Free amino acid evaluation indicated that histidine increased up to four time in those seeds that were immature at that time of treatment. No differences were detected in bound amino acid content. Electrophoretic analysis during germination indicated that the proteins reduced in immature seeds with glyphosate desiccation were storage class proteins.  aglyphosate  ahistidine  apolypeptides  aAmino acid  aContent  aDesiccation  aHerbicide  aProtein  aSeed  aSouthernpea1 aCOLE, A.
